In Brief ...
Motorola Analog and Interface Integrated Circuits cover a
much broader range of products than the traditional op amps!
regulators/consumer-image associated with Analog suppliers. Analog circuit technology currently influences the design
and architecture of equipment for all major markets. As with
other integrated circuit technologies, Analog circuit design
techniques and processes have been continually refined and
updated to meet the needs of these diversified markets.
Operational amplifiers have utilized JFET inputs for
improved performance, plus innovative design and trimming
concepts have evolved for improved high performance and
precision characteristics. In analog power ICs, basic voltage
regulators have been refined to include higher current and
voltage levels, low dropout regulators, and more precise
three-terminal fixed and adjustable voltages. The power area
continues to expand into switching regulators, power supply
control and supervisory circuits, motor controllers, and battery
charging controllers.
Analog designs also offer a wide array of line drivers,
receivers and transceivers for many of the EIA, European,
IEEE and IBM interface standards. Peripheral drivers for a
variety of devices are also offered. In addition to these key
interface functions, hard disk drive read channel circuits,
10BASE-T and Ethernet circuits are also available.
In Data Conversion, a high performance video speed flash
converter is available, as well as a variety of CMOS and
Sigma-Delta converters. Analog circuit technology has also
provided precision low-voltage references for use in Data
Conversion and other low temperature drift applications.
A host of special purpose analog devices have also been
developed. These circuits find applications in telecommunications, radio, television, automotive, RF communications, and
data transmission. These products have reduced the cost of
RF communications, and have provided capabilities in telecommunications which make the telephone line convenient
for both voice and data communications. Analog developments have also reduced the many discrete components
formerly required for consumer functions to a few IC packages
and have made significant contributions to the rapidly growing
market for electronics in automotive applications.
The table of contents provides a perspective of the many
markets served by Analogllnterface ICs and of Motorola's
involvement in these areas.

Voltage References

In Brief ...
Motorola's line of precIsion voltage references is
designed for applications requiring high initial accuracy, low
temperature drift, and long term stability. Initial accuracies of
±1.0%, and ±2.0% mean production line adjustments can be
eliminated. Temperature coefficients of 25 ppm/DC max
(typically 10 ppm/DC) provide excellent stability. Uses for the
references include D/A converters, AID converters,
precision power supplies, voltmeter systems, temperature
monitors, and many others.

Micropower Voltage
Reference Diodes

11

The LM285/LM385 series are micropower two-terminal bandgap voltage
regulator diodes. Designed to operate over a wide current range of 10 !lA to
20 mA, these devices feature exceptionally low dynamic impedance, low
noise and stable operation over time and temperature. Tight voltage
tolerances are achieved by on-chip trimming. The large dynamic operating
range enables these devices to be used in applications with widely varying
supplies with excellent regulation. Extremely low operating current make
these devices ideal for micropower circuitry like portable instrumentation,
regulators and other analog circuitry where extended battery life is required.
The LM285/LM385 series are packaged in a low cost T0-226AA plastic
case and are available in two voltage versions of 1.235 and 2.500 V as
denoted by the device suffix (see Ordering Information table). The LM285 is
specified over a -40°C to +85°C temperature range while the LM385 is rated
from O°C to +70°C.
The LM385 is also available in a surface mount plastic package in
voltages of 1.235 and 2.500 V.
• Operating Current from 10 !lA to 20 rnA
• 1.0%, 1.5%, 2.0% and 3.0% Initial Tolerance Grades

Providing the Reference Current
for Motorola Monolithic D/A Converters
The MC1403 makes an ideal reference for many monolithic D/A converters, requiring a stable current reference of
nominally 2.0 rnA. This can be easily obtained from the
MC1403 with the addition of a series resistor, R1 . A variable
resistor, R2, is recommended to provide means for fullscale adjust on the D/A converter.

• Caution: System stability may be affected if output capacitance
exceeds 1.0 ~F. Using higher capacitance values is not
recommended and should be carefully considered.

The resistor R3 improves temperature performance by
matching the impedance on both inputs olthe D/A reference
amplifier. The capacitor decouples any noise present on the
reference line. It is essential if the D/A converter is located
any appreciable distance from the reference.
A single MC1403 reference can provide the required
current input for up to five of the monolithic D/A converters.

PROGRAMMABLE
PRECISION REFERENCES

The TL431, A, B integrated circuits are three-terminal programmable
shunt regulator diodes. These monolithic IC voltage references operate as a
low temperature coefficient zener which is programmable from Vref to 36 V
with two external resistors. These devices exhibit a wide operating current
range of 1.0 rnA to 100 rnA with a typical dynamic impedance of 0.22 n. The
characteristics of these references make them excellent replacements for
zener diodes in many applications such as digital voltmeters, power
supplies, and op amp circuitry. The 2.5 V reference makes it convenient to
obtain a stable reference from 5.0 V logic supplies, and since the TL431 , A,
B operates as a shunt regulator, it can be used as either a positive or
negative voltage reference.

MC10319

High Speed a-Bit
Analog-to-Digital Converter

a

The MC10319 is an 8-bit high speed parallel flash AID converter. The
device employs an internal Grey Code structure to eliminate large output
errors on fast slewing input signals. It is fully TTL compatible, requiring a
+ 5.0 V supply and a wide tolerance negative supply of - 3.0 to - 6.0 V.
Three-state TTL outputs allow direct drive of a data bus oi; common I/O
memory.
The MC10319 contains 256 parallel comparators across a precision input
reference network. The comparator outputs are fed to latches and then to .an
encoder network, to produce an 8-bit data byte plus an overrange bit. The
data is latched and converted to 3-state L8-TTL outputs. The overrange bit
is always active to allow for either sensing olthe overrange condition or ease
of interconnecting a pair of devices to produce a 9-bit AID converter.
Applications include video display and radar processing, high speed
instrumentation and TV broadcast encoding.

DESIGN GUIDELINES
Introduction

Reference

The MC1 0319 is a high speed, 8-bit, parallel (''flash'') type
analog-to-digital converter containing 256 comparators at
the front end. See Figure 17 for a block diagram. The
comparators are arranged such that one input of each is
referenced to evenly spaced voltages, derived from the
reference resistor ladder. The other input of the comparators
is connected to the input signal (Vin). Some of the
comparator's differential outputs will be ''true,'' while other
comparators will have "not true" outputs, depending on their
relative position. Their outputs are then latched, and
converted to an 8-bit Grey code by the Differential Latch
Array. The Grey code ensures that any input errors due to
cross talk, feed-thru, or timing disparities result in glitches at
the output of only a few LSBs, rather than the more traditional
1/2 scale and 1/4 scale glitches.
The Grey code is then translated to an 8-bit binary code,
and the differential levels are translated to TTL levels before
being applied to the output latches. Enable inputs at this final
stage permit the TTL outputs (except overrange) to be put
into a high impedance (3-state) condition.

The reference resistor ladder is composed of a string of
equal value resistors to provide 256 equally spaced voltages
for the comparators (see Figure 17 for the actual
configuration). The voltage difference between adjacent
comparators corresponds to 1 LSB of the input range. The
first comparator (closestto VRB) is referenced 1/2 LSB above
VRB, and 256th comparator (for the overrange) is referenced
1/2 LSB below VRT. The total resistance of the ladder is
nominally 130 n, ±20%, requiring 15.4 mA @ 2.0 V, and
7.7 mA @ 1.0 V. There is a nominal warm-up change of
~ +9.0% in the ladder resistance due to the +0.29%/OC
temperature coefficient.
The minimum recommended span [VRT - VRB] is 1.0 V. A
lower span will allow offsets and nonlinearities to become
significant. The maximum recommended span is 2.1 V due to
power limitations of the resistor ladder. The span may be
anywhere within the range of - 2.1 to + 2.1 V with respect to
ground, and VRB must be at least 1.3 V more positive than
VEE· The reference voltages must be stable and free of noise
and spikes, since the accuracy of a conversion is directly
related to the quality of the reference.
In most applications, the reference voltages will remain
fixed. In applications involving a varying reference for
modulation or signal scrambling, the modulating signal may
be applied to VRT, or VRB, or both. The output will vary
inversly with the reference signal, introducing a nonlinearity
into the transfer function. The addition of the modulating
signal and the dc level applied to the reference must be such
that the absolute voltage at VRT and VRB is maintained within
the values listed in the Recommended Operating Limits. The
RMS value of the span must be maintained .. 2.1 V.
VRM (Pin 1) is the midpoint of the resistor ladder, excluding
the Overrange comparator. The voltage at VRM is:

ANALOG SECTION
Signal Input
The signal. voltage to be digitized (Vin) is applied
simultaneously to one input of each of the 256 comparators
through Pin 14. The other inputs of the comparators are
connected to 256 evenly spaced voltages derived from the
reference ladder. The output code depends on the relative
position of the input signal and the reference voltages. The
comparators have a bandwidth of > 50 MHz, which is more
than sufficient for the allowable (Nyquist Theorem) input
frequency of 12.5 MHz.
The current into Pin 14 varies linearly from 0 (when
Yin = VRB) to ~60 jlA (when Yin =VRT). If Yin is taken below
VRB or above VRT, the input current will remain at the value
corresponding to VRB and VRT respectively (see Figure 5).
However, Yin must be maintained within the absolute range of
±2.5 V (with respect to ground) - otherwise excessive
currents will result at Pin 14, due to internal clamps.
The input capacitance at Pin 14 is typically 36 pF if
[VRT - VRB] is 2.0 V, and increases to 55 pF if [VRT - VRB]
is reduced to 1.0 V (see Figure 4). The capacitance is
constant as Yin varies from VRT down to ~0.1 V above VRB.
Taking Yin to VRB will show an increase in the capacitance of
~50%. If Yin is taken above VRT, or below VRB, the
capacitance will stay at the values corresponding to VRT
and VRB, respectively.
The source impedance of the signal voltage should be
maintained below 100 n (at the frequencies of interest) in
order to avoid sampling errors.

In most applications, bypassing this pin to ground (0.1 JlF) is
sufficient to maintain accuracy. In applications involving very
high frequencies, and where linearity is critical, it may be
necessary to trim the voltage at the midpoint. A means for
accomplishing this is indicated in Figure 18.
Power Supplies

VCC(A) is the positive power supply for the comparators,
and VCC(D) is the positive power supplyforthe digital portion.
Both are to be +5.0 V, ±10%, and the two are to be within
100 mV of each other. There is indirect internal coupling
between VCC(D) and VCC(A).lf they are powered separately,
and one supply fails, there will be current flow through the
MC10319 to the failed supply.

6-13

MC10319
ICC(A) is nominally 17 rnA, and does not vary with clock
frequency or with Vin. It does vary linearly with VCC(A).ICC(D)
is nominally 90 rnA, and is independent of clock frequency. It
does vary, however, by 6 to 7 rnA as Vin is changed, with the
lowest current occurring when Vin = VRT It varies linearly
with VCC(D).
VEE is the negative power supply for the comparators,
and is to be within the range - 3.0 to - 6.0 V. Additionally,
VEE must be at least 1.3 V more negative than VRS.IEE is a
nominal- 10 rnA, and is independent of clock frequency, Vin
and VEE.
'
For proper operation, the supplies must be bypassed at
the IC. A 10 J.lF tantalum, in parallel with a 0.1 J.lF ceramic is
recommended for each supply to ground.

DIGITAL SECTION
Clock

II

The Clock input is TTL compatible with a typical
frequency range of 0 to 30 MHz. There is no duty cycle
limitations, but the minimum low and high times must be
adhered to. See Figure 7 for the input current requirements.
The conversion sequence is shown in Figure 19, and is
as follows:
• On the rising edge, the data output latches are latched
with old data, and the comparator output latches are
released to follow the input signal (Vin).
• During the high time, the comparators track the input
signal. The data output latches retain the old data.
• On the falling edge, the comparator outputs are latched
with the data immediately prior to this edge. The
conversion to digital occurs within the device, and the
data output latches are released to indicate the new data
within 20 ns.
• Duringthe clock low time, the comparator outputs remain
latched, and the data output latches remain transparent.
A summary of the sequence is that data present at Vin
just prior to the Clock falling edge is digitized and
available at the data outputs immediately after that same
falling edge.

The comparator output latches provide the circuit with an
effective sample-and-hold function, eliminating the need for
an external sample-and-hold.
Enable Inputs
The two Enable inputs are TTL compatible, and are used
to change the data outputs (D7-DO) from active to 3-state.
This capability allows cascading two MC1 0319s into a 9-bit
configuration, flip-flopping two MC10319s into a 50 MHz
configuration, connecting the outputs directly to a data bus,
multiplexing multiple converters, etc. See the Applications
Information section for more details. For the outputs to be
active, Pin 19 must be a Logic "1", and Pin 20 must be a Logic
"0". Changing either input will put the outputs into the high
impedance mode. The Enable inputs affect only the state
of the outputs - they do not inhibit a conversion. The input
current into Pins 19 and 20 is shown in Figure 6, and the
input/output timing is shown in Figure 1 and 20. Leaving
either pin open is equivalent to a Logic "1", although good
design practice dictates that an input should never be
left open.
The Overrange output (Pin 3) is not affected by the Enable
inputs as it does not have 3-state capability.
Outputs
The Data outputs are TTL level outputs with high
impedance capability. Pin 4 is the MSS (D7), and Pin 21 is the
LSB (DO). The eight outputs are active as long as the Enable
inputs are true (Pin 19 =high, Pin 20 =low). The timing of the
outputs relative to the Clock input and the Enable inputs is
shown in Figures 1 and 20. Figures 8 and 9 indicate the
output voltage versus load current, while Figure 3 indicates
the leakage current when in the high impedance mode.
The output code is natural binary, depicted in the
table below.
The Overrange output (Pin 3) goes high when the input,
Vin, is more positive than VRT - 1/2 LSB. This output is
always active - it does not have high impedance capability.
Besides being used to indicate an input overrange, it is
additionally used for cascading two MC10319s to form a
9-bit AID converter (see Figure 27).

MOTOROLA ANALOG IC DEVICE DATA

MC10319
GLOSSARY
Aperture Delay - The time difference between the sampling
signal (typically a clock edge) and the actual analog signal
converted. The actual signal converted may occur before or
after the sampling signal, depending on the internal
configuration of the converter.
Bipolar Input - A mode of operation whereby the analog
input (of an AID), or output (of a DAC), includes both
negative and positive values. Examples are - 1.0 to + 1.0 V,
- 5.0 to + 5.0 V, - 2.0 to + 8.0 V, etc.
Bipolar Offset Error - The difference between the actual
and ideal locations of the DOH to 01 H transition, where the
ideal location is 1/2 LSB above the most negative
reference voltage.

Load Regulation - The ability of a voltage regulator to
maintain a certain output voltage as the load current is varied.
The error is typically expressed as a percent of the nominal
output voltage.
LSB - Least Significant Bit. It is the lowest order bit of a
binary code.
Monotonicity - The characteristic of the transfer function
whereby increasing the input code (of a DAC), or the input
signal (of an AID), results in the output never decreasing.
MSB - Most Significant Bit. It is the highest order bit of a
binary code.
Natural Binary Code - A binary code defined by:
N =An2n + ... + A323 + A222 + A121 + A020

Bipolar Zero Error - The error (usually expressed in LSBs)
of the input voltage location (of an AID) of the 80H to 81 H
transition. The ideal location is 1/2 LSB above zero volts in
the case of an AID setup for a symmetrical bipolar input
(e.g., - 1.0 to + 1.0 V).

where each "A" coefficient has a value of 1 or O. Typically, all
zeroes correspond to a zero input voltage of an AID, and all
ones correspond to the most positive input voltage.

Differential Nonlinearity - The maximum deviation in the
actual step size (one transition level to another) from the ideal
step size. The ideal step size is defined as the Full Scale
Range divided by 2n (n =number of bits). This error must be
within ± 1 LSB for proper operation.

Offset Binary Code - Applicable only to bipolar input (or
output) data converters, it is the same as Natural Binary,
except that all zeros correspond to the most negative input
voltage (of an AID), while all ones correspond to the most
positive input.

ECL - Emitter coupled logic.

Power Supply Sensitivity - The change in a data
converter's performance with changes in the power supply
voltage(s). This parameter is usually expressed in percent of
full scale versus tN.

Full Scale Range (Actual) - The difference between the
actual minimum and maximum end points of the analog input
(of an AID).
Full Scale Range (Ideal) - The difference between the
actual minimum and maximum end points of the analog input
(of an AID), plus one LSB.
Gain Error - The difference between the actual and
expected gain (end point to end point), with respect to the
reference, of a data converter. The gain error is usually
expressed in LSBs.
Grey Code - Also known as reflected binary code, it is a
digital code such that each code differs from adjacent codes
by only one bit. Since more than one bit is never changed at
each transition, race condition errors are eliminated.
Integral Nonlinearity - The maximum error of an AID, or
DAC, transfer function from the ideal straight line connecting
the analog end points. This parameter is sensitive to
dynamics, and test conditions must be specified in order to
be meaningful. This parameter is the best overall indicator of
the device's performance.
Line Regulation - The ability of a voltage regulator to
maintain a certain output voltage as the input to the regulator
is varied. The error is typically expressed as a percent of the
nominal output voltage.

MOTOROLA ANALOG IC DEVICE DATA

Nyquist Theorem - See Sampling Theorem.

Quantitlzation Error - Also known as digitization error or
uncertainty. It is the inherent error involved in digitizing an
analog signal due to the finite number of steps at the digital
output versus the infinite number of values at the analog
input. This error is a minimum of ± 1/2 LSB.
Resolution - The smallest change which can be discerned
by an AID converter, or produced by a DAC. It is usually
expressed as the number of bits (n), where the converter has
2n possible states.
Sampling Theorem - Also known as the Nyquist Theorem.
It states that the sampling frequency of an AID must be no
less that 2x the highest frequency (of interest) of the analog
signal to be digitized in order to preserve the information of
that analog signal.
Unipolar Input:" A mode of operation whereby the analog
input range (of an AID), or output range (of a DAC), includes
values of a signal polarity. Examples are 0 to + 2.0 V, 0 to
- 5.0 V, 2.0 to 8.0 V, etc.
Unipolar Offset Error - The difference between the actual
and ideal locations of the DOH to 01 H tranSition, where the
ideal location is 112 LSB above the most negative
input voltage.

Interface Circuits

In Brief ...
Described in this section is Motorola's line of interface
circuits, which provide the means for interfacing with
microprocessor or digital systems and the external world, or
to other systems.
Also included are devices which allow a microprocessor
to communicate with its own array of memory and peripheral
1/0 circuits.
The line drivers, receivers, and transceivers permit
communication between systems over cables of several
thousand feet in length, and at data rates of up to several
megahertz. The common EIA data transmission standards,
several European standards, and IEEE-488 are addressed
by these devices.
The peripheral drivers are designed to handle high
current loads such as relay coils, lamps, stepper motors, and
others. Input levels to these drivers can be TTL, CMOS, high
voltage MOS, or other user defined levels. The display
drivers are designed for LCD or LED displays, and provide
various forms of decoding.

AM26LS30

Dual Differential (EIA-422-A)/
Quad Single-Ended
(EIA-423-A) Line Drivers
The AM26LS30 is a low power Schottky set of line drivers which can be
configured as two differential drivers which comply with EIA-422-A
standards, or as four single-ended drivers which comply with EIA-423-A
standards. A mode select pin and appropriate choice of power supplies
determine the mode. Each driver can source and sink currents in excess of
50mA.
In the differential mode (EIA-422-A), the drivers can be used up to
10 Mbaud. A disable pin for each driver permits setting the outputs into a
high impedance mode within a ±10 V common mode range.
In the single-ended mode (EIA-423-A), each driver has a slew rate
control pin which permits setting the slew rate of the output signal so as to
comply with EIA-423-A and FCC requirements and to reduce crosstalk .
When operated from symmetrical supplies (±5.0 V), the outputs exhibit zero
imbalance.
The AM26LS30 is available in a 16-pin plastic DIP and surface mount
package. Operating temperature range is -40° to +85°C.

QUAD EIA-422/423 Line
Receiver with Three-State
Outputs
Motorola's Quad EIA-42213 Receiver features four independent receiver
chains which comply with EIA Standards for the Electrical Characteristics of
Balanced/Unbalanced Voltage Digital Interface Circuits. Receiver outputs
are 74LS compatible, three-state structures which are forced to a high
impedance state when Pin 4 is a Logic "0" and Pin 12 is a Logic "1." A PNP
device buffers each output control pin to assure minimum loading for either
Logic "1" or Logic "0" inputs. In addition, each receiver chain has internal
hysteresis circuitry to improve noise margin and discourage output instability
for slowly changing input waveforms. A summary of AM26LS32 features
include:

High Voltage, High Current
Darlington Transistor Arrays
The seven NPN Darlington connected transistors in these arrays are well
suited for driving lamps, relays, or printer hammers in a variety of industrial
and consumer applications. Their high breakdown voltage and internal
suppression diodes insure freedom from problems associated with inductive
loads. Peak inrush currents to 500 rnA permit them to drive incandescent
lamps.
The MC1413, B with a 2.7 kn series input resistor is well suited for
systems utilizing a 5.0 V TTL or CMOS Logic. The MC1416, B uses a series
10.5 kn resistor and is useful in 8.0 to 18 V MOS systems.

MOTOROLA ANALOG IC DEVICE DATA

MC1488
APPLICATIONS INFORMATION
The Electronic Industries Association EIA-232D specification
details the requirements for the interface between data processing
equipment and data communications equipment. This standard
specifies not only the number and type of interface leads, but also the
voltage levels to be used. The MCt 488 quad driver and its companion
circuit, the MCI489 quad receiver, provide a complete interface
system between DTL or TTL logic levels and the EIA-232D defined
levels. The EIA-232D requirements as applied to drivers are
discussed herein.
The required driver voltages are defined as between 5.0 and 15 V
in magnitude and are positive for a Logic "0" and negative for a Logic
"I." These voltages are so defined when the drivers are terminated
with a 3000 to 7000 n resistor. The MC1488 meets this voltage
requirement by converting a DTUTTL logic level into EIA-232D
levels with one stage of inversion.
The EIA-232D specification further requires that during transitions,
the driver output slew rate must not exceed 30 V per microsecond.
The inherent slew rate of the MC1488 is much too fast for this
requirement. The current limited output of the device can be used to
control this slew rate by connecting a capacitor to each driver output.
The required capacitor can be easily determined by using the
relationship C = lOS x I!..TII!..V from which Figure 12 is derived.
Accordingly, a 330 pF capacitor on each output will guarantee a
worst case slew rate of 30 V per microsecond.

should be placed in each power supply lead to prevent overheating in
this fault condition. These two diodes, as shown in Figure 13, could be
used to decouple all the driver packages in a system. (These same
diodes will allow the MC1488 to withstand momentary shorts to the
± 25 V limits specified in the earlier Standard EIA-232B.) The
addition of the diodes also permits the MC1488 to withstand faults
with power supplies of less than the 9.0 V stated above.

C, CAPACITANCE (pF)
The interface driver is also required to withstand an accidental
short to any other conductor in an interconnecting cable. The worst
possible signal on any conductor would be another driver using a
plus or minus 15 V, 500 mA source. The MC1488 is designed to
indefinitely withstand such a short to all four outputs in a package as
long as the power supply voltages are greater than 9.0 V (i.e., VCC
'" 9.0 V; VEE';; - 9.0 V). In some power supply designs, a loss of
system power causes a low impedance on the power supply outputs.
When this occurs, a low impedance to ground would exist at the
power inputs to the MC1488 effectively shorting the 300 n output
resistors to ground. If all four outputs were then shorted to plus or
minus 15 V, the power dissipation in these resistors would be
excessive. Therefore, if the system is designed to permit low
impedances to ground at the power supplies of the drivers, a diode

MOTOROLA ANALOG IC DEVICE DATA

Other Applications
The MC1488 is an extremely versatile line driver with a myriad of
possible applications. Several features of the drivers enhance this
versatility:
1. Output Current Limiting - this enables the circuit designer to
define the output voltage levels independent of power supplies and
can be accomplished by diode clamping of the output pins. Figure 14
shows the MC148B used as a DTL to MaS translator where the high
level voltage output is clamped one diode above ground. The
resistor divider shown is used to reduce the output voltage below the
300 mV above ground MaS input level limit.
2. Power Supply Range - as can be seen from the schematic
drawing of the drivers, the positive and negative driving elements of
the device are essentially independent and do not require matching
power supplies. In fact, the positive supply can vary from a minimum
7.0 V (required for driving the negative pulldown section) to the
maximum specified 15 V. The negative supply can vary from
approximately - 2.5 V to the minimum specHied -15 V. The MC14BB
will drive the output to within 2.0 V of the positive or negative supplies
as long as the current output limits are not exceeded. The combination
of the current limiting and supply voltage features allow a wide
combination of possible outputs within the same quad package. Thus
if only a portion of the four drivers are used for driving EIA-232D
lines, the remainder could be used for DTL to MaS or even DTL to
DTL translation. Figure 15 shows one such combination.

and the EIA-232D defined levels. The EIA-232D
requirements as applied to receivers are discussed herein.
The required input impedance is defined as between
3000 nand 7000 n for input voltages between 3.0 and 25 V
in magnitude; and any voltage on the receiver input in an
open circuit condition must be less than 2.0 V in magnitude.
The MC1489 circuits meet these requirements with a
maximum open circuit voltage of one VSE.
The receiver shall detect a voltage between - 3.0 and
- 25 Vasa Logic "1" and inputs between 3.0 and 25 V as a
Logic "0." On some interchange leads, an open circuit of
power "OFF" condition (300 n or more to ground) shall be
decoded as an "OFF" condition or Logic "1." For this reason,
the input hysteresis thresholds of the MC1489 circuits are all
above ground. Thus an open or grounded input will cause the
same output as a negative or Logic "1" input.
Device Characteristics
The MC1489 interface receivers have internal feedback
from the second stage to the input stage providing input
hysteresis for noise rejection. The MC1489 input has typical

turn-on voltage of 1.25 V and turn-off of 1.0 V for a typical
hysteresis of 250 mY. The MC1489A has typical turn-on of
1.95 V and turn-off of 0.8 V for typically 1.15 V of hysteresis.
Each receiver section has an external response control
node in addition to the input and output pins, thereby allowing
the designer to vary the input threshold voltage levels. A
resistor can be connected between this node and an external
power supply. Figures 2, 4 and 5 illustrate the input threshold
voltage shift possible through this technique.
This response node can also be used for the filtering of
high frequency, high energy noise pulses. Figures 8 and 9
show typical noise pulse rejection for external capacitors of
various sizes.
These two operations on the response node can be
combined or used individually for many combinations of
interfacing applications. The MC1489 circuits are particularly
useful for interfacing between MOS circuits and MDTUMTTL
logic systems. In this application, the input threshold voltages
are adjusted (with the appropriate supply and resistor values)
to fall in the center of the MOS voltage logic levels (see
Figure 10).
The response node may also be used as the receiver input
as long as the designer realizes that he may not drive this
node with a low impedance source to a voltage greater than
one diode above ground or less than one diode below
ground. This feature is demonstrated in Figure 11 where two
receivers are slaved to the same line that must still meet the
EIA-232D impedance requirement.

MC14C88B
Quad Low Power Line Driver
The MC14C88B is a low power monolithic quad line driver, using BiMOS
technology, which conforms to EIA-232-D, EIA-562, and CCITT V.28. The
inputs feature TTL and CMOS compatibility with minimal loading. The
outputs feature internally controlled slew rate limiting, eliminating the need
for external capacitors. Power off output impedance exceeds 300 Q, and
current limiting protects the outputs in the event of short circuits.
Power supply current is less than 160 itA over the supply voltage range of
±4.5 to ±15 V. EIA-232-D performance is guaranteed with a minimum
supply voltage of ±6.5 V.
The MC14C88B is pin compatible with the MC1488, SN75188,
SN75C188, DS1488, and DS14C88. This device is available in 14 pin plastic
DIP, and surface mount packaging.

STANDARDS COMPLIANCE
The MC14CBB is designed to comply with EIA-232-D
(formerly R8-232), the newer EIA-562 (which is a higher
speed version of the EIA-232), and CCIIT's V.2B. EIA-562
was written around modern integrated circuit technology,
whereas EIA-232 retains many of the specs written around
Parameter

the electro-mechanical circuitry in use at the time of its
creation. Yet the user will find enough similarities to allow a
certain amount of compatibility among equipment built to the
two standards. Following is a summary of the key

MC14C888
APPLICATIONS INFORMATION
Description
The MC14C88 was designed to be a direct replacement
for the MC1488 in that it meets all EIA-232 specifications.
However, use is extended as the MC14C88 also meets the
faster EIA-562 and CCITT V.28 specifications. Slew rate
limited outputs conform to the mentioned specifications and
eliminate the need for external output capacitors. Low
power consumption is made possible by SiMOS technology.
Power supply current is limited to less than 160 f,tA, plus
load currents over the supply voltage range of ±4.5 V to
±15 V (see Figure 2).
Outputs
The output low or high voltage depends on the state of the
inputs, the load current, and the supply voltage (see Table 1
and Figure 3). The graphs apply to each driver regardless of
how many other drivers within the package are supplying
load current.

or rise above VEE by more than 39 V, excessive currents will
flow at the input pin. Open input pins are equivalent to logic
high, but good design practices dictate that inputs should
never be left open.
Operating Temperature Range
The ambient operating temperature range is listed at -40°
to +85°C and meets EIA-232-D, EIA-562 and CCITT V.28
specifications over this temperature range. The maximum
ambient temperature is listed as +85°C. However, a lower
ambient may be required depending on system use, i.e.
specifically how many drivers within a package are used, and
at what current levels they are operating. The maximum
power which may be dissipated within the package is
determined by:

Driver Inputs
The driver inputs determine the state of the outputs in
accordance with Table 1. The nominal threshold voltage for
the inputs is 1.4 Vdc, and for proper operation, the input
voltages should be restricted to the range Gnd to VCC.

Quad Low Power
Line Receivers
The MC14C89B and MC14C89AB are low monolithic quad line receivers
using bipolar technology, which conform to the EIA-232-E, EIA--562 and
CCITT V.28 Recommendations. The outputs feature LSTTL and CMOS
compatibility for easy interface to +5.0 V digital systems. Internal
time-domain filtering eliminates the need for external filter capacitors in most
cases.
The MC14C89B has an input hystereSiS of 0.35 V, while the MC14C89AB
hystereSiS is 0.95 V. The response control pins allow adjustment of the
threshold level if desired. Additionally, an external capacitor may be added
for additional noise filtering.
The MC14C89B and MC14C89AB are available in both a 14 pin

APPLICATIONS INFORMATION
Description
The MC14C89AB and MC14C89B are designed to be
direct replacements for the MC1489A and MC1489. Both
devices meet all EIA-232 specifications and also the faster
EIA-562 and CCITT V.28 specifications. Noise pulse
rejection circuitry eliminates the need for most response
control filter capacitors but does not exclude the possibility as
filtering is still possible at the Response Control (RC) pins.
Also, the Response Control pins allow for a user defined
selection of the threshold voltages. The MC14C89AB and
MC14C89B are manufactured with a bipolar technology
using low power techniques and consume at most 700 JAA,
plus load currents with a +5.0 V supply.

MC14C89B or 0.95 V for the MC14C89AB). Figure 7 plots
equation (1) for two values of Vbat and a range of RRC.
If an RC pin Is to be used for low pass filtering, the
capacitor chosen can be calculated by the equation,

where L3dB represents the desired -3 dB role-off frequency

Figure 9. Application to Adjust Thresholds
Input Pin

Outputs
The output low or high voltage depends on the state of the
inputs, the load current, the bias of the Response Control
pins, arid the supply voltage. Table 1 applies to each receiver,
regardless of how many other receivers within the package
are supplying load current.

Receiver Inputs and Response Control
The receiver inputs determine the state of the outputs in
accordance with Table 1. The nominal VIL and VIH
thresholds are 0.95 V and 1.90 V respectively for the
MC14C89AB. For the MC14C89B, the nominal VIL and VIH
thresholds are 0.95 and 1.30, respectively. The inputs are
able to withstand ±3O V referenced to ground. Should the
input voltage exceed ground by more than ± 30 V, excessive
currents will flow at the input pin. Open input pins will
generate a logic high output, but good design practices
dictate that inputs should never be left open.
The Response Control (RC) pins are coupled to the inputs
through a resistor string. The RC pins provide for adjustment
of the threshold voltages of the IC while preserving the
amount of hysteresis. Figure 10 shows a typical application
to adjust the threshold voltages. The RC pins also provide
access to an internal resistor string which permits low pass
filtering of the input signal within the IC. Like the input pins,
the RC pins should not be taken above or below ground by
more than ±30 V or excessive currents will flow at these pins.
The dependence of the low level threshold voltage (VIU upon
RRC and Vbat can be described by the following equation:

VIH can be found by calculating for VIL using equation (1)
then adding the hysteresis for each device (0.35 for the

7-54

Another feature of the MC14C89AB and MC14C89B is
input noise rejection. The inputs have the ability to ignore
pulses which exceed the VIH and VII:. thresholds but are less
than 1.0 J.ts in duration. As the duration of the pulse exceeds
1.0 J.tS, the noise pulse may still be ignored depending on its
amplitude. Figure 8 is a graph showing typical input noise
rejection as a function of pulse amplitude and pulse duration.
Figure 8 reflects data taken for an input with an unconnected
RC pin and applied to the MC14C89AB and MC14C89B.
Operating Temperature Range
The ambient operating temperature range is listed as
-40°C to +85°C, and the devices are designed to meet the
EIA-232-E, EIA-562 and CCITT V.28 specifications over
this temperature range. The timing characteristics are
guaranteed to meet the specifications at +25°C. The
maximum ambient operating temperature is listed as +85°C.
However, a lower ambient may be required depending on
system use (Le., specifically how many receivers within a
package are used), and at what current levels they are
operating. The maximum power which may be diSSipated
within the package is determined by:

Po

-

(max) -

TJ(max) - TA
RSJA

where: RSJA = thermal resistance (typ., 100°CIW for the
OIP and 125°CIW for the SOIC packages);
TJ(max) = maximum operating junction temperature
(150°C); and
TA =ambient temperature.
Po = {[(VCC- VOH) X IIOHI] or
[(YOU X IIOL I ]}each receiver + (VCC X ICC)
where: VCC = positive supply voltage;
VOH, VOL = measured or estimated from Figure 2
and 3;
ICC =measured quiescent supply current.
As indicated, the first term (in brackets) must be calculated
and summed for each of the four receivers, while the last
term is common to the entire package.

Quad Open-Collector
Bus Transceiver
This quad transceiver is designed to mate Schottky TTL or NMOS logic to
a low impedance bus. The Enable and Driver inputs are PNP buffered to
ensure low input loading. The Driver (Bus) output is open~ollector and can
sink up to 100 mA at 0.8 V, thus the bus can drive impedances as low as
100 Q. The receiver output is active pull-up and can drive ten Schottky TTL
loads.
An active-low Enable controls all four drivers allowing the outputs of
different device drivers to be connected together for party-line operation.
The line can be terminated at both ends and still give considerable noise
margin at the receiver. Typical receiver threshold is 2.0 V.
Advanced Schottky processing is utilized to assure fast propagation delay
times. Two ground pins are provided to improve ground current handling and
allow close decoupling between VCC and ground at the package. Both
ground pins should be tied to the ground bus external to the package.
• Driver Can Sink 100 mA at 0.8 V (Maximum)
• PNP Inputs for Low-Logic Loading
• Typical Driver Delay =10 ns
• Typical Receiver Delay =10 ns
• Schottky Processing for High Speed

NOTE 1: AHhough the MC3448A transceivers
are non-inverting, the 488-1978 bus callouts
appear inverted wHh respect to the MC68488
pin designations. This is because the
488-1978 Standard is defined for negative
logic, while all M6800 MPU components
make use of posHive logic formal.

MC3450

Quad MTTL Compatible
Line Receivers
The MC3450 features four MC751 07 type active pull up line receivers with
the addition of a common three-state strobe input. When the strobe input is
at a logic zero, each receiver outputstate is determined by the differential
voltage across its respective inputs. With the strobe high, the receiver
outputs are in the high impedance state.
The strobe input on both devices is buffered to present a strobe loading
factor of only one for all four receivers and inverted to provide best
compatability with standard decoder devices.

Receivers
The MC3450 can be used for slngle-ended as well as differential line
receiving. For slngle-ended line receiver applicatIons, such as are
encountered in min)computers, the configuration shown In Figure 15 can
be used. The voltage source, which generates Vref. should be designed
80thatllle Vr.fvoltagels hallway between VOH(mln)and VOL(max). The
maximum Input overdrive required to guarantee a gIven logic state Is
extremely small, 25 mV maximum. This low-lnput overdrive enhances
differential noise immunity. Also the high-Input Impedance of the line
receiver permits many receivers to be placed on a single line with
minimum load effects.

NOTES: 1. Reference IBM specffication GA22-6974-3 for test tenninology.
2. The fau~ protection Circuitry of the MC3481 and MC348S requires relatively clean input voHage wavefonns for current oparation. Noise pulses which
enter the threshold region (0.8 to 2.0 V) may cause the output to enter the fault protect mode. To exit the protect mode, ij is necessary to gate an
input of the effected driver to the low logic state.

MC3488A

Dual EIA-423/EIA-232D
Line Driver
The MC3488A dual is single-ended line driver has been designed to
satisfy the requirements of EIA standards EIA-423 and EIA-232D, as well
as CCITT X.26, X.28 and Federal Standard FIDS1030. It is suitable for use
where signal wave shaping is desired and the output load resistance is
greaterthan 450 ohms. Output slew rates are adjustable from 1.0 j.!s to
100 j.!S by a single external resistor. Output level and slew rate are
insensitive to power supply variations. Input undershoot diodes limit
transients below ground and output current limiting is provided in both output
states.
The MC3488A has a standard 1.5 V input logic threshold for TTL or
NMOS compatibility..

IEEE 802.3 10BASE-T
Transceiver

II

The Motorola 10BASE-T transceiver, designed to comply with the ISO
8802-3 [IEEE 802.3] 10BASE-T specification, will support a Medium
Dependent Interface (MDI) in an embedded Media Attachment Unit (MAU)'.
The interface supporting the Data Terminal Equipment (DTE) is TTL, CMOS,
and raised ECl compatible, and the interface to the Twisted Pair (TP) media
is supported through standard 1OBASE-T filters and transformers.
Differential data intended for the TP media is provided a 50 ns pre-emphasis
and data at the TP receiver is screened by Smart Squelch circuitry for
specific threshold, pulse Width, and sequence requirements.
Other features of the MC34055 include: Collision and Jabber detection
status outputs, select mode pins for forcing loop Back and Full-Duplex
operation, a Signal Quality Error pin for testing the collision detect circuitry
without affecting the TP output, and a lED driver for Link Integrity status. An
on-chip oscillator, capable of receiving a clock input or operating under
crystal control, is also provided for internal timing and driving a buffered
clock output.
The MC34055 is manufactured on a BiCMOS process and is packaged in
a 24 pin SOIC.

FUNCTIONAL DESCRIPTION
Introduction
The Motorola 1OBASE-T transceiver, designed to comply
with the ISO 8802-3[IEEE 802.3) 10BASE-T specification,
will support one Medium Dependent Interface (MOl) through
standard 10BASE-T filters and transformers. Although the
device is capable of being used in embedded or external
Medium Attachment Units (MAU), it was primarily designed
for use in repeater or hub applications. For this reason a
digital interface is provided rather than an AUI interface. This
interface is TTL, CMOS, and raised ECl compatible and
allows for easy connection in hub applications.
Other features of the MC34055 include: select mode pins
of forcing loop-8ack and Full-Duplex operation; a Signal
Quality Error pin for testing the collision detect circuitry
without affecting the twisted pair output; and lED drivers for
Link Integrity status; Collision detection; and Jabber
detection. An on chip oscillator, capable of receiving a clock
input or operating under crystal control, is also provided for
internal timing and driving a buffered clock output.

The inputs were not intended to be used simultaneously in a
single application and are internally logically combined. The
unused input should be disabled by connection to VCC.
When data transmission is intended, the MC34055
detects the first falling edge of the Manchester encoded
frame at the input being used, synchronizes the on chip
oscillator (Pins 23 and 24) and asserts the twisted pair driver
output to full differential amplitude within 25 ns if the driver
enable pin (TX EN H) is previously asserted. Also, since
twisted pair attenuates a 10 MHz signal more than a 5.0 MHz
signal the 10BASE-T standard requires that data applied to
the twisted pair receive pre-equalization. To fulfill this
requirement the MC34055 provides an additional 730 mV for
approximately 50 ns to output data. This is accomplished
over the single pair of differential driver pins. TX+ and TX-,
and effectively equalizes the power of all data components at
the receiver. Figure 7 A shows a 10 MHz waveform. Figure 7B
shows the effect of pre-emphasis on a 5.0 MHz waveform.
Manchester encoded data with the pattern shown in Figure
7A would represent a repeating pattern of zeros (000000... ).
Figure 7B would represent an alternating pattern of ones and
zeros (0101010 ... ).

Data Transmission
For data intended for the twisted pair, the MC34055 has
two data inputs, TX Data A and TX Data B. TX Data A is
CMOS compatible and TX Data B is raised ECl compatible.

MC34055
The figures show the voltage waveforms on the differential
driver output pins. To actually meet the 10BASE-T
specification requires bandpass filtering and a pulse
transformer.
The output voltage waveform specifications of the IEEE
802.3. standard require that voltages impressed on the
twisted pair meet .a voltage template. The MC34055 can
meet the voltage template for all the 1OBASE-T applications

initiated. In this event, the transmit differential driver will
remain active for the entire frame interval and the link pulse
will not affect more than one bit interval.
The MC34055 also has Jabber circuitry to detect and
disable the twisted pair driver in the event .that a serial
controller fails constantly transmitting. Should any data
source try to transmit longer than 20 ms minimum, the Jabber
function will disable the differential driver outputs, the

by choosing the appropriate low pass filter and external
components in the driver output circuitry. When the
differential transmit driver output pins are configured to drive
the bandpass filters and pulse transformer as shown in
Figure 8, the resultant waveform is capable of meeting the
voltage template.
Following the end-of-frame activity, an internal pull-up
resistor pulls TX Data AlB high and causes the differential
driver to maintain full differential output voltage for
approximately 250 ns. The differential driver interprets the
lack of transition activity as an end of frame and starts an idle
timer. Should another frame intended for the twisted pair
arrive before the idle timer expires(-250 ns), the idle timer
will be reset, if not, the transmit driver function will begin the
decay to idle process. During idle periods the differential
driver must force the media to a minimal differential voltage
unless a link beat is being produced. The transition to
minimal voltage is subject to performance requirements in
the IEEE specification and is met by the MC34055 when the
appropriate filters and transformers are used to interface to
the media.
The MC34055 differential driver generates link pulses
(beats) during idle periods. The link pulses produced are
singular positive (TX+ positive with respect to TX-) pulses
applied to the media at 16 ms intervals and last
approximately 100 ns. The link pulses allow the receiver at
the other end of the link to verify the validity of the segment.
There is the possibility, due to the two asynchronous
sources, that one of the two input pins (TX Data A or TX Data
B) will receive frame activity immediately after a link pulse is

collision presence detector and the internal loop back
function. Also, two status indicator pins, CTL Hand JABB H
are asserted. The MC34055 will remain in the jabber state
until the TX EN H pin is pulled low or the jabbering input
ceases to toggle for a minimum of 500 ms. The status
indicator pins, CTL Hand JABB H will also sink up to 20 rnA
and can therefore support external LEOs.
The driver also works with the receiver to provide
loop-back. Under normal operating conditions (Loop L= "1"),
the data applied to the TX Data AlB pins is looped back
internally to the RX Data AlB pins. This function is disabled
when there is a collision condition or FULLD L is low.
Data Reception
Data intended for the DTE proceeds from the twisted pair
to the isolation transformer and bandpass filters before
reaching the differential receiver terminals. Figure 9 shows
the configuration of the external media receive circuitry. Once
transitions at the receiver terminals (RX+ and RX-) are
detected, the on-chip oscillator is synchronized and the
received data is screened by smart squelch circuitry for
validity. This qualification requires incoming data to meet
amplitude and sequence requirements. If the data meets the
Smart Squelch requirements, the receiver enters the
unsquelch state and the data is forwarded to the RX Data AlB
output pins provided Loop L is not low. Two data outputs are
provided to increase design flexibility, RX Data A and RX
Data B. RX Data A is CMOSfTTL compatible and RX Data B
is raised ECL compatible.

Where: RT is a terminating resistor (1000),

The MC34055 powers up in a squelched and "link OK"
state, after which minimum and maximum link test and
maximum link fail timers are started. If valid data or a link
pulse is received after the link test minimum timer but before
the link fail maximum timer times out, the timers are reset and
begin counting again. In the event of missing or incorrect link
pulses, the MC34055 enters the link fail state whereby the
LNKFL H status pin is asserted until valid data or link pulse
activity appears at the receiver terminals.
Powering up in the squelched state assures that the data
path to the data output pin (RX Data AlB) is disabled, and
prevents noise at the receiver terminals (RX+/RX-), from
being interpreted as valid input data. Once transitions appear
at the receiver terminals, the smart squelch circuitry checks
for the smart squelch requirements to unsquelch; an
alternating sequence (1010 ... or 0101...) of pulses with
amplitude of at least 525 mV. This requirement is met by the
preamble of an IEEE 802.3 frame with good signal to noise
ratio.
After a pulse is received and checked for proper polarity
and amplitude, the pulse width is checked for proper
duration. If the duration is to short or too long the smart
squelch Circuitry resets and begins to look again for a proper
sequence. By requiring the differential pulses to meet
amplitude and sequence requirements, it is unlikely that
pulses due to crosstalk from coresident twisted pairs are
capable of causing the receiver to unsquelch. If a positive
pulse is received first and the differential driver is not
transmitting, the receiver should un squelch after three
alternating pulses. If a negative pulse is received first, one
additional pulse is required before unsquelch. If the

differential driver is transmitting, three additional pulses are
required to unsquelch.
After meeting the smart squelch requirements, the
MC34055 will pull high the RX EN H pin and enable the path
to the receive data pin (RX D&ta AlB) provided the MC34055
is not in the loop back test mode (Loop L low). If the receiver
unsquelches, the receive enable pin remains high and the
data path to the receive data pin remains enabled until
transitions cease to exist at the receiver terminals. Valid data
reception is also indicated by high/low transitions of the
LNKFL H pin at 100 ms intervals. When transitions at the
differential terminals cease, marking the end of frame activity,
the receiver re-enters the squelch state, pulls Iowan the RX
EN H pin, and begins accepting valid link pulses until the start
of the next 802.3 frame.
If the MC34055 is requested to begin transmitting (TX EN
H is asserted), and the receiver unsquelches simultaneously,
there is a collision. Also, if the MC34055 driver enable pin is
previously asserted and the receiver detects valid transition
activity, the receiver Smart Squelch Circuitry verifies the
possibility of collision by requiring three extra transitions at
the differential receiver before the unsquelch condition is
reached. If un squelch occurs, a collision condition exists.
During all collision conditions the MC34055 asserts the CTL
H status pin for the duration of the condition and for a time
after the end of collision.
During a collision condition the receive and transmit paths
are still both enabled allowing transparency to the media.
Either the presence of simultaneous transmit and receive
activity or the condition of the CTL H status pin can be used
by the communications controller to acknowledge and react
to the collision. In applications where a 10 MHz collision
signal is required by an SIA, the combination of this status pin
and the clock oscillator output can be logically combined to
provide a 10 MHz output. If the DTE reacts to the collision
and ceases transmitting, the MC34055 will decay to idle until
a re-transmit is attempted.

Crystal Oscillator
The MC34055 has an on-chip clock oscillator used to
provide a reliable and accurate time reference to all the
internal timers. The oscillator can be run with a crystal or
driven at Pin 24 from an external clock source. Also provided
is a buffered clock output which is useful if the MC34055 is to
be used in a repeater or concentrator application.

MC34055
LOOP L Test Mode
If the Loop L pin is low, the MC34055 is in a test mode
whereby the data at the input pin (TX Data AlB) is being
looped back internally to the receive data pin(RX Data AlB).
In this mode the data path from the differential receiver
terminals to the receive data output pins (RX Data AlB) is
disconnected whiJe the Smart Squelch functionality of the
differential receiver is still operational. This test mode allows
the DTE to test the MC34055 internal loop back circuitry
since the data is looped back to the receive circuitry as close
to the twisted pair interface as possible.

minimUm, the differential driver, the collision detect, and
internal loop back circuits are disabled. To announce the
presence of a jabber condition, both the CTL H and the JABB
H status output pins are assertf3d. In order to end the jabber
condition, the TX Data AlB input must stop toggling, or the TX
EN H pin must be pulled low for a minimum of 500 ms. The
status output pins have the ability to drive an external led and
were added to facilitize network .manageability. The jabber
status outputs will not assert during power up or power down.

Signal Quality Error Test

The MC34055 can be operated in a full-duplex mode if
required. When the FULLD L pin is pulled low the device will
enter the full duplex mode. This mode allows the transmitter
and driver to operate independently. Collision will not be
announced and the internal loop back operation is disabled.
The Signal Quality Error test, however, is still operational if
enabled.

The MC34055 also provides the ability to test the collision
detect circuitry without disabling either of the data paths. By
pulling the SQE EN L pin low, a collision test is provided to
the collision detect circuitry immediately following the last
edge of a transmitted· 802.3 frame. The test verifies the
operability of the collision detect circuitry, operability is
announced by the assertion of the CTL H pin for a period
following a valid data transmission.

Jabber Detection

II

The transmit circuitry of the MC34055 has the ability to
monitor and shut down the differential driver in the event of a
jabber condition. If transmission activity ever exceeds 20 ms

Full Duplex Mode

Status Pins
The MC34055 has three status indicator pins capable of
sourcing or sinking enough current to support an external
LED. Status pin levels ("1" or "0") report the condition of the
transcei)ler. Table 2 shows the combinations and
significance.

MOTOROLA ANALOG IC.DEVICE.DATA

MC34055
APPLICATIONS INFORMATION
The MC34055 implements the physical layer of a
10BASE-T application of IEEE 802.3. It provides the
physical connection to the media (twisted pair) and the
services required by the MAC sublayer of the Data Link
Layer. Two interfaces are defined in the IEEE 802.3
specification of the physical layer; one is the MOl providing
connection to the twisted pair; and the other is the AUI
providing connection to the encoder/decoder function of the
Data Link Layer. While the MC34055 provides the connection
to the twisted pair, a CMOS and raised ECL interface is
provided instead of an AU/.
The MC34055 implements the twisted pair interface of the
physical layer in a 802.3 10BASE-T application but circuitry
must be added if an AUI is desired, (see Figure 10 for
suggested schematic). For example, an external MAU
application requires the AUI and a twisted pair interface. A
chip capable of realizing the AUI interface is the Texas
Instruments SN75ALS085. This Ie has an AUI interface and
another interface which is compatible with the MC34055. The
differential input of the 75ALS085 can be used for the
TX+ITX- terminals of the AU/. The differential drivers of the
75ASL085 can be used as the RX+/RX- and the
COL+/COL- terminals of the AU/. The other interface of the
75ALS085 then will interface to the MC34055 by three paths

MOTOROLA ANALOG IC DEVICE DATA

shown in the application suggestion. The application
accounts for all the inputs/outputs of an external MAU.
Embedded applications do not require a full AUI and a
MC10116 can be used to interface between the raised ECL
interfaces of the MC34055 and the AUI of existing
encoder/decoder chips. The MC10116 is a MECL 10k Triple
Line Receiver with typical propagation delay and rise and fall
times (20% to 80%) of 2.0 ns. Figure 11 shows the use of the
MC10116 with the MC34055 and the AMD 7992 SIA.
In a multi-port repeater, or hub, a port is required for each
DTE connected to the IEEE 802.3 network. This port consists
of two connections, one for the TX+ITX- pair and another for
the RX+/RX- pair. The repeater unit then multiplexes these
lines so that all of the stations are capable of transmitting to
or receiving from all the other stations on the network. This
establishes the need for a transceiver without an AUI
interface. If an AUI is present with each 10BASE-T
transceiver, chip count is increased because there is a
requirement to convert from balanced to unbalanced lines
before multiplexing.
An application suggestion for the use of the MC34055
used in a multipart repeater is shown in Figure 6. Here the
receive and transmit lines for the 10BASE-T transceivers are
multiplexed by the hub hardware.

Description
The MC34058/9 is a differential line driver designed to
comply with EIA-485 Standard for use in balanced digital
multipoint systems containing multiple drivers. The drivers
also comply with EIA-422-A and eelTT Recommendations
V.11 and X.27. Positive and negative current limiting of the
drivers meet the EIA-485 requirement for protection from
damage in the event that two or more drivers try to transmit
simultaneously on the same cable. Data rates in excess of
10 MBPS are possible, depending on the cable length and
cable characteristics. Only a single power supply, 5.0 V
± 10% is required.
Driver Inputs
The driver inputs and enable logic determine the state of
the outputs in accordance with Table 1. The driver inputs have

voltage is taken more than 0.5 V below ground or above Vec,
excessive currents will flow and proper operation of the
drivers will be affected. An open Pin is equivalent to a logic
high, but good design practices dictate that inputs should
never be left open. The inputs are TTL type and their
characteristics are unchanged by the state of the enable pins.
Driver Outputs
Each output (when active) will be a low or a high voltage,
depending on the input state and the load current (see
Tables 1, 2 and Figures 2 and 3). The graphs apply to each
driver, regardless of how many other drivers within the
package are supplying load current.

The outputs will be In a high impedance state when:
a) The Enable inputs are set according to Table 1;
b) The Junction temperature exceeds the trip point of the thermal shutdown circuit. When in this condition, the output's source and sink capability are shut off, and a
leakage current of less than 20 ~ will flow. Disabled outputs may be taken to any voltage between -7.0 V and 12 V without damage to Internal circuitry.
The drivers are protected from short circuits by two methods:
a) Current limiting is provided at each output, in both the source and sink direction, for shorts to any voltage w~hin the 12 Vto -7.0 V range, with respect to circuit
ground. The short circuit current will flow until the faun is removed, or until the thermal shutdown activates. The current limiting circuit has a negative temperature
ocefflcient and requires no resetting upon removal of the fauR condition.
b) A thermal shutdown circuit disables the outputs when the junction temperature reaches +150'C, ± 20'C. The thermal shutdown circuit has a hysteresis of - 12'C
to prevent oscillations. When this circuit activates, the output stage of each driver Is put into the high Impedance mode, thereby shutting ott the output currents.
However, the remainder of the internal circuitry remains biased and the outputs will become active once again as the IC cools down.

Receiver Inputs
The receiver inputs and enable logic determine the state of
the receiver outputs in accordance with Table 2. Each
receiver input pair has a nominal differential threshold of at
most 200 mV (Pin OAX with respect to OBX) and a common
mode voltage range of -7.0 V and 12 V must be maintained
for proper operation. A nominal hysteresis of 100 mV is
typical. The receiver input characteristics are shown in
Figure 8. When the inputs are in the high impedance state,
they remain capable of the common mode voltage range of
-7.0 V to 12 V.
Receiver Outputs
The receiver outputs are TTL type outputs and act in
accordance with Table 2.

Enable Logic
Each driver output is active when the Driver Enable input
is true according to Table 1. Each receiver output is active
when the Receiver Enable input is true according to Table 2.
The Enable inputs have a nominal threshold of 1.2 V and
their voltage must be kept within the range of 0 V and VCC for
proper operation. If the voltage is taken more than 0.5 V
below ground or above VCC, excessive currents will flow and
proper operation of the drivers will be affected. An open pin is
equivalent to a logic high, but good design practices dictate
that inputs should never be left open. The enable inputs are
TTL compatible. Since the same pins are used for driver input
and receiver output, care must be taken to make sure that
DEX and REX are not both enabled. This may result in
corruption of both the transmitted and received data.

APPLICATIONS
The MC34058/9 was designed to meet EIAlTIA-422 and
EIAlTIA-485 standards. EIAlTIA-422 specifies balanced
point-to-point transmission with the provision for multiple
receivers on the line. EIAlTIA-485 specifies balanced

point-to-point transmission and allows for multiple drivers
and receivers on the line. Refer to EIAITIA documents for
more details. Figure 9 shows a typical EIAlTIA-422 example.
Figure 10 shows a typical EIAlTIA-485 example.

EIAlTIA-422 specifications require the ability to drive at
least 10 receivers of input impedance of greater than or equal
to 4.0 K(1 plus the 100 (1 termination resistor. This protocol
was intended for unidirectional transmission. EIAlTIA-485 is
capable of bidirectional transmission by allowing multiple
drivers and receivers on the same twisted pair segment. The
loading of the twisted pair segment can be up to 32 Unit
Loads (U.L.) plus the two 120 (1 terminating resistors. The
U.L. definition is shown in Figure 11.

consisting of IOH , VOH ,IOL and VOL must be calculated for
each of the drivers and summed for the total power
dissipation estimate. The last term can be considered the
quiescent power required to keep the IC operational and is
measured with the drivers idle and unloaded. The VOH and
VOL terms can be determined from the output current
versus output voltage curves which provide driver output
characteristics.
Example 1 estimates thermal performance based on
current requirements.

(Ieads-to-board) combination in Figure 12. This path
provides the most effective way of removing heat from the
device provided that there is a viable temperature potential
(Le. heat sinking source) to conduct towards. However, if it is
not properly considered in the system design, the other
paths, (Rjcd + Rcdb) and (Rjcu + Rca) attain greater
importance and must be more carefully considered.

Board Temperature

An equivalent electrical circuit for the thermal model for the
MC3405819 package is shown in Figure 12. It is a simplified
model that shows the dominant means of heat transfer from
the thermally enhanced 48-ld package used for the
MC3405819. The model is a first order approximation and is
intended to emphasize the need to consider thermal issues
when designing the IC into any system. It is however
customary to use similar models and Equation 1 to estimate
device junction temperatures.
Equation 1 is the common means of using the thermal
resistance of a package to estimate junction temperature in a
particular system.

[1]
The term Sjx in Equation 1 is usually quoted as a 0ja value
in °ClWatt. However, since the 48-ld package for the
MC3405819 has been thermally enhanced to take advantage
of other heat sinking potentials, it must be modified. Sjx must
actually be considered a composite of all the heat transfer
paths from the Chip. That is, the three dominant and parallel
paths shown in Figure 12. Of those three paths, potentially
the most effective is the corner package leads. This is
because these corner leads have been attached to the flag
on which the silicon die is situated. These pins can be
connected to circuit board ground to provide a more efficient
conduction path for internal package heat. This path is
modeled as the Rjl (junction-to-Ieads) and Rib

7-114

where;
TJ= Junction Temperature
TA = Ambient Temperature
TS = Soard Temperature
PDISS = Device Power
and Sja = Total Thermal Resistance and is composed the
parallel combination of all the heat transfer paths from
the package.
While Equation 2 is still only a first order approximation of
the heat transfer paths of the MC34058/9, at least now it
includes consideration for the most effective heat transfer
path for the MC34058/9; the board to which the device is
soldered. The modified equation also better serves to
explain how external variables, namely the board and
ambient temperatur~s, affect the thermal performance of
the MC3405819.
Methods of removing heat via the flag connected pins can
be classified into two means; conduction and convection.
Radiation is omitted as the contribution is small compared to
the other means. Conduction is by far the best method to
draw heat away from the MC34058/9 package. This is best
accomplished by using a multilayer board with generous
ground plane. In this case, the flag connected pins can be
connected directly to the ground plane to maximize the heat
transfer from the package. Figure 13 shows the results of
thermal measurements of a board with an external ground
plane (the actual ground area was approximately 6 1/4 in2).
The thermal leads are connected to the board ground plane
per the recommended strategy.

Figure 14A on the other hand shows the result of a single
layer board without an internal ground plane. The graphs
show that even though there are radiators of substantial area
surrounding the package, substantial degredation of thermal
performance is evident (Figure 14B shows the layout used
for the measurements in Figure 14A). Comparing Figures 13
and 14A shows almost a 2:1 improvement for the strategy
involving the external ground plane.
It is clear from Figures 13, 14A and Example 1, that if an
application is to use all the device drivers, preparations to
assure adequate thermal performance of the system must
be taken.

If an extensive external ground plane is unavailable, and
only an internal ground plane is available, the thermal
performance of the device can still be improved by providing
thermal vias to connect the radiators to the internal ground
plane. Figure 15 shows a proposed scheme for thermal vias
(contact board manufactures for specifics about the thermal
performance of their products and possible enhancements).
The thermal resistance for this structure on 1.0 oz. Copper
connecting each of the four radiators to an internal ground
plane and provide an estimated thermal resistance of
approximately 5.0°CIW. The vias used in the estimate had
80 mil diameters, on 100 mil centers and a 1.0 mil copper
thickness.

28-Channel Inkjet Driver
The MC34156 is a 28-Channel Decoder/Driver intended to be used in
inkjet printer applications. By using sophisticated SMARTMOSTM technology, it
has been possible to combine low power CMOS inputs and logic and high
current, high voltage bipolar outputs capable of sustaining a maximum of 30 V.
A 4-t0--14 line decoder determines the selected output driver (n) in each
14-driver bank. Two independent output enable inputs (active low) then
provide the final decoding to activate 1- or 2--of-28 outputs (OUTAn and/or
OUTBn). The ac electrical characteristics of the drivers are tightly controlled
and thereby the energy of the device delivers to the inkjet print head. A Chip
Enable function is provided to lock out the drivers during system power up.
The 28 bipolar power outputs are open collector 30 V Darlington drivers
capable of sinking 500 mA at ambient temperatures up to 70°C. All driver
outputs are capable of withstanding a contact discharge of ±8.0 kV with the
IC biased.

Receive Enable Output: Indication of the presence of network activity, synchronous to
RCLK. In the standby mode, RENA is driven to the high impedance state.
Receive Data Output: Recovered data, synchronous to RCLK. Following a reset operation,
100 ms should be allowed before attempting to read data processed by the MC68160. This
delay is needed to insure that the receive phase locked loop is properly synchronized with
Incoming data. In the standby mode, RX is driven to the high impedance state.
Transmit Clock Output CMOSITTL Output: TCLK provides a sYl'(lmetrical clock signal at
10 MHz for reference timing of data to be encoded. In the standby mode, TCLK is driven to
the high impedance state.
Transmit Enable Input: Input signal synchronous to TCLK which enables data transmission
on the active port. An internal pull-down resistor is provided so that the input is low under no
connect conditions. (This resistor is removed in the standby mode). If TENA is asserted at
the conclusion of a reset operation, it must first be deasserted and then reasserjed before
data transmission can occur. In the standby mode, TENA is driven to the high impedance'
state.
Receive Clock Output: Recovered clock. In the standby mode, RCLK is driven to the high
impedance state.
Collision Output: In the AUI mode, indicates the presence of signals at the ACX+ and
ACX- terminals which meet threshold and pulse width requirements. In the TP mode,
indicates simultaneous transmit and receive activity, a heartbeat (SQI:: Test) signal was
generated, or the jabber timer has expired. In the standby mode, CLSN is driven. tq the high.

AUIINTERFACE

AUI Differential Transmit Outputs: This line pair is intended to operate into terminated
transmission lines. For TX signals meeting setup and hold time to TCLK when TENA is
previously asserted, Manchester encoded data is outputted at ATX+/-. When operating into a
78 Q terminated transmission line, signaling meets the required output levels and skew for
IEEE-802.3 drop cables. When the 10BASE-T port is automatically or manually selected,
the AUI outputs are driven to a low power standby state in which the outputs deliver a
balanced high state voltage.

Twisted Pair Differential Receiver Inputs: These inputs are connected to a receiver with
Smart Squelch capability which only allows differential receive data to pass as long as the
input amplitude is greater than a minimum signal threshold level and a specific pulse
sequence is received. This assures a good signal to noise ratio while the signal pair is active
by preventing crosstalk and impulse noise conditions from activating the receive function.

which the outputs deliver a balanced high state voltage. However, when the AUI port is
automatically selected, the 10BASE-Toutputs remain active.

Mode Select: The logic states applied to these pins select the appropriate interface for the
desired IEEE-802.3 controller or enable the standby mode. When the standby mode is
selected, the MC68160 power supply current is greatly reduced. Additionally, in the standby
mode, all of the controller inputs and outputs are driven to the high impedance state.

LOOP

I
TTL

Diagnostic Loopback: Asserting this function causes serial NRZ data at the TX input to be
Manchester encoded and then looped back through the Manchester decoder, appearing at
the RX output. This diagnostic loopback function operates independent of Twisted Pair (TP)
or Access Unit Interface (AUI) port connectivity or activity. Neither the TP port nor the AUI
port transmits data from the controller while diagnostic loopback is selected. Likewise, the
controller interface receives data neither from the TP nor the AUI receivers while in this
mode. The polarity fault detection and link integrity functions are not inhibited by the
diagnostic loopback mode. If otherwise enabled, they continue to function. If the twisted pair
port is selected, and TPSOEL is driven to the low logic state, a collision detect pulse is
delivered following each transmission to simulate the twisted pair SOE test.

APORT

I
TTL

Automatic Port Selection Enable: When high, MC68160 will automatically select the TP or
AUI port based on the presence or absence of valid link beats or frames at the TP receive
input. If the AUI port Is automatically selected, the MC68160 will continue to produce link
pulses for the TP port. Changing ports requires approximately 1.0 ms to allow the circuitry
for the new port to resume normal operation. The power consumption is minimized in the
circuitry associated with the unselected port.

Twisted Pair Signal Quality Error Test Enable: Forcing this pin low enables testing of the
internal TP collision detect circuitry after each transmit operation to the TP media. This
function provides a simulated collision to as much of the MC68160 collision detect circuitry
as possible without affecting the attached twisted pair channel. A normal SOE test results in
a high logic state at the CLSN controller interface pin which begins 6 to 16-bit times after the
last transition of a transmitted signal and continues for 5 to 15-bit times. (When the AUI port
is selected, SOE test signals are generated by the coaxial cable transceiver and delivered to
the controller via the MC68160 ACX+I- receive inputs)

TTL

Twisted Pair Automatic Polarity Correction Enable: When TPAPCE is high, automatic
polarity correction is enabled, and MC68160 will internally correct for a polarity fault on the
receive circuit. Additionally, when TPAPCE is high, the presence of a polarity fault is
indicated on TPPLR.

TPEN

I/O
TTL
(TTUCMOS)

Twisted Pair Port Enable: If APORT is low, TPEN is an input which determines whether the
AUI port (TPEN low) or TP port (TPEN high) will be manually selected. If the AUI port is
manually selected, the MC68160 will not produce link pulses for the TP port.
If APORT is high, TPEN is an output which will indicate which port has been automatically
selected by driving TPEN low (for AUI) or high (for TP). In its output mode TPEN can sink
10 mA in the low output state and source 10 mA in the high output state. (See Pin 9
Description.)
Changing ports requires approximately 1.0 ms to allow the circuitry for the new port to
resume normal operation. The power consumption is minimized in the cirCUitry aSSOCiated
with the unselected port. In the standby mode, this pin is driven to the high impedance state.

is selected. In the standby mode, this output is also driven to the high impedance state.
Twisted Pair Polarity Error Output: If TPAPCE is high and the wires connected to the
Twisted Pair Receiver Inputs (TPRX+, TPRX-) are reversed, TPPLR will be driven to the low

FUNCTIONAL DESCRIPTION
Introduction
The MC68160(EEST) was designed to perform the
physical connection to the Ethernet media. This is done
through two separate media dependent interfaces and aSIA
interface. The media dependent interfaces are the
Attachment Unit Interface(AUI) and the 10BASE-T Twisted
Pair(TP) port. The SIA interface is compatible with most
industry controllers and selected by three mode control pins.
Chip status is indicated by the condition of 6 status indicator
pins. All but one are open collector outputs.
If the EEST isn't receiving data, the controller may initiate
transmission. NRZ data from the communications controller
SIA interface is encoded by the MC68160 into Manchester
Code in preparation for transmission on the media. The data
is then applied to either the AUI or TP port. If the data was
transmitted using the 10BASE-T port, this data is also
looped back to the receive data interface SIA pins
connected to the controller. This allows detection of a
collision condition in the event that another station on the
media attempted transmission at the same time. After the
entire data frame has been transmitted, the EEST must
force the media idle signal. The idle signal frees the media
for other stations that have deferred transmission. If no
other transmissions are required the link enters an idle
state. During this idle state the 10BASE-T transmitter
issues idle pulses which communicates to the receiver
connected to the other side that the link is valid. If the

7-142

transmitter connected at the other end begins transmission,
the EEST will assert a receive enable signal, and forward
the received data to the controller.
Upon reception of data at the 10BASE-T port, the data is
screened for proper sequence and pulse width requirements.
If the preamble of the received frame meets the
requirements, the PLL locks onto the 64-bit preamble and
begins to decode the Manchester Code to NRZ code. This
code is then presented to the communications controller at
the receive data pins at the SIA interface. If data is received
at the AUI port, it is sent directly to the communications
controller via the SIA interface.
Data Transmission
To have properly encoded transmit data, the communications controller must be synchronized to TCLK.
Transmission to the 10BASE-T or AUI media occurs when
TENA is asserted and data is applied to the TX pin. Finally, to
signify transmission, the TXLED in will cycle on and off at a
100 ms period. Data transmission for EEST is accomplished
either over the 10BASE-T port or the AUI port. Both
connections to the media are made with industry standard
media interface components. The 10BASE-T interface
requires a filter and transformer, the AUI interface requires
only a transformer. The filter for the 1OBASE-T transmit
circuit will have to be chosen for each application.

MOTOROLA ANALOG IC DEVICE DATA

MC68160
If after approximately 40 ms after a TP or AUI transmission
has begun, the EEST is still transmitting, the TPJABB pin will
assert to signify a jabber condition. Also, the CLLED pin will
transition high and low alternately with a 100 ms period. The
transmit circuitry is, however, unaffected by the jabber
condition, so the communications controller has the
responsibility of monitoring and stopping transmission.
When transmission is complete, the transmit circuitry will
begin the end of transmit and decay to idle responses
necessary to meet requirements of the 802.3 standard for the
TP and AUI port.
Data Reception
Other than the case of being in Loop Back mode, data
reception to the RX pin of the EEST is initiated by signaling at
the RX+/- or AUI ARX+/- pins. If at the TP port, the data is
screened for validity by checking for sequence and pulse
width requirements, then passed to the decode and receive
circuitry. The RENA pin asserts and the data and
corresponding clock is passed to the communications
controller. After the frame has been transmitted, the
MC68160 detects the ending transmission and negates
RENA. If at the AUI port, the data is checked for proper pulse
width requirements before being passed to the decode
circuitry. If the data pulses are longer than at least 20 ns,
RENA gets asserted and the frame is decoded to RX with
and accompanying RCLK output.
Collision
Collision is the occurrence of simultaneous transmit
activity by two or more stations on the network. In the event of
collision, the data transfer paths are unaffected. If the
MC68160 is in the twisted pair mode, collision is detect by
simultaneous receive and transmit activity. If in the AUI
mode, collision is detected by activity on the ACX+/- pins. In
either case, if collision is detected, the CLSN pin will assert to
notify the communications controller.

MOTOROLA ANALOG IC DEVICE DATA

Jabber
The EEST has a jabber timer to detect the jabber condition.
In the event that the transmitting station continues to transmit
beyond the allowable transmit time, a jabber timer (40 ms) will
expire and assert the TPJABB pin to alert the communications
controller of the situation. The TPJABB pin can source or sink
up to 10 mA, and so, is capable of driving a status LED. In the
AUI mode, the pin is driven to high impedance since the
transceiver connected to the AUI port must alert the
communications controller of the jabber condition.
Full Duplex
A feature unique to the MC68160 is the Full Duplex mode.
In this mode the EEST is capable of transmitting and
receiving simultaneously. Collision conditions are not
announced and internal loop back is disabled. The remainder
of the EEST functionality remains unchanged from the
non-Full Duplex mode. Full Duplex mode is enabled by
asserting the TPFULDL pin.
Auto Port Selection
If the APORT pin is asserted, the MC68160 will
automatically select the TP or AUI port depending on the
presence of valid link beats or frames at the TP RX+/- pins. If
the AUI port is automatically selected by another transmitting
station or by setting TPEN low, the TP transmit port of the
EEST continues to transmit link beats to keep the link active.
Auto Polarity Selection
If the RX+ and the RX- wires happen to get reversed, the
MC68160 has the ability to automatically reverse the pins
intemally so that the received data is valid. In addition, an open
collector status pin (TPPLR) is driven low to indicate the fault.
In the AUI or reset mode this pin presents a high impedance.
Loop Back Mode
To test the transmit and receive circuitry without disturbing
the connected network, the EEST has a Loop Back mode.
Loop Back mode routes transmit data and clock to the
receive data and clock pins using as much of the transmit and
receive cirCUitry as possible. This gives a test of the
MC68160 Manchester encode and decode function.

MC75172B MC75174B
APPLICATIONS INFORMATION
Description
The MC75172B and MC75174B are differential line drivers
designed to comply with EIA-485 Standard (April 1983) for
use in balanced digital multipoint systems containing multiple
drivers. The drivers also comply with EIA-422-A and CCITT
Recommendations V.ll and X.27. The drivers meet the
EIA-485 requirement for protection from damage in the event
that two or more drivers attempt to transmit data
simultaneoulsy on the same cable. Data rates in excess of 10
MBPS are possible, depending on the cable length and cable
characteristics. A single power supply, 5.0 V, ±5%, is required
at a nominal current of 60 mA, plus load currents.
Outputs
Each output (when active) will be a low or a high voltage,
which depends on the input state and the load current (see
Table 1,2 and Figures 7 to 10). The graphs apply to each
driver, regardless of how many other drivers within the
package are supplying load current.

The two outputs of a driver are always complementary. A
"high" output can only source current out, while a "low" output
can only sink current (except for short circuit current - see
Figure 16).
The outputs will be in the high impedance mode when:
a) the Enable inputs are set according to Table 1 or 2;
b) VCC is less than 1.5 V;
c) the junction temperature exceeds the trip point of the
thermal shutdown circuit (see below). When in this
condition, the output's source and sink capability are
shut off, and only leakage currents will flow (see
Figures 13, 14). Disabled outputs may be taken to any
voltage between -7.0 V and 12 V without damage.

MOTOROLA ANALOG IC DEVICE DATA

The drivers are protected from short circuits by two
methods:
a) Current limiting is provided at each output, in both the
source and sink direction, for shorts to any voltage
within the range of 12V to-7.0V, with respect to circuit
ground (see Figure 16). The short circuit current will flow
until the fault is removed, or until the thermal shutdown
circuit activates (see below). The current limiting circuit
has a negative temperature coefficient and requires no
resetting upon removal of the fault condition.
b) A thermal shutdown circuit disables the outputs when
the junction temperature reaches 150°C, ±20°C. The
thermal shutdown circuit has a hysteresis of ~ 12°C to
prevent oscillations. When this circuit activates, the
output stage of each driver is put into the high
impedance mode, thereby shutting off the output
currents. The remainder of the internal circuitry remains
biased. The outputs will become active once again as
the IC cools down.
Driver Inputs
The driver inputs determine the state of the outputs in
accordance with Tables 1 and 2. The driver inputs have a
nominal threshold of 1.2 V, and their voltage must be kept
within the range of 0 V to VCC for proper operation. If the
voltage is taken more than 0.5 V below ground, excessive
currents will flow, and proper operation of the drivers will be
affected. An open pin is equivalent to a logic high, but good
design practices dictate that inputs should never be left open.
The characteristics of the driver inputs are shown in Figure
15. This graph is not affected by the state of the Enable pins.
Enable Logic
Each driver's outputs are active when the Enable inputs
(Pins 4 and 12) are true according to Tables 1 and 2.
The Enable inputs have a nominal threshold of 1.2 V and
their voltage must be kept within the range of 0 V to VCC for
proper operation. If the voltage is taken more than 0.5 V
below ground, excessive currents will flow, and proper
operation of the drivers will be affected. An open pin is
equivalent to a logic high, but good design practices dictate
that inputs should never be left open. The Enable input
characteristics are shown in Figure 15.
Operating Temperature Range
The minimum ambient operating temperature is listed as
-40°C to meet EIA-485 specifications, and O°C to meet
EIA-422-A specifications. The higher VOD required by
EIA-422-A is the reason for the narrower temperature range.

7-153

•

MC75172B MC75174B
The maximum ambient operating temperature (applicable
to both EIA-485 and EIA-422-A) is listed as 85°C. However,
a lower ambient may be required depending on system use
(i.e. specifically how many drivers within a package are used)
and at what current levels they are operating. The maximum
power which may be dissipated within the package is
determined by:
.
TJmax-TA
PO max = -"'R~'--!..!
aJA
where:

reducing the load current, reducing the ambient temperature,
and/or providing a heat sink.
System Requirements
EIA-485 requires each driver to be capable of transmitting
data differentially to at least 32 unit loads, plus an equivalent
DC termination resistance of 60n, over a common mode
voltage of -7.0 to 12 V. A unit load (U.L.), as defined by
EIA-485, is shown in Figure 17.
Figure 17. Unit Load Definition

RaJA = package thermal resistance (typical
70°C/Wfor the DIP package, 85°CIW for SOIC
package);
TJmax = max. operating junction
temperature, and
TA = ambient temperature.

Since the thermal shutdown feature has a trip point of
150°C, ±20°C, TJmax is selected to be 130°C. The power
dissipated within the package is calculated from:
PO
where:

II

= {[(VCC - VOH) • IOHl + VOL • IOL)) each driver
+ (VCC·ICC)
VCC = the supply voltage;
VOH, VOL are measured or estimated from
Figures 7 to 10;
ICC = the quiescent power supply current
(typical 60 mAl.

As indicated in the equation, the first term (in brackets)
must be calculated and summed for each of the four drivers,
while the last term is common to the entire package.
Example 1: TA = 25°C, IOL = IOH = 55 mA for each driver,
VCC = 5.0 V, DIP package. How many drivers per package
can be used?
Maximum allowable power dissipation is:

Since the power supply current of 60 mA dissipates
300 mW, that leaves 1.2 W (1.5 W - 0.3 W) for the drivers.
From Figures 7 and 9, VOL = 1.75 V, and VOH =3.85 V. The
power dissipated in each driver is:
{(5.0 - 3.85) • 0.055} + (1.75 • 0.055) = 160 mW.
Since each driver dissipates 160 mW, the four drivers per
package could be used in this application
Example2:TA=85°C, IOL=27.8mA, IOH=20mAforeach
driver, Vce = 5.0 V; SOIC package. How many drivers per
package can be used?
Maximum allowable power dissipation is:
PO max =

130°C - 85°C
85 0 C/W
=

0.53 W

Since the power supply current of 60 mA dissipates
300 mW, that leaves 230 mW (530 mW - 300 mW) for the
drivers. From Figures 8 and 10 (adjusted for VCC = 5.0 V),
VOL = 1.38 V, and VOH = 4.27 V. The power dissipated in
each driver is:
{(5.0 - 4.27) • 0.020} + (1.38 • 0.0278) = 53 mW

Reprinted from EIA-485, Electronic Industries Association,
Washington,DC.

A load current within the shaded regions represents an
impedance of less than one U.L., while a load current of a
magnitude outside the shaded area is greater than one U.L.
A system's total load is the sum of the unit load equivalents
of each receiver's input current, and each disabled driver's
output leakage current. The 60n termination resistance
mentioned above allows for two 120n terminating resistors.
Using the EIA-485 requirements (worst case limits), and
the graphs of Figures 7 and 9, it can be determined that the
maximum current an MC751728 or MC751748 driver will
source or sink is =65 mAo
System Example
An example of a typical EIA-485 system is shown in
Figure 18. In this example, it is assumed each receiver's input
characteristics correspond to 1.0 U.L. as defined in Figure 17.
Each "off' driver, with a maximum leakage of ±50 ~ over the
common mode range, presents a load of =0.06 U.L. The
total load for the active driver is therefore 8.3 unit loads, plus
the parallel combination of the two terminating resistors
(60n). It is up to the system software to control the driver
Enable pins to ensure that only one driver is active at any
time.
Termination Resistors
Transmission line theory states that, in order to preserve
the shape and integrity of a waveform traveling along a cable,
the cable must be terminated in an impedance equal to its
characteristic impedance. In a system such as that depicted
in Figure 18, in which data can travel in both directions, both
physical ends of the cable must be terminated. Stubs, leading
to each receiver and driver, should be as short as possible.
Leaving off the terminations will generally result in
reflections which can have amplitudes of several volts above
VCC or below ground. These overshoots and undershoots
can disrupt the driver and/or receiver operation, create false
data, and in some cases damage components on the bus.

Since each driver dissipates 53 mW, the use of all four
drivers in a package would be marginal. Options include

ULN2068

Quad 1.5 A Sinking High
Current Switch
The ULN2068 is a high-voltage, high-current quad Darlington switch array
designed for high current loads, both resistive and reactive, up to 300 W.
It is intended for interfacing between low level (TTL, DTL, LS and 5.0 V
CMOS) logic families and peripheral loads such as relays, solenoids, de and
stepping motors, multiplexer LED and incandescent displays, heaters, or other
high voltage, high current loads.
The Motorola ULN2068 is specified with minimum guaranteed breakdown
of 50 V and is 100% tested for safe area using an inductive load. It includes
integral transient suppression diodes. Use of a predriver stage reduces inpl.\t
current while still allowing the device to switch 1.5 Amps.
It is supplied in an improved 1&-Pin plastic DIP package with heat sink
contact tabs (Pins 4, 5,12 and 13). A copper alloy lead frame allows maximu
power dissipation using standard cooling techniques. The use of the co
tab lead frame facilitates attachment of a DIP heat sink while permi
use of standard layout and mounting practices.

Communication Circuits

In Brief ...
RF
Radio communication has greatly expanded its scope in the
past several years. Once dominated by public safety radio, the
30 to 1000 MHz spectrum is now packed with personal and low
cost business radio systems. The vast majority of this
equipment uses FM or FSK modulation and is targeted at short
range applications. From mobile phones and VHF marine
radios to garage door openers and radio controlled toys, these
new systems have become a part of our lifestyle. Motorola
Analog has focused on this technology, adding a wide array of
new products including complete receivers processed in our
exclusive 3.0 GHz MOSAIC® 1.5 process. New surface mount
packages for high density assembly are available for all of
these products, as well as a growing family of supporting
application notes and development kits.
Telephone & Voice/Data
Traditionally, an office environment has utilized two
distinctly separate wired communications systems:
telecommunications and data communications. Each had its
individual hardware components complement, and each
required its own independent transmission line system: twisted
wire pairs for Telecom and relatively high priced coaxial cable
for Datacom. But times have changed. Today, Telecom and
Datacom coexist comfortably on inexpensive twisted wire pairs
and use a significant number of components in common. This
has led to the development and enhancement of PBX (Private
Branch Exchanges) to the point where the long heralded
"office of the future," with simultaneous voice and data
communications capability at each station, is no longer of the
future at all. The capability is here today!
Motorola Semiconductor serves a wide range of
requirements for the voice/data marketplace. We offer both
CMOS and Analog technologies, each to its best advantage,
to upgrade the conventional analog voice systems and
establish new capabilities in digital communications. Early
products, such as the solid-state single-i:hip crosspoint
switch, the more recent monolithic Subscriber-LoopInterface Circuit (SLlC) , a single-i:hip Codee/Filter (MonoCircuit), the Universal Digital Loop Transceivers (UDLT),
basic rate ISDN (Integrated Services Digital NetWOrk), and
singl8-i:hip telephone circuits are just a few examples of
Motorola leadership in the voice/data area.

Case 648, 708, 751G, 776
The Mono--circuits perform the digitizing and restoration of
the analog signals. In addition to these important functions,
Motorola's family of pulse-code modulation mono-circuits
also provides the band-limiting filter functions - all on a single
monolithic CMOS chip with extremely low power dissipation.
The Mono-circuits require no external components. They
incorporate the bandpass filter required for anti aliasing and
60 Hz rejection, the A1D-O/A conversion functions for either
U.S. Mu-Law or European A-Law companding formats, the
low-pass filter required for reconstruction smoothing, an
on-board precision voltage reference, and a variety of options
that lend flexibility to circuit implementations. Unique features
of Motorola's Mono-circuit family include wide power supply
range (6.0 to 13 V), selectable on-board voltage reference
(2.5, 3.1, or 3.8 V), and TTL or CMOS 1/0 interface.
Motorola supplies three versions in this series. The
MC145503 and MC145505 are general-purpose devices in
16 pin packages designed to operate in digital telephone or
line card applications. The MC145502 is the full-feature
device that presents all of the options available on the chip.
This device is packaged in a 22 pin DIP and 28 pin chip carrier
package.

Case 648, 7510, 751G, 738
These per channel PCM Codee-Filters perform the voice
digitization and reconstruction as well as the band limiting and
smoothing required for PCM systems. They are designed to
operate in both synchronous and asynchronous applications
and contain an on-chip precision voltage reference. The
MC145554 (Mu-Law) and MC145557 (A-Law) are general
purpose devices that are offered in 16 pin packages. The
MC145564 (Mu-Law) and MC145567 (A-Law), offered in 20
pin packages, add the capability of analog loop-back and
push-pull power amplifiers with adjustable gain.
All four devices include the transmit bandpass and receive
lowpass filters on-chip, as well as active RC pre-filtering and
post-filtering. Fully differential analog circuit design assures
lowest noise. Performance is specified over the extended
temperature range of -40° to +85°C.

The MC145488 features two full-Quplex serial HDLC
channels with an on--chip Direct Memory Access (DMA)
controller. The DMA controller minimizes the number of
microprocessor interrupts from the communications
channels, freeing the microprocessor's resources for other
tasks. The DMA controller can access up to 64 kbytes of
memory, and transfers either 8-bit bytes or 18-bit words to or
from memory. The MC145488 DDLC is compatible with
Motorola's MC68000 and other microprocessors.
In a typical ISDN terminal application, one DDLC
communications channel supports the D--channel (LAPD)
while the other supports the B--channel (LAPB). While the
DDLC is ideally suited for ISDN applications, it can support
many other HDLC protocol applications as well.
Some of the powerful extras found on the DDLC include
automatic abort and retransmit of D--channel collisions in
SIT-interface applications, address recognition, automatic
recovery mechanisms for faulty frame correction, and several
system test modes. Address recognition provides a reduction
in the host microprocessor load by filtering data frames not
addressed to the host. The DDLC can compare either SAPI or
TEl fields of LAPD frames. For LAPD (Q.921) applications,
both A and B addresses may be checked.

MC145572EVK
U-Interface Transceiver Evaluation Kit
This kit provides the hardware and software to evaluate the
many configurations under which the MC145572EVK is able

two-wire U interface that extends from the customer premises
(NT1) to the switch line card (LT). The two halves ofthe board
can be physically and functionally separated, providing
independent NT1 and LT evaluation capability.
The kit provides the ability to interactively manipulate
status registers in the MC145572EVK U-Interface transceiver
or in the MC145474175 SIT-Interface transceiver with the aid
of an external terminal. The device can also be controlled

UDLTs utilize a 256 kilobaud Modified Differential Phase
Shift Keyed (MDPSK) burst modulation technique for
transmission to minimize radio frequency, electromagnetic,
and crosstalk interference. Implementation through CMOS
technology takes advantage of

increased reliability, and the proven capabilities to perform

The UDLT family of transceivers allows the use of existing
twisted-pair telephone lines (between conventional
telephones and a PBX) for the transmission of digital data.
With the UDLT, every voice-only telephone station in a PBX
system can be upgraded to a digital telephone station that
handles the complex voice/data communications with no
increase in cabling costs.
In implementing a UDLT-based system the AID to D/A
conversion function associated with each telset is relocated
from the PBX directly to the telsel. The SLiC (or its equivalent
circuit) is eliminated since its signaling information is
transmitted digitally between two UDLTs.
The UDLT master-slave system incorporates the
modulation/demodulation functions that permit data
communications over a distance up to 2 kilometers. It also
provides the sequence control that governs the exchange of
information between master and slave. Specifically, the master
resides on the PBX line card where it transmits and receives
data over the wire pair to the telset. The slave is located in the
telset and interfaces the mono-circuit to the wire pair. Data
transfer occurs in 1o-bit bursts (8 bits of data and 2 signaling
bits), with the master transmitting first, and the slave responding
In a synchronized half-duplex transmission formal.

OPERATIONS INFORMATION
The MC1496, a monolithic balanced modulator circuit, is
shown in Figure 23.
This circuit consists of an upper quad differential amplifier
driven by a standard differential amplifier with dual current
sources. The output collectors are cross-coupled so that
full-wave balanced multiplication of the two input voltages
occurs. That is, the output signal is a constant times the
product of the two input signals.
Mathematical analysis of linear ac signal multiplication
indicates that the output spectrum will consist of only the sum
and difference of the two input frequencies. Thus, the device
may be used as a balanced modulator, doubly balanced mixer,
product detector, frequency doubler, and other applications
requiring these particular output signal characteristics.
The lower differential amplifier has its emitters connected
to the package pins so that an external emitter resistance
may be used. Also, external load resistors are employed at
the device output.
Signal Levels
. The upper quad differential amplifier may be operated
either in a linear or a saturated mode. The lower differential
amplifier is operated in a linear mode for most applications.
For low-level operation at both input ports, the output
signal will contain sum and difference frequency components
Figure 23. Circuit Schematic

and have an amplitude which is a function of the product of
the input signal amplitudes.
For high-level operation at the carrier input port and linear
operation at the modulating signal port, the output signal will
contain sum and difference frequency components of the
modulating signal frequency and the fundamental and odd
harmonics of the carrier frequency. The output amplitude will
be a constant times the modulating signal amplitude. Any
amplitude variations in the carrier signal will not appear in the
output.
The linear Signal handling capabilities of a differential
amplifier are well defined. With no emitter degeneration, the
maximum input voltage for linear operation is approximately
25 mV peak. Since the upper differential amplifier has its
emitters internally connected, this voltage applies to the
carrier input port for all conditions.
Since the lower differential amplifier has provisions for an
external emitter resistance, its linear signal handling range
may be adjusted by the user. The maximum input voltage for
linear operation may be approximated from the following
expression:
V =(15) (RE) volts peak.
This expression may be used to compute the minimum
value of RE for a given input voltage amplitude.

The gain from the modulating Signal input port to the
output is the MC1496 gain parameter which is most often of
interest to the designer. This gain has significance only when
the lower differential amplifier is operated in a linear mode,
but this includes most applications of the device.
As previously mentioned, the upper quad differential
amplifier may be operated either in a linear or a saturated
mode. Approximate gain expressions have been developed
for the MC1496 for a low-level modulating signal input and
the following carrier input conditions:
1) Low-level dc
2) High-level dc
3) Low-level ac
4) High-level ac
These gains are summarized in Figure 25, along with the
frequency components contained in the output signal.

APPLICATIONS INFORMATION
Double sideband suppressed carrier modulation is the
basic application of the MC1496. The suggested circuit for
this application is shown on the front page of this data sheet.
In some applications, it may be necessary to operate the
MC1496 with a single dc supply voltage instead of dual
supplies. Figure 26 shows a balanced modulator designed
for operation with a Single 12 Vdc supply. Performance of this
circuit is similar to that of the dual supply modulator.
AM Modulator
The circuit shown in Figure 27 may be used as an
amplitude modulator with a minor modification.

8-52

All that is required to shift from suppressed carrier to AM
operation is to adjust the carrier null potentiometer for the
proper amount of carrier insertion in the output signal.
However, the suppressed carrier null circuitry as shown in
Figure 27 does not have sufficient adjustment range.
Therefore, the modulator may be modified for AM operation
by changing two resistor values in the null circuit as shown in
Figure 28.
Product Detector
The MC1496 makes an excellent SSB product detector
(see Figure 29).
This product detector has a sensitivity of 3.0 microvolts
and a dynamic range of 90 dB when operating at an
intermediate frequency of 9.0 MHz.
The detector is broadband for the entire high frequency
range. For operation at very low intermediate frequencies
down to 50 kHz the 0.1 I1F capaCitors on Pins 8 and 10
should be increased to 1.0 11F. Also, the output filter at Pin 12
can be tailored to a specific intermediate frequency and audio
amplifier input impedance.
As in all applications of the MC1496, the emitter resistance
between Pins 2 and 3 may be increased or decreased to
adjust circuit gain, sensitivity, and dynamic range.
This circuit may also be used as an AM detector by
introducing carrier signal at the carrier input and an AM signal
at the SSB input.
The carrier signal may be derived from the intermediate
frequency signal or generated locally. The carrier signal may
be introduced with or without modulation, provided its level is
sufficiently high to saturate the upper quad differential

MC1496,B
amplifier. If the carrier signal is modulated, a 300 mVrms
input level is recommended.
Doubly Balanced Mixer
The MC1496 may be used as a doubly balanced mixer
with either broadband or tuned narrow band input and output
networks.
The local oscillator signal is introduced at the carrier input
port with a recommended amplitude of 100 mVrms.
Figure 30 shows a mixer with a broadband input and a
tuned output.
Frequency Doubler
The MC1496 will operate as a frequency doubler by
introducing the same frequency at both input ports.

Figures 31 and 32 show a broadband frequency doubler
and a tuned output very high frequency (VHF) doubler,
respectively.
Phase Detection and FM Detection
The MC1496 will function as a phase detector. High-level
input signals are introduced at both inputs. When both inputs
are at the same frequency the MC1496 will deliver an output
which is a function of the phase difference between the two
input signals.
An FM detector may be constructed by using the phase
detector principle. A tuned circuit is added at one of the inputs
to cause the two input signals to vary in phase as a function
of frequency. The MC1496 will then provide an output which
is a function of the input signal frequency.

CIRCUIT DESCRIPTION
The MC3335 is a complete FM narrowband receiver from
antenna input to audio preamp output. The low voltage dual
conversion design yields low power drain, excellent
sensitivity and good image rejection in narrowband voice and
data link applications.
In the typical application diagram, the' first mixer amplifies
the signal and converts the RF input to 10.7 MHz. This IF
signal is filtered externally and fed into the second mixer,
which further amplifies the signal and converts it to a 455 kHz
IF signal. After external bandpass filtering, the low IF is fed
into the limiting amplifier and detection circuitry. The audio is
recovered using a conventional quadrature detector.
Twice-IF filtering is provided internally.
The input signal level is monitored by meter drive circuitry
which detects the amount of limiting in the limiting amplifier.
The voltage at the meter drive pin determines the state of the
carrier detect output which is active low.

APPLICATIONS INFORMATION
The first local oscillator can be run using a free running LC
tank, as a VCO using PLL synthesis, or driven from an
external crystal oscillator. At higher VCC values (6.0 to
7.0 V), it has been run to 170 MHz. The second local
oscillator is a common base Colpitts type which is typically
run at 10.245 MHz under crystal control.
The mixers are doubly balanced to reduce spurious
responses. The first and second mixers have conversion
gains of 18 dB and 22 dB (typical), respectively. Mixer gain is
stable with respect to supply voltage. For both conversions,
the mixer impedances and pin layout are designed to allow
the user to employ low cost, readily available ceramic filters.
Overall sensitivity is shown in Figure 5. The input level for
20 dB (S + N)/N is 1.3 !LV using the two-pole post-detection
filter as demonstrated.

MOTOROLA ANALOG IC DEVICE DATA

Following the first mixer, a 10.7 MHz ceramic bandpass
filter is recommended. The 10.7 MHz filtered signal is then
fed into one second mixer input pin, the other input pin being
connected to VCC. Pin 5 (VCC) is treated as a common point
for emitter-driven signals.
The 455 kHz IF is typically filtered using a ceramic
bandpass filter, then fed into the limiter input pin. The limiter
has 10 !LV sensitivity for -3.0 dB limiting, flat to 1.0 MHz.
The output of the limiter is internally connected to the
quadrature detector, including a quadrature capacitor. A
parallel LC tank is needed externally from Pin 11 to VCC.
A 39 k.Q shunt resistance is included which determines the
peak separation of the quadrature detector; a smaller value
will increase the spacing and linearity but decrease
recovered audio and sensitivity.
A data shaping circuit is available and can be coupled to
the recovered audio output of Pin 12. The circuit is a
comparator which is designed to detect zero crossings of
FSK modulation. Data rates of up to 35000 baud are
detectable using the typical application. Hysteresis is
available by connecting a high-valued resistor from Pin 13 to
Pin 14. Values below 120 kn are not recommended as the
input signal cannot overcome the hysteresis.
The meter drive circuitry detects input Signal level by
monitoring the limiting of the limiting amplifier stages.
Figure 2 shows the unloaded current at Pin 9 versus input
power. The meter drive current can be used directly (RSSI)
or can be used to trip the carrier detect circuit at a specified
input power. To do this, pick an RF trip level in dBm. Read the
corresponding current from Figure 2 and pick a resistor such
that:
R9 =0.64 Vdc / 19
Hysteresis is available by connecting a high-valued
resistor RH between Pin 9 and 10. The formula is:
Hysteresis =VCcI(RH x 10- 7) dB

GENERAL DESCRIPTION
This device is intended for single and double conversion
VHF receiver systems, primarily for FSK data transmission
up to 500 K baud (250 kHz). It contains an OSCillator, mixer,
limiting IF, quadrature detector, signal strength meter drive,
and data shaping amplifier.
The oscillator is a common base CCllpitis type which can
be crystal controlled, as shown in Figure 1, or L-G controlled
as shown in the other figures. At higher VCC, it" has been
operated as high as 200 MHz. A mixer/oscillator voltage gain
of 2 up to approximately 150 MHz, is readily achievable.
The mixer functions well from an input signal of
10 j.tVrms, below which the squelch is unpredictable, up to
about 10 mVrms, before any evidence of overload.
Operation up to 1.0 Vrms input is permitted, but non-linearity
of the meter output is incurred, and some oscillator pulling is
suspected. The AM rejection above 10 mVrms is degraded.
The limiting IF is a high frequency type, capable of being
operated up to 50 MHz. It is expected to be used at 10.7 MHz
in most cases, due to the availability of standard ceramic
resonators. The quadrature detector is internally coupled to
the IF, and a 5.0 pF quadrature capaCitor is internally
provided. The -3dB limiting sensitivity of the IF itself is
approximately 50 j.tV (at Pin 7), and the IF can accept signals
up to 1.0 Vrms without distortion or change of detector
quiescent dc level.
The IF is unusual in that each of the last 5 stages of the
6 state limiter contains a signal strength sensitive, current
sinking device. These are parallel connected and buffered to
produce a signal strength meter drive which is fairly linear for
IF input signals of 10 j.tV to 100 mVrms (see Figure 4).
A simple squelch arrangement is provided whereby the
meter current flowing through the meter load resistance flips
a comparator at about 0.8 Vdc above ground. The signal
strength at which this occurs can be adjusted by changing
the meter load resistor. The comparator (+) input and output
are available to permit control of hysteresis. Good positive

8-68

action can be obtained for IF input signals of above 30
j.tVrms. The 130 k.Q resistor shown in the test circuit provides
a small amount of hysteresis. Its connection between the
3.3 k resistor to ground and the 3.0 k pot, permits adjustment
of squelch level without changing the amount of hysteresis.
The squelch is internally connected to both the
quadrature detector and the data shapero The quadrature
detector output, when squelched, goes to a dc level
approximately equal to the zero signal level unsquelched.
The squelch causes the data shaper to produce a high (VCC)
output.
The data shaper is a complete "floating" comparator,
with back to back diodes across its inputs. The output of the
quadrature detector can be fed directly to either input of this
amplifier to produce an output that is either at VCC or VEE,
depending upon the received frequency. The impedance of
the biasing can be varied to produce an amplifier which
"follows" frequency detuning to some degree, to prevent data
pulse width changes.
When the data shaper is driven directly from the
demodulator output, Pin 13, there may be distortion at Pin 13
due to the diodes, but this is not important in the data
application. A useful note in relating highllow input frequency
to logic state: low IF frequency corresponds to low
demodulator output. If the oscillator is above the incoming
RF frequency, then high RF frequency will produce a logic
low (input to (+) input of Data Shaper as shown in Figures 1
and 2).
APPLICATION NOTES
The MC3356 is a high frequency/high gain receiver that
requires following certain layout techniques in designing a
stable circuit configuration. The objective is to minimize or
eliminate, if possible, any unwanted feedback.

APPLICATION NOTES (continued)
Shielding, which includes the placement of input and
output components, is important in minimizing electrostatic or
electromagnetic coupling. The MC3356 has its pin
connections such that the circuit designer can place the
critical input and output circuits on opposite ends of the chip.
Shielding is normally required for inductors in tuned circuits.
The MC3356 has a separate VCC and ground for the RF
and IF sections which allows good external circuit isolation by
minimizing common ground paths.
Note that the circuits of Figures 1 and 2 have RF,
Oscillator, and IF circuits predominantly referenced to the
plus supply rails. Figure 5, on the other hand, shows a
suitable means of ground referencing. The two methods
produce identical results when carefully executed. It is
important to treat Pin 19 as a ground node for either
approach. The RF input should be "grounded" to Pin 1 and
then the input and the mixer/oscillator grounds (or RF Vce
bypasses) should be connected by a low inductance path to
Pin 19. IF and detector sections should also have their

MOTOROLA ANALOG IC DEVICE DATA

bypasses returned by a separate path to Pin 19. VCC and
RF VCC can be decoupled to minimize feedback, although
the configuration of Figure 2 shows a successful
implementation on a common 5.0 V supply. Once again, the
message is: define a supply node and a ground node and
return each section to those nodes by separate, low
impedance paths.
The test circuit of Figure 2 has a 3 dB limiting level of
30 iJ,V which can be lowered 6 db by a 1:2 untuned
transformer at the input as shown in Figures 5 and 6. For
applications that require additional sensitivity, an RF amplifier
can be added, but with no greater than 20 db gain. This will
give a 2.0 to 2.5 iJ,V sensitivity and any additional gain will
reduce receiver dynamic range without improving its
sensitivity. Although the test circuit operates at 5.0 V, the
mixer/oscillator optimum performance is at 8.0 V to 12 V. A
minimum of 8.0 V is recommended in high frequency
applications (above 150 MHz), or in PLL applications where
the oscillator drives a prescaler.

Depending on the external circuit, inverted or
noninverted data is available at Pin 18. Inverted data makes
the higher frequency in the FSK signal a "one" when the local
oscillator is above the incoming RF. Figure 5 schematic
shows the comparator with hysteresis. In this circuit the dc
reference voltage at Pin 17 is about the same as the
demodulated output voltage (Pin 13) when no signal is
present. This type circuit is preferred for systems where the
data rates can drop to zero. Some systems have a low
frequency limit on the data rate, such as systems using the
MC3850 ACIA that has a start or stop bit. This defines the
low frequency limit that can appear in the data stream.

8-70

Figure 5 circuit can then be changed to a circuit configuration
as shown in Figure 6. In Figure 6 the reference voltage for
the comparator is derived from the demodulator output
through a low pass circuit where 't is much lower than the
lowest frequency data rate. This and similar circuits will
compensate for small tuning changes (or drift) in the
quadrature detector.
Squelch status (Pin 15) goes high (squelch off) when the
input signal becomes greater than some preset level set by
the resistance between Pin 14 and ground. Hysteresis is
added to the circuit externally by the resistance from Pin 14to
Pin 15.

CIRCUIT DESCRIPTION
The MC3357 is a low power FM IF circuit designed
primarily for use in voice communication scanning receivers.
The mixer-oscillator combination converts the input
frequency (e.g., 10.7 MHz) down to 455 kHz, where, after
external bandpass filtering, most of the amplification is done.
The audio is recovered using a conventional quadrature FM
detector. The absence of an input Signal is indicated by the
presence of noise above the desired audio frequencies. This
"noise band" is monitored by an active filter and a detector. A
squelch trigger circuit indicates the presence of a noise (or a
tone) by an output which can be used to control scanning. At
the same time, an internal switch is operated which can be
used to mute the audio.
The oscillator is an internally-biased Colpitts type with the
collector, base, and emitter connections at Pins 4, 1, and 2
respectively. A crystal can be used in place of the usual coil.
The mixer is doubly-balanced to reduce spurious
responses. The input impedance at Pin 16 is set by a 3.0 kQ
internal biasing resistor and has low capacitance, allowing
the circuit to be preceded by a crystal filter. The collector
output at Pin 3 must be dc connected to B +, below which it
can swing 0.5 V.
After suitable bandpass filtering (ceramic or LC), the signal
goes to the input of a five-stage limiter at Pin 5. The output of
the limiter at Pin 7 drives a multiplier, both internally directly,

8-74

and extemally through a quadrature coil, to detect the FM. The
output at Pin 7 is also used to supply dc feedback to Pin 5. The
other side of the first limiter stage is decoupled at Pin 6.
The recovered audio is partially filtered, then buffered,
giving an impedance of around 400 n at Pin 9. The signal still
requires de-emphasis, volume control and further
amplification before driving a loudspeaker.
A simple inverting op amp is provided with an output at Pin
11 providing dc bias (externally) to the input at Pin 10 which is
referred internally to 2.0 V. A filter can be made with external
impedance elements to discriminate between frequencies.
With an external AM detector, the filtered audio signal can be
checked for the presence of noise above the normal audio
band, or a tone signal. This information is applied to Pin 12.
An external positive bias to Pin 12 sets up the squelch
trigger circuit such that Pin 13 is low at an impedance level of
around 60 kn, and the audio mute (Pin 14) is open circuit. If
Pin 12 is pulled down to 0.7 V by the noise or tone detector,
Pin 13 will rise to approximately 0.5 Vdc below supply where
it can support a load current of around 500 I-!A and Pin 14 is
internally short-circuited to ground. There is 100 mV of
hysteresis at Pin 12 to prevent jitter. Audio muting is
accomplished by connecting Pin 14 to a high-impedance
ground-reference point in the audio path between Pin 9 and
the audio amplifier.

MC3359

Low Power Narrowband FM IF
· .. includes oscillator, mixer, limitin'g amplifier, AFC, quadrature
discriminator, op/amp, squelch, scan control, and mute switch. The MC3359
is designed to detect narrowband FM signals using a 455 kHz ceramic filter
for use in FM dual conversion communications equipment. The MC3359 is
similar to the MC3357 except that the MC3359 has an additional limiting IF
stage, an, AFC output, and an opposite polarity Broadcast Detector. The
MC3359 also requires fewer external parts. For low cost applications
requiring VCC below 6.0 V, the MC3361 BP,BD are recommended. For
. applications requiring a fixed, tuned, ceramic quadrature resonator, use the
MC3357. For applications requiring dual conversion and RSSI, refer to these
devices; MC3335, MC3362 and MC3363.
• Low Drain Current: 3.6 mA (Typical) @ Vee

MC3359
CIRCUIT DESCRIPTION
The MC3359 is a low-power FM IF circuit designed
primarily for use in voice-communication scanning receivers.
It is also finding a place in narrowband data links.
In the typical application (Figure 1), the mixer-oscillator
combination converts the input frequency (10.7 MHz) down
to 455 kHz, where, after external bandpass filtering, most of
the amplification is done. The audio is recovered using a
conventional quadrature FM detector. The absence of an
input signal is indicated by the presence of noise above the
desired audio frequencies. This "noise band" is monitored by
an active filter and a detector. A squelch-trigger circuit
indicates the presence of noise (or a tone) by an output which
can be used to control scanning. At the same time, an
internal switch is operated which can be used to mute the
audio.
APPLICATIONS INFORMATION
The oscillator is an internally biased Colpitts type with the
collector, base, and emitter connections at Pin 4, 1 and 2,
respectively. The crystal is used in fundamental mode,
calibrated for parallel resonance at 32 pF load capacitance.
In theory this means that the two capacitors in series should
be 32 pF, but in fact much larger values do not significantly
affect the oscillator frequency, and provide higher oscillator
output.
The oscillator can also be used in the conventional UC
Colpitts configuration without loss of mixer conversion gain.
This oscillator is, of course, much more sensitive to voltage
and temperature as shown in Figure 12. Guidelines for
choosing Land C values are given in Figure 14.
The mixer is doubly balanced to reduce spurious
responses. The mixer measurements of Figure 4 and 6 were
made using an external 50 0 source and the internal 1.8 k at
Pin 3. Voltage gain curves at several VCC voltages are shown
in Figure 4. The Third Order Intercept curves of Figure 6 are
shown using the conventional dBm scales. Measured power
gain (with the 50 0 input) is approximately 18 dB but the
useful gain is much higher because the mixer input
impedance is over 3 kO. Most applications will use a 330 0
10.7 MHz crystal filter ahead of the mixer. For higher
frequencies, the relative mixer gain is given in Figure 8.
Following the mixer, a ceramic bandpass filter is
recommended. The 455 kHz types come in bandwidths from
± 2 kHz to ± 15 kHz and have input and output impedances of
1.5 k to 2.0 k. For this reason, the Pin 5 input to the 6 stage
limiting IF has an internal 1.8 k resistor. The IF has a 3 dB

MOTOROLA ANALOG IC DEVICE DATA

limiting sensitivity of approximately 100 IlV at Pin 5 and a
useful frequency range of about 5 MHz as shown in Figure 5.
The frequency limitation is due to the high resistance values
in the IF, which were necessary to meet the low power
requirement. The output of the limiter is internally connected
to the quadrature detector, including the 10 pF quadrature
capacitor. Only a parallel UC is needed externally from Pin 8
to VCC. A shunt resistance can be added to widen the peak
separation of the quadrature detector.
The detector output is amplified and buffered to the audio
output, Pin 10, which has an output impedance of
approximately 300 o. Pin 9 provides a high impedance (50 k)
point in the output amplifier for application of a filter or
de-emphasis capacitor. Pin 11 is the AFC output, with high
gain and high output impedance (1 M). If not needed, it
should be grounded, or it can be connected to Pin 9 to double
the recovered audio. The detector and AFC responses are
shown in Figure 7.
Overall performance of the MC3359 from mixer input to
audio output is shown in Figure 9 and 10. The MC3359 can
also be operated in "single conversion" equipment; i.e., the
mixer can be used as a 455 kHz amplifier. The oscillator is
disabled by connecting Pin 1 to Pin 2. In this mode, the
overall performance is identical to the 10.7 MHz results of
Figure 9.
A simple inverting op amp is provided with an output at
Pin 13 providing dc bias (externally) to the input at Pin 12,
which is referred internally to 2.0 V. A filter can be made with
external impedance elements to discriminate between
frequencies. With an external AM detector, the filtered audio
signal can be checked for the presence of either noise above
the normal audio, or a tone signal.
The open loop response of this op amp is given in
Figure13. Bandpass filter design information is provided in
Figure 15.
A low bias to Pin 14 sets up the squelch-trigger circuit so
that Pin 15 is high, a source of at least 2.0 mA, and the audio
mute (Pin 16) is open--circuit. If Pin 14 is raised to 0.7 V by
the noise or tone detector, Pin 15 becomes open circuit and
Pin 16 is internally short circuited to ground. There is no
hysteresis. Audio muting is accomplished by connecting Pin
16 to a high-impedance ground-reference point in the audio
path between Pin 10 and the audio amplifier. No dc voltage is
needed, in fact it is not desirable because audio "thump"
would result during the muting function. Signal swing greater
than 0.7 V below ground on Pin 16 should be avoided.

CIRCUIT DESCRIPTION
The MC3362 is a complete FM narrowband receiver from
antenna input to audio preamp output. The low voltage dual
conversion design yields low power drain, excellent
sensitivity and good image rejection in narrowband voice and
data link applications.
In the typical application (Figure 1), the first mixer
amplifies the signal and converts the RF input to 10.7 MHz.
This IF signal is filtered externally and fed into the second
mixer, which further amplifies the signal and converts it to a
455 kHz IF signal. After external bandpass filtering, the low IF
is fed into the limiting amplifier and detection circuitry. The
audio is recovered using a conventional quadrature detector.
Twice-IF filtering is provided internally:
The input signal level is monitored by meter drive circuitry
which detects the amount of limiting in the limiting amplifier.
The voltage at the meter drive pin determines the state of the
carrier detect output, which is active low.

APPLICATIONS INFORMATION
The first local oscillator can be run using a free-running
LC tank, as a VCO using PLL synthesis, or driven from an
external crystal oscillator. It has been run to 190 MHz: A
buffered output is available at Pin 20. The second local
'. oscillator is a common base Colpitts type which is typically
run at 10.245 MHz under crystal control. A buffered output is
available at Pin 2. Pins 2 and 3 are interchangeable.
The mixers are doubly balanced to reduce spurious
responses. The first and second mixers have conversion
gains of 18 dB and 22 dB (typical), respectively, as seen in
Figure 6. Mixer gain is stable with respect to supply voltage.
For both conversions, the mixer impedal'\ces and pin layout
are designed to allow the user to employ low cost, readily
available ceramic filters. Overall sensitivity and AM rejection
are shown in Figure 7: The input level for 20 dB (8 + N)/N is
0.71LV using the two-pole post-detection filter pictured.

'If the first local oscillator (Pins 21 and/or 22) is driven from a
strong external source (100 mVrms). the mixer can be used to
over 450 MHz.

8-86

MOTOROLA ANALOG IC DEVICE DATA

MC3362
Following the first mixer, a 10.7 MHz ceramic band-pass
filter is recommended. The 10.7 MHz filtered signal is then
fed into one second mixer input pin, the other input pin being
connected to Vee. Pin 6 (Vee) is treated as a common point
for emitter-driven signals.
The 455 kHz IF is typically filtered using a ceramic
bandpass filter then fed into the limiter input pin. The limiter
has 10 !LV sensitivity for - 3.0 dB limiting, flat to 1.0 MHz.
The output of the limiter is internally connected to the
quadrature detector, including a quadrature capacitor. A
parallel Le tank is needed externally from Pin 12 to Vee. A 39
kQ shunt resistance is included which determines the peak
separation of the quadrature detector; a smaller value will
increase the spacing and linearity but decrease recovered
audio and sensitivity.
A data shaping circuit is available and can be coupled to
the recovered audio output of Pin 13. The circuit is a
comparator which is designed to detect zero crossings of

FSK modulation. Data rates are typically limited to 1200 baud
to ensure data integrity and avoid adjacent channel "splatter."
Hysteresis is available by connecting a high valued resistor
from Pin 15 to Pin 14. Values below 120 kn are not
recommended as the input signal cannot overcome the
hysteresis.
The meter drive circuitry detects input signal level by
monitoring the limiting amplifier stages. Figure 4 shows the
unloaded current at Pin 10 versus input power. The meter
drive current can be used directly (RSSI) or can be used to
trip the carrier detect circuit at a specified input power. To do
this, pick an RF trip level in dBm. Read the corresponding
current from Figure 4 and pick a resistor such that:
R10 "'" 0.64 Vdc / 110
Hysteresis is available by connecting a high valued resistor
RH between Pins 10 and 11. The formula is:
Hysteresis

=Vecl(RH x 10 - 7) dB

CIRCUIT DESCRIPTION
The MC3363 is a complete FM narrowband receiver from
RF amplifier to audio preamp output. The low voltage dual
conversion design yields low power drain, excellent
sensitivity and good image rejection in narrowband voice and
data link applications.
In the typical application, the input RF signal is amplified
by the RF transistor and then the first mixer amplifies the
signal and converts the RF input to 10.7 MHz. This IF signal
is filtered externally and fed into the second mixer, which
further amplifies the signal and converts it to a 455 kHz IF
signal. After external bandpass filtering, the low IF is fed into
the limiting amplifier and detection circuitry. The audio is
recovered using a conventional quadrature detector.
Twice-IF filtering is provided internally.
The input signal level is monitored by meter drive circuitry
which detects the amount of limiting in the limiting amplifier.
The voltage at the meter drive pin determines the state of the
carrier detect output, which is active low.

APPLICATIONS INFORMATION
The first local oscillator is designed to serve as the VCO in
a Pll frequency synthesized receiver. The MC3363 can
operate together with the MC145166n to provide a two-chip
ten--channel frequency synthesized receiver in the 46/49
cordless telephone band. The MC3363 can also be used with
the MC14515X series of CMOS Pll synthesizers and
MC120XX series of ECl prescalers in VHF frequency
synthesized applications to 200 MHz.
For single channel applications the first local oscillator can
be crystal controlled. The circuit of Figure 4 has been used
successfully up to 60 MHz. For higher frequencies an
external oscillator signal can be injected into Pins 25 and/or
26 - a level of approximately 100 mVrms is recommended.
The first mixer's transfer characteristic is essentially flat to
450 MHz when this approach is used (keeping a constant
10.7 MHz IF frequency). The second local oscillator is a
Colpitts type which is typically run at 10.245 MHz under
crystal control.
The mixers are doubly balanced to reduce spurious
responses. The first and second mixers have conversion
gains of 18 dB and 21 dB (typical), respectively. Mixer gain is
stable with respect to supply voltage. For both conversions,
the mixer impedances and pin layout are designed to allow
the user to employ low cost, readily available ceramic filters.
Following the first mixer, a 10.7 MHz ceramic bandpass
filter is recommended. The 10.7 MHz filtered signal is then
fed into the second mixer input Pin 21, the other input Pin 22
being connected to VCC.
The 455 kHz IF is filtered by a ceramic narrow bandpass
filter then fed into the limiter input Pin 9. The limiter has 1011V
sensitivity for -3.0 dB limiting, flat to 1.0 MHz.
The output of the limiter is internally connected to the
quadrature detector, including a quadrature capacitor. A

parallel lC tank is needed externally from Pin 14 to VCC. A 68
kO shunt resistance is included which determines the peak
separation of the quadrature detector; a smaller value will
lower the Q and expand the deviation range and linearity, but
decrease recovered audio and sensitivity.
A data shaping circuit is available and can be coupled to
the recovered audio output of Pin 16. The circuit is a
comparator which is designed to detect zero crossings of
FSK modulation. Data rates of up to 35000 baud are
detectable using the comparator. Best sensitivity is obtained
when data rates are limited to 1200 baud maximum.
Hysteresis is available by connecting a high-valued resistor
from Pin 17 to Pin 18. Values below 120 kO are not
recommended as the input signal cannot overcome the
hysteresis.
The meter drive circuitry detects input signal level by
monitoring the limiting of the limiting amplifier stages.
Figure 5 shows the unloaded current at Pin 12 versus input
power. The meter drive current can used directly (RSSI) or
can be used to trip the carrier detect circuit at a specified
input power.
A muting op amp is provided and can be triggered by the
carrier detect output (Pin 13). This provides a carrier level
triggered squelch circuit which is activated when the RF input
at the desired input frequency falls below a present level. The
level at which this occurs is determined by the resistor placed
between the meter drive output (Pin 12) and VCC. Values
between 80-130 kO are recommended. This type of squelch
is pictured in Figures 3 and 4.
Hysteresis is available by connecting a high-valued
resistor Rh between Pins 12 and 13. The formula is:
Hyst

= VCC/ (Rh x 10- 7) dB

The meter drive can also be used directly to drive a meter
or to provide AGC. A current to voltage converter or other
linear buffer will be needed for this application.
A second possible application of the op amp would be in a
noise triggered squelch circuit, similar to that used with the
MC3357/MC3359/MC3361 B FM IFs. In this case the op amp
would serve as an active noise filter, the output of which
would be rectified and compared to a reference on a squelch
gate. The MC3363 does not have a dedicated squelch gate,
but the NPN RF input stage or data shaping comparator
might be used to provide this function if available. The op
amp is a basic type with the inverting input and the output
available. This application frees the meter drive to allow it to
be used as a linear signal strength monitor.
The circuit of Figure 4 is a complete 50 MHz receiver from
antenna input to audio preamp output. It uses few
components and has good performance. The receiver
operates on a single channel and has input sensitivity of
< 0.31lV for 12 dB SINAD.

FM IF

The MC3371 and MC3372 perform single conversion FM reception and
consist of an oscillator, mixer, limiting IF amplifier, quadrature discriminator,
active filter, squelch switch, and meter drive circuitry. These devices are
designed for use in FM dual conversion communication equipment. The
MC3371/MC3372 are similar to the MC3361/MC3357 FM IFs, except that a
signal strength indicator replaces the scan function controlling driver which is
in the MC3361/MC3357. The MC3371 is designed for the use of parallel LC
components, while the MC3372 is designed for use with either a 455 kHz
ceramic discriminator, or parallel LC components.
These devices also require fewer external parts than earlier products. The
MC3371 and MC3372 are available in dual-in-line and surface mount
packaging.

MOTOROLA ANALOG IC DEVICE DATA

MC3371 MC3372
CIRCUIT DESCRIPTION
The MC3371 and MC3372 are low power narrowband FM
receivers with an operating frequency of up to 60 MHz. Its low
voltage design provides low power drain, excellent
sensitivity, and good image rejection in narrowband voice
and data link applications.
This part combines a mixer, an IF (intermediate frequency)
limiter with a logarithmic response signal strength indicator, a
quadrature detector, an active filter and a squelch trigger
circuit. In a typical application, the mixer amplifier converts an
RF input signal to a 455 kHz IF signal. Passing through an
external bandpass filter, the IF signal is fed into a limiting
amplifier and detection circuit where the audio signal is
recovered. A conventional quadrature detector is used.
The absence of an input signal is indicated by the
presence of noise above the desired audio frequencies. This
"noise band" is monitored by an active filter and a detector. A
squelch switch is used to mute the audio when noise or a
tone is present. The input signal level is monitored by a meter
drive circuit which detects the amount of IF signal in the
limiting amplifier.

APPLICATIONS INFORMATION
The oscillator is an internally biased Colpitts type with the
collector, base, and emitter connections at Pins 4, 1 and 2
respectively. This oscillator can be run under crystal control.
For fundamental mode crystals use crystal characterized
parallel resonant for 32 pF load. For higher frequencies, use
3rd overtone series mode type crystals. The coil (l2) and
resistor RD (R13) are needed to ensure proper and stable
operation at the LO frequency (see Figure 13, 45 MHz
application circuit).
The mixer is doubly balanced to reduce spurious radiation.
Conversion gain stated in the AC Electrical Characteristics
table is typically 20 dB. This power gain measurement was
made under stable conditions using 'a 50 0 source at the
input and an external load provided by a 455 kHz ceramic
filter at the mixer output which is connected to the VCC (Pin 4)
and IF input (Pin 5). The filter impedance closely matches the
1.8 kQ internal load resistance at Pin 3 (mixer output). Since
the input impedance at Pin 16 is strongly influenced by a
3.3 kO internal biasing resistor and has a low capaCitance,
the useful gain is actually much higher than shown by the
standard power gain measurement. The Smith Chart plot in
Figure 17 shows the measured mixer input impedance
versus input frequency with the mixer input matched to a
50 0 source impedance at the given frequencies. In order to
assure stable operation under matched conditions, it is
necessary to provide a shunt resistor to ground. Figures 11,
12 and 13 show the input networks used to derive the mixer
input impedance data.
Following the mixer, a ceramic bandpass filter is
recommended for IF filtering (I.e. 455 kHz types having a
bandwidth of ±2.0 kHz to ±15 kHz with an input and output
impedance from 1.5 kO to 2.0 kQ). The 6 stage limiting IF

MOTOROLA ANALOG IC DEVICE DATA

amplifier has approximately 92 dB of gain. The MC3371 and
MC3372 are different in the limiter and quadrature detector
circuits. The MC3371 has a 1.8 kQ and a 51 kQ resistor
providing internal dc biasing and the output of the limiter is
internally connected, both directly and through a 10 pF
capacitor to the quadrature detector; whereas, in the
MC3372 these components are not provided internally. Thus,
in the MC3371, no external components are necessary to
match the 455 kHz ceramic filter, while in the MC3372,
external 1.8 kQ and 51 kO biasing resistors are needed
between Pins 5 and 7, respectively (see Figures 12 and 13).
In the MC3371, a parallel LCR quadrature tank circuit is
connected externally from Pin 8 to VCC (similar to the
MC3361). In the MC3372, a quadrature capaCitor is needed
externally from Pin 7 to Pin 8 and a parallel LC or a ceramic
discriminator with a damping resistor is also needed from
Pin 8 to VCC (similar to the MC3357). The above external
quadrature circuitry provides 90° phase shift at the IF center
frequency and enables recovered audio.
The damping resistor determines the peak separation of
the detector and is somewhat critical. As the resistor is
decreased, the separation and the bandwidth is increased
but the recovered audio is decreased. Receiver sensitivity is
dependent on the value of this resistor and the bandwidth of
the 455 kHz ceramic filter.
On the chip the composite recovered audio, consisting of
carrier component and modulating Signal, is passed through
a low pass filter amplifier to reduce the carrier component
and then is fed to Pin 9 which has an output impedance of
450 O. The signal still requires further filtering to eliminate
the carrier component, deemphasis, volume control, and
further amplification before driving a loudspeaker. The
relative level of the composite recovered audio signal at Pin 9
should be considered for proper interaction with an audio
post amplifier and a given load element. The MC13060 is
recommended as a low power audio amplifier.
The meter output indicates the strength of the IF level and
the output current is proportional to the logarithm of the IF
input signal amplitude. A maximum source current of 60 jlA is
available and can be used to drive a meter and to detect a
carrier presence. This is referred to as a Received Strength
Signal Indicator (RSSI). The output at Pin 13 provides a
current source. Thus, a resistor to ground yields a voltage
proportional to the input carrier signal level. The value of this
resistor is estimated by (VCC(Vdc) - 1.0 V)/60 jlA; so for
VCC = 4.0 Vdc, the resistor is approximately 50 kQ and
provides a maximum voltage swing of about 3.0 V.
A simple inverting op amp has an output at Pin 11 and the
inverting input at Pin 10. The noninverting input is connected
to 2.5 V. The op amp may be used as a noise triggered
squelch or as an active noise filter. The bandpass filter is
designed with external impedance elements to discriminate
between frequencies. With an external AM detector, the
filtered audio signal is checked for a tone signal or for the
presence of noise above the normal audio band. This
information is applied to Pin 12.

MC3371 MC3372
An external positive bias to Pin 12 sets up the squelch
trigger circuit such that the audio mute (Pin 14) is open or
connected to ground. If Pin 12 is pulled down to 0.9 V or
below by the noise or tone detector, Pin 14 is internally
shorted to ground. There is about 57 mV of hyteresis at
Pin 12 to prevent jitter. Audio muting is accomplished by
connecting Pin 14 to the appropriate point in the audio path
between Pin 9 and an audio amplifier. The voltage at Pin 14
should not be lower than -D.7 V; this can be assured by
connecting Pin 14 to the pOint that has no dc component.

Another possible application of the squelch switch may
be as a carrier level triggered squelch circuit, similar to the
MC3362/MC3363 FM receivers . .In this case the meter
output can be used directly to trigger the squelch switch
when the RF input at the input frequency falls below the
desired level. The level at which this occurs. is determined
by the resistor placed between the meter drive output
(Pin 13) and ground (Pin 15).

MOTOROLA ANALOG IC DEVICE DATA

MC3374
CIRCUIT DESCRIPTION
The MC3374 is an FM narrowband receiver capable of
operation to 75 MHz. The low voltage design yields low
power drain and excellent sensitivity in narrowband voice
and data link applications. In the typical application the mixer
amplifies the incoming RF or IF signal and converts this
frequency to 455 kHz. The signal is then filtered by a 455 kHz
ceramic filter and applied to the first intermediate frequency
(IF) amplifier input, before passing through a second ceramic
filter. The modulated IF signal is then applied to the limiting IF
amplifi,er and detector circuitry. Modulation is recovered by a
conventional quadrature detector. The typical modulation
bandwidth available is 3.0 to 5.0 kHz.
Features available include buffers for audio/data
amplification and active filtering, on board voltage regulator,
low battery detection circuitry with programmable level, and
receiver disable circuitry. The MC3374 is an FM utility
receiver to be used for voice and/or narrowband data
reception. It is especially suitable where extremely low power
consumption and high design flexibility are required.

APPLICATION
The MC3374 can be used as a high performance FM IF for
the use in low power dual conversion receivers. Because of
the MC3374's extremely good sensitivity (0.6 IlV for 20 dB
(S+N/N, see Figure 3)), it can also be used as a stand alone
single conversion narrowband receiver to 75 MHz for
applications not sensitive to image frequency interference.
An RF preamplifier will likely be needed to overcome
preselector losses.
The oscillator is a Colpitts type which must be run under
crystal control. For fundamental mode crystals choose
resonators, parallel resonant, for a 32 pF load. For higher
frequencies, use a 3rd overtone series mode type. The coil
l2 and RD resistor are needed to ensure proper operation.
The best adjacent channel and sensitivity response occur
when two 455 kHz ceramic filters are used, as shown in
Figure 1. Either can be replaced by a 0.1 IlF coupling
capacitor to reduce cost, but some degradation in sensitivity
and/or stabil'ity is suspected.
The detector is a quadrature type, with the connection
from the limiter output to the detector input provided
internally. A 455 kHz LC tank circuit must be provided
externally. One of the tank pins (Pin 8) must be decoupled
using a 0.1 IlF capacitor. The 56 kg damping resistor (see
Figure 1), determines the peak separation of the detector
(and thus its bandwidth). Smaller values will increase the
separation and bandwidth but decrease recovered audio and
sensitivity.
The data buffer is a noninverting amplifier with a nominal
voltage gain of 2.7 VN. This buffer needs its dc bias
(approximately 250 mV) provided externally or else
debiasing will occur. A 2nd order Sail en-Key low pass filter,
as shown in Figure 1, connecting the recovered audio output
to the data buffer input provides the necessary dc bias and
some post detection filtering: The buffer can also be used as
an active filter.

MOTOROLA ANALOG IC DEVICE DATA

The audio buffer is a non inverting amplifier with a nominal
voltage gain of 4.0 VN. This buffer is self-biasing so its input
should be ac coupled. The two buffers, when applied as
active filters, can be used together to allow simultaneous
audio and very low speed data reception. Another possible
configuration is to receive audio only and include a
noise-triggered squelch.
The comparator is a noninverting type with an open
collector output. Typically, the pull-up resistor used between
Pin 14 and VCC is 100 kU With RL =100 kg the comparator
is capable of operation up to 25 kHz. The circuit is
self-biasing, so its input should be ac coupled.
The regulator is a 1.07 V reference capable of sourcing
3.0 mAo This pin (Pin 17) needs to be decoupled using a
1.0-10 IlF capacitor to maintain stability of the MC3374.
All three VCCs on the MC3374 (VCC, VCC2, VCC3) run on
the same supply voltage. VCC is typically decoupled using
capacitors only. VCC2 and VCC3 should be bypassed using
the RC bypasses shown in Figure 1. Eliminating the resistors
on the VCC2 and VCC3 bypasses may be possible in some
applications, but a reduction in sensitivity and quieting will
likely occur.
The low battery detection circuit gives an NPN open
collector output at Pin 20 which drops low when the MC3374
supply voltage drops below 1.2 V. Typically it would be pulled
up via a 100 kn resistor to supply.
The 1.2 V Select pin, when connected to the MC3374 supply,
programs the low battery detector to trip at VCC < 1.1 V. Leaving
this pin open raises the trip voltage on the low battery detector.
Pin 15 is a receiver enable which is connected to VCC for
normal operation. Connecting this pin to ground shuts off
receiver and reduces current drain to ICC < 0.5 /lA.

MC13055
GENERAL DESCRIPTION
The MC13055 is an extended frequency range FM IF,
quadrature detector, signal strength detector and data
shapero It is intended primarily for FSK data systems. The
design is very similar to MC3356 except that the
oscillator/mixer has been removed, and the frequency
capability of the IF has been raised about 2:1. The detector
output configuration has been changed to a balanced,
open--collector type to permit symmetrical drive of the data
shaper (comparator). Meter drive and squelch features have
been retained.
The limiting IF is a high frequency type, capable of being
operated up to 100 MHz. It is expected to be used at 40 MHz
in most cases. The quadrature detector is internally coupled
to the IF, and a 2.0 pF quadrature capacitor is internally
provided. The 20 dB quieting sensitivity is approximately
20 IlV, tuned input, and the IF can accept signals up to
220 mVrms without distortion or change of detector
quiescent DC level.
The IF is unusual in that each of the last 5 stages of the
6 stage limiter contains a signal strength sensitive, current
sinking device. These are parallel connected and buffered

to produce a signal strength meter drive which is fairly linear
for IF input signals of 20 IlV to 20 mVrms (see Figure 4).
A simple squelch arrangement is provided whereby the
meter current flowing through the meter load resistance flips
a comparator at about 0.8 Vdc above ground. The signal
strength at which this occurs can be adjusted by changing
the meter load resistor. The comparator (+) input and output
are available to permit control of hysteresis. Good positive
action can be obtained for IF input signals of above
20 IlVrms. A resistor (R) from Pin 13 to Pin 12 will provide
VCclR of feedback current. This current can be correlated to
an amount of signal strength hysteresis by using Figure 4.
The squelch is internally connected to the data shapero
Squelch causes the data shaper to produce a high (VCC)
output.
The data shaper is a complete "floating" comparator, with
diodes across its inputs. The outputs of the quadrature
detector can be fed directly to either or preferably both inputs
of the comparator to produce a squared output swinging from
VCC to ground in inverted or noninverted form.

PLL I/O Pin Specifications
The 2nd LO, Rx and Tx PLL's and MPU serial interface are
normally powered by the internal voltage regulator at the
"PLL Vref' pin. The "PLL Vref' pin is the output of a voltage
regulator which is powered from the "Vee Audio" power
supply pin. Therefore, the maximum input and output levels
for most PLL 1/0 pins (L02 In, L02 Out, Rx PD, Tx PD, Tx
VeO) is the regulated voltage at the "PLL Vret" pin. The ESD
protection diodes on these pins are also connected to "PLL
Vref'. Internal level shift buffers are provided for the pins
(Data, elk, EN, elk Out) which connect directly to the
microprocessor. The maximum input and output levels for
these pins is Vee. Figure 9 shows a simplified schematic of
the PLL 1/0 pins.

Microprocessor Serial Interface
The "Data", "elk", and "EN" pins provide an MPU serial
interface for programming the reference counters, the
transmit and receive channel divider counter and various
control functions. The "Data" and "elk" pins are used to load
data into the shift register. Figure 10 shows "Data" and "elk"
pin timing. Data is clocked on positive clock transitions.

Data,
Clk, EN

Data

Clk------'

\"----

After data is loaded into the shift register, the data is
latched into the appropriate latch register using the "EN" pin.
This is done in two steps. First, an 8-bit address is loaded
into the shift register and latched into the 8-bit address latch
register. Then, up to 18-bits of data is loaded into the shift
register and latched into the data latch register specified by
the address that was previously loaded. Figure 11 shows the
timing required on the EN pin. Latching occurs on the
negative EN transition.
Figure 11. Enable Timing Requirement

EN _ _ _. J

Previous Data Latched

8-143

MC13109
The state of the EN pin when clocking data into the shift
register determines whether the data is latched into the
address register or a data register. Figure 12 shows the
address and data programming diagrams. In the data
programming mode, there must not be any clock transitions
when "EN" is high. The clock can be in a high state (default
high) or a low state (default low) but must not have any
transitions during the "EN" high state. The convention in
these figures is that latch bits to the left are loaded into the
shift register first.

Status Out
This is a digital output which indicates whether the latch
registers have, been reset to their power-up default values.
Latch power-up default values are given in Figure 32. If there
is a power glitch or ESD event which causes the latch
registers to be reset to their default values, the "Status our
pin will indicate this to the MPU so it can reload the correct
information into the latch registers.

~

The MPU serial interface is fully operational within 100 j.1s
after the power supply has reached its minimum level during
power-up (See Figure 13). The MPU Interface shift registers
and data latches are operational in all four power saving
modes; Inactive, Standby, Rx , and Active Modes. Data can
be loaded into the shift registers and latched into the latch
registers in any of the operating modes.

Reference Counter
Figure 17 shows how the reference frequencies for the Rx
and Tx loops are generated. All countries except U.K. require
that the Tx and Rx reference frequencies be identical. In this
case, set "U.K. Base Selecf' and "U.K. Handset Selecf' bits
to "0". Then the fixed divider is set to "1" and the Tx and Rx
reference frequencies will be equal to the crystal oscillator
frequency divided by the programmable reference counter
value. The U.K. is a special case which requires a different
reference frequency value fo T x and Rx.
For U.K. base operation, set "U.K. Base Select" to "1". For
U.K. handset operation, set "UK Handset Selecf' to "1". The
Netherlands is also a special case since a 2.5 kHz reference
frequency is used for both the Tx and Rx reference and the
total divider value required is 4096 which is larger than the
maximum divide value available from the 12-bit reference
divider (4095). In this case, set "U.K. Base Select" to "1" and
set "U.K. Handset Select" to "1". This will give a fixed divide
by 4 for both the Tx and Rx reference. Then set the reference.
divider to 1024 to get a total divider of 4096.
Mode Control Register
Power saving modes, mutes, disables, volume control,
and microprocessor clock output frequency are all set by the
Control Register. Operation of the Control Register is
explained in Figures 18 through 25.

Power Saving Operating Modes
When the MC13109 is used in a handset, it is important to
conserve power in order to prolong battery life. There are five
modes of operation; Active, Rx , Standby, Interrupt and
Inactive. In Active Mode, all circuit blocks are powered. In Rx
mode, all circuitry is powered down exept for those circuit

8-146

sections needed to receive a transmission from the base. In
the Standby and Interrupt Modes, all circuitry is powered
down except for the circuitry needed to provide the clock
output for the microprocessor. In Inactive Mode, all circuitry is
powered down except the MPU interface. Latch memory is
maintained in all modes. Figure 20 shows the control register
bit values for selection of each power saving mode and
Figure 21 show the circuit blocks which are powered in each
of these operating mode.

Inactive Mode Operation and Hardware Interrupt
In some handset applications it may be desirable to power
down all circuitry including the microprocessor (MPU). First
put the MC13109 into the Inactive mode, which turns off the
MPU Clock Output (see Figure 22), and then disable the
microprocessor. In order to give the MPU adequate time to
power down, the MPU Clock output remains active for a
minimum of one reference counter cycle (about 200 ~s) after
the command is given to switch into the "Inactive" mode. An
external timing circuit should be used to initiate the turn-on
sequence. The "CD Out" pin has a dual function. In the Active
and Rx modes it performs the carrier detect function. In the

Standby and Inactive modes the carrier detect circuit is
disabled and the "CD Ouf' pin is in a "High" state due to the
external pull-up resistor. In the Inactive mode the "CD Out"
pin is the input for the hardware interrupt function. When the
"CD Out" pin is pulled "low" by the external timing circuit, the
MC13109 swtiches from the Inactive to the Interrupt mode
thereby turning on the MPU Clock Output. The MPU can then
resume control of the combo IC. The "CD Out" pin must
remain low until the MPU changes the operating mode from
Interrupt to Standby, Active or Rx modes.

harmonics. In order to minimize radiated noise, a 1.0 kn
resistor is included on-chlp In-series with the "Clk Out" output
driver. A small capaCitor can be connected to the "Clk Ouf' line
on the PCB to form a single pole low pass filter. This filter will
significantly reduce noise radiated from the "Clk Out" line.
Volume Control
The volume control can be programmed in 2.0 dB gain
steps from -14 dB to +16 dB. The power-up default value is
OdB.

MPU "Clk Out" Pow.......Up Default Dlvld.r Value
The power-up default divider value Is "divide by 10". This
provld.s an MPU clock of about 1.0 MHz after initial
power-up. The reason for choosing this relatively low clock
frequency after Intlal power-up is that some microprocessors
that operate down to a 2.0 V power supply have a maximum
clock frequency fo 1.0 MHz. After initial power-up, the MPU
can change the clock divider value to set the clock to the
desired operating frequency. Special care has been taken in
the design of the clock divider to ensure that the transition
between one clock divider value and another Is "smooth"
(I.e., there will be no narrow clock pulses to disturb the MPU).

Th "CD Out" pin will give an indication to the
microprocessor if a carier signal is present on the selected
channel. The nominal value and tolerance of the carrier
detect threshold is given in the carrier detect specification

section of this document. If a different carrier detect threshold
value is desired, it can be set through the MPU interface as
shown in Figure 27 below.

latch control bit values.
The Internal varactor temperature coefficient Is 1800 ppm/°C
(CO =8.9 pF at 25°C, Vcap control voltage =1.2 V, Freq =
36 MHz). Customer Is sugg,ested to use a negative
temperature coefficient capacitor In 1st LO tank circuit when
the whole operating temperature range of -40 to +85°C Is
considered.

Auxiliary Reglater

The auxiliary register contains a 3-bit 1st LO Capacitor

There Is a very large frequency difference between the
minimum and maximum channel frequencies in the proposed
25 Channel U.S. standard. The sensitivity of the 1st LO is not
large enough to accommodate this large frequency variation.
Fixed capacitors can be connected across the 1st LO tank
circuit to change the 1st LO sensitivity. Internal switches and
capacitors are provided to enable microprocessor control
over Internal fixed capaCitor values. Figure 29 shows the

NOTE: To determine the correct output, look at the lower 8 bits in the Rx or Tx register (Divisor (7;0). If the value 01 the divisor is > 16, then the output divisor
value is Divisor (7;2) (the upper 6 bits 01 the divisor). II Divisor (7;0) < 16 and Divisor (3;2) > = 2, then output divisor value Is Divisor (3;2) (btts 2 and 3
01 the divisor). II Divisor (7;0) < 16 and Divisor (3;2) < 2, then output divisor value is (Divisor (3;2) + 60).

Test Modes
Test Mode Control latch bits enable independent testing
of internal counters and set AGC Gain Options. In test
mode, the "Tx VCO" input pin is multiplexed to the input of
the counter under test and the output of the counter under
test is multiplexed to the "Clk Out" output pin so that each
counter can be individually tested. Make sure test mode bits
are set to "0" for normal operation. Test mode operation is
described in Figure 31. During normal operation and when
testing the Tx Prescaler, the "Tx VCO" input can be a
minimum of 200 mVpp at 80 MHz and should be ac coupled.
For other test modes, input signals should be standard logic
levels of 0 to 2.2 V and a maximum frequency of 16 MHz.

Power-Up Defaults for Control and Counter Registers
When the IC is first powered up, all latch registers are
initialized to a defined state. The MC13109 is initially placed in
the Rx mode with all mutes active and nothing disabled. The
reference counter is set to generate a 5.0 kHz reference
frequency from a 10.24 MHz crystal. The MPU clock output
divider is set to 10 to give the minimum clock output frequency.
The Tx and Rx latch registers are set for USA Channel
Frequency #21. Figure 32 shows the initial power-up states
for all latch registers.

FM Receiver
The FM receiver can be used with either a quad coil or a
ceramic resonator. The FM receiver and 1st LO have been
designed to work for all country channels, including 25
channel U.S., without the need for any external switching
circuitry (see Figure 29).
.
RSSI/Carrler Detect
Connect 0.01 ~F to Gnd from "RSSI" output pin to form the
carrier detect filter. "CD Out" is an open collector output
which requires an external 100 kQ pull-up resistor to VCC.
The carrier detect threshold is programmable through the
MPU interface.
Data Amp Comparator
The data amp comparator is an inverting hysteresis
comparator. Its open collector output has an Internal 100 kO
pull-up resistor. A band pass filter is connected between the
"Det Out" pin and the "DA In" pin with component values as
shown in Figure 1 (Test Circuit). The "DA In" Input signal is
ac-coupled.

The Rx Audio signal path goes from "Rx Audio In" (Pin 24)
to "E Out" (Pin 46). The "Rx Audio In" input signal is ac
coupled. AC couple between "Scr Out" and "E In" (see
Figure 3).
Speaker AmplSP Mute
The Speaker Amp is an inverting rail-to-rail operational
amplifier. The noninvertlng input Is connected to the internal VB
reference. Extemal resistors and capacitors are used to set the
gain and frequency response. The "SA In" Input is ac coupled.

MlcAmp
The Mic Amp is an inverting rail-te-rail operational amplifier
with noninverting input terminal connected to internal VB
reference. External resistors and capacitors are set to the gain
and frequency response. The ''Tx In" input is ac coupled.
Tx Audio Path (Compressor/ALCITx Mute!
Llmlter/LPFITx Gain Adjust)
The Tx Audio signal path goes from "c In" (Pin 19) to "Tx
Out" (Pin 17). The "c In" input signal is ac coupled. The ALC
(Automatic Level Control) provides a "soft" limit to the output
signal swing as the input voltage increases slowly (i.e., a sine
wave is maintained). The Limiter circuit limits rapidly
changing signal levels by clipping the signal peaks. The ALC
and/or Limiter can be disabled through the MPU serial
interface (see Figure 4).
T x and Rx Scrambler
The Tx and Rx signal paths each contain a frequency
inversion scrambler in the MC13110. Each scrambler
contains a pre-mixer low pass switched capacitor filter
(SCF), a double balanced mixer and a post-mixer low pass
switched capacitor filter. The scrambler function can be
defeated by setting the Tx or Rx Scrambler Bypass bits in the
control register to "1" through the MPU interface. In this
mode, the mixer and the post-mixer LPF are bypassed and

MOTOROLA ANALOG IC DEVICE DATA

MC13110
only the pre-mixer LPF remains in the signal path. The SCF
corner frequencies are proportional to the SCF clock. The
SCF Clock Divider is programmable through the MPU
interface, (SCF Clock) = F(2nd LO)/(SCF Divider Value*2).
The scrambler modulation frequency is (SCF Clock)/40. Four
scrambler modulation frequencies may be selected (see
Figures 28 and 29).
PLL Voltage Regulator
The "PLL Vre(' pin is the internal supply voltage for the Ax
and Tx PLL's. It is regulated to a nominal 2.5 V. The "VCC
Audio" pin is the supply voltage for the internal voltage
regulator. Two capacitors with 10 IiF and 0.1 IiF values must
be connected to the "PLL Vre( pin to filter and stabilize this
regulated voltage. The "PLL Vret" pin may be used to power
other IC's as long as the total external load current does not
exceed 1.0 mAo The tolerance of the regulated voltage is
initially ±8.0%, but is improved to ±4.0% after the internal
Bandgap voltage reference is adjusted electronically through
the MPU serial interface. The voltage regulator is turned off in
the Standby and Inactive modes to reduce current drain. In
these modes, the "PLL Vre( pin is internally connected to the
"V CC Audio" pin (i.e., the power supply voltage is maintained
but is now unregulated).
Low Battery Detect
Two external precision resistor dividers are used to set
independent thresholds for two battery detect hysteresis
comparators. The voltages on "Aef1" and "Aef2" are
compared to an internally generated 1.5 V reference voltage.
The tolerance of the internal reference voltage is initially
±6.0%. The Low Battery Detect threshold tolerance can be
improved by adjusting a trim-pot in the external resistor
divider. Alternately, the tolerance of the internal reference
voltage can be improved to ±1.5% through MPU serial
interface programming. The internal reference can be
measured directly at the "VB" pin. During final test of the
telephone, the VB internal reference voltage is measured.
Then, the internal reference voltage value is adjusted
electronically through the MPU serial interface to achieve the
desired accuracy level. The voltage reference register value
should be stored in AOM during final test so that it can be
reloaded each time the MC13110 IC is powered up. Low
Battery Detect outputs are open collector.

Power Supply Voltage
This circuit is used in a cordless telephone handset and
base unit. The handset is battery powered and can operate
on three NiCad cells or on 5.0 V supply.
PLL Frequency Synthesizer General Description
Figure 5 shows a simplified block diagram of the
programmable universal dual phase locked loop (PLL). This
dual PLL is fully programmable through the MCU serial
interface and supports most country channel frequencies
including USA (25 ch), Spain, Australia, Korea, New
Zealand, U. K., Netherlands, France, and China.
The 2nd local oscillator and reference divider provide the
reference frequency for the receive (Ax) and transmit (Tx)
PLL loops. The programmed divider value for the reference
divider is selected based on the crystal frequency and the
desired Ax and Tx reference frequency values. Additional
divide by 25 and divide by 4 blocks are provided to allow for
generation of the 1.0 kHz and 6.25 kHz reference
frequencies required for the U. K. The 14-bit Tx counter is
programmed for the desired transmit channel frequency. The
14-bit Ax counter is programmed for the desired first local
oscillator frequency. All counters power up in the proper
default state for USA channel #21 (channel #6 for FCC 10
channel band) and for a 10.24 MHz reference frequency
crystal. Internal fixed capacitors can be connected to the tank
circuit of the 1st LO through microprocessor control to extend
the sensitivity of the 1st LO for U.S. 25 channel operation.
PLL I/O Pin Specifications
The 2nd LO, Ax and Tx PLL's, and MPU serial interface are
powered by the internal voltage regulator at the "PLL Vre('
pin. The "PLL Vret" pin is the output of a voltage regulator
which is powered from the "VCC Audio" power supply pin and
is regulated by an internal bandgap voltage reference.
Therefore, the maximum input and output levels for most PLL
I/O pins (L02 In, L02 Out, Ax PD, Tx PD, Tx VCO) is the
regulated voltage at the "PLL Vret" pin. The ESD protection
diodes on these pins are also connected to "PLL Vret".
Internal level shift buffers are provided for the pins (Data, Clk,
EN, Clk Out) which connect directly to the microprocessor.
The maximum input and output levels for these pins is VCC.
Figure 6 shows a simplified schematic of the I/O pins.

Data, Clk and EN Pins

The state of the EN pin when clocking data into the shift
register determines whether the data is latched into the
address register or a data register. Figure '9 shows the
address and data programming diagrams. In the data
programming mode, there must not be any clock transitions
when "EN" is high. The clock can be in a high state (default
high) or a low state (default low) but must not have any
transitions during the "EN" high state. The convention in
these figures is that latch bits to the left are loaded into the
~hift register first.

Microprocessor Serial Interface
The "Data", "elk", and "EN" pins provide an MPU serial
interface for programming the reference counters, the
transmit and receive channel divider counters, the switched
capacitor filter clock counter, and various control functions.
The "Data" and "elk" pins are used to load data into the shift
register. Figure 7 shows the timing required on the "Data" and

Data Register Programming Mode

The MPU serial interface is·fully operational within 100 j.IS
after the power supply has reached its minimum level during
power-up (see Figure 10). The MPU Interface shift registers
and data latches are operational in all four power saving
modes; Inactive, Standby, Rx , and Active Modes. Data can
be loaded into the shift registers and latched into the latch
registers in any of the operating modes.

Data

Clk

After data is loaded into the shift register, the data is
latched into the appropriate latch register using the "EN" pin.
This is done in two steps. First, an 8-bit address is loaded
into the shift register and latched into the 8-bit address latch
register. Then, up to 16-bits of data is loaded into the shift
register and latched into the data latch register specified by
the address that was previously loaded. Figure 5 shows the
timing required on the EN pin. Latching occurs on the
negative EN transition.

Reference Frequency Selection
The "L02In" and "L02 Ouf' pins form a reference oscillator
when connected to an external parallel-resonant crystal. The
reference oscillator is also the second local oscillator for the
RF Receiver. Figure 12 shows the relationship between
different crystal frequencies and reference frequencies for
cordless phone applications in various countries. "L02 In"
may also serve as an input for an externally generated
reference signal which is ac-coupled. The switched
capacitor filter 6-bit programmable counter must be
programmed for the crystal frequency that is selected since
MOTOROLA ANALOG IC DEVICE DATA

this clock is derived from the crystal frequency and must be
held constant regardless of the crystal that is selected. The
actual switched capacitor clock divider ratio is twice the
programmed divider ratio since there is a fixed divide by 2.0
after the programmable counter. The scrambler mixer
modulation frequency is the switched capacitor clock divided
by 40.

In this case, set "U.K. Base Select" and "U.K. Handset

Tx and Rx reference frequencies will be equal to the crystal
oscillator frequency divided by the programmable reference
counter value. The U.K. is' a special case which requires a
different reference frequency value for Tx and Rx. For U.K.
base operation, set "U.K. Base Selecr to "1". For U.K.
handset operation, set "U.K. Handset Selecr to "1".The
Netherlands is also a special case since a 2.5 kHz reference
frequency is used for both the Tx and Rx reference and the

Power Saving Operating Modes
When the MC1311 0 is used in a handset, it is important to
conserve power in order to prolong battery life. There are five
modes of operation; Active, Rx , Standby, Interrupt, and
Inactive. In Active mode, all circuit blocks are powered. In Rx
mode, all circuitry is powered down except for those circuit
sections needed to receive a transmission from the base. In
the Standby and Interrupt Modes, all circuitry is powered
down except for the Circuitry needed to provide the clock
output for the microprocessor. In Inactive Mode, all circuitry is
powered down except the MPU interface. Latch memory is
maintained in all modes. Figure 16 shows the control register
bit values for selection of each power saving mode and
Figure 17 shows the circuit blocks which are powered in each
of these operating modes.

MOTOROLA ANALOG IC DEVICE DATA

NOTE: In Standby and Inactive Modes, "PLL Vrer remains powered but
is not regulated. It will fluctuate with Vee.

Inactive Mode Operation and Hardware Interrupt
In some handset applications it may be desirable to power
down all circuitry including the microprocessor (MPU). First
put the combo IC into the Inactive mode, which turns off the
MPU Clock Output (see Figure 18), and then disable the
microprocessor. In order to give the MPU adequate time to
power down, the MPU Clock output remains active for a
minimum of one reference counter cycle (about 200 /lS) after
the command is given to switch into the "Inactive" mode. An
external timing circuit should be used to initiate the turn-on
sequence. The "CD Ouf' pin has a dual function. In the Active
and Rx modes it performs the carrier detect function. In the
Standby and Inactive modes the carrier detect circuit is
disabled and the "CD Ouf' pin is in a "High" state due to the
external pull-up resistor. In the Inactive mode, the "CD Ouf'
pin is the input for the hardware interrupt function. When the
"CD Ouf' pin is pulled "low" by the external timing circuit, the
combo IC switches from the Inactive to the Interrupt mode
thereby turning on the MPU Clock Output. The MPU can then
resume control of the combo IC. The "CD Out" pin must
remain low until the MPU changes the operating mode from
Interrupt to Standby, Active or Rx modes.

cause problems in the system especially if the clock is a
square wave digital signal with large high frequency
harmonics. In order to minimize radiated noise, a 1.0 kQ
resistor is included on-chip in series with the "Clk Out" output
driver. A small capacitor can be connected to the "Clk Out"
line on the PCB to form a single pole low pass filter. This filter
will significantly reduce noise radiated from the "Clk Out" line.

The volume control adjustable gain block can be
programmed in 2.0 dB gain steps from -14 dB to +16 dB. The

Gain Control Register
The gain control register contains bits which control the Tx
Voltage Gain, Rx Voltage Gain, and Carrier Detect threshold.
Operation of these latch bits are explained in Figures 22, 23
and 24.

Tx and Rx Gain Programming
The T x and Rx audio signal paths each have a
programmable gain block. If a Tx or Rx voltage gain other
than the nominal power-up default is desired, it can be
programmed through the MPU interface. Alternately, these
programmable gain blocks can be used during final test of the
telephone to electronically adjust for gain tolerances in the
telephone system as shown in Figure 23. In this case, the T x
and Rx gain register values should be stored in ROM during
final test so that they can be reloaded each time the combo
IC is powered up.

Carrier Detect Threshold Programming
The "CD Ouf' pin gives an indication to the microprocessor
if a carrier signal is present on the selected channel. The
nominal value and tolerance of the carrier detect threshold is
given in the carrier detect specification section of this
document. If a, different carrier detect threshold value is
desired, it can be programmed through the MPU interface as
shown in Figure 24. Alternately, the carrier detect threshold

can be electronically adjusted during final, test of the
telephone to reduce the tolerance of the carrier detect
threshold., This is done by measuring the threshold and then
by adjusting the threshold through the MPU interface. In this
case, it is necessary to store the carrier detect register value
in ROM so that the CD register can be reloaded each time the
combo IC is powered up.

explained in Figures 25 through 30.

The SCF divider should be set to a value which gives a
SCF Clock as close to 165.16 kHz as possible based on the
2nd LO frequency which is chosen (see Figure 12).

Switched Capacitor Filter Clock Programming
A block diagram of the switched capacitor filter and
scrambler modulation clock dividers is shown in Figure 27.
There is a fixed divide by 2 after the programmable divider.
The switched capacitor filter clock value is given by the
following equation;
(SCF Clock) = F(2nd LO)/(SCF Divider Value * 2)
The scrambler modulation clock frequency (SMCF) is
proportional to the SCF clock and is given by the following
equation;

Scrambler Modulation Frequency Programming
Four different scrambler modulation frequencies may be
selected by programming the SCF Clock divider as shown in
Figures 28 and 29. Note that all filter corner frequencies will
change proportionately with the SCF Clock and Scrambler
Modulation Frequency. The power-up default SCF Clock
divider value is 31.

Voltage Reference Adjustment
The internal 1.5 V Bandgap voltage reference provides the
voltage reference for the "B01 Out" and "B02 Ouf' low
battery detect circuits, the "PLL Vret" voltage regulator, the
"VB" reference, and all internal analog ground references.
The initial tolerance of the Bandgap voltage reference is
±6%. The tolerance of the internal reference voltage can be
improved to ±1.5% through MPU serial interface
programming.
During final test of the telephone, the battery detect
threshold is measured. Then, the internal reference voltage
value is adjusted electronically through the MPU serial
interface to achieve the desired accuracy level. The voltage
reference register value should be stored in ROM during final
test so that it can be reloaded each time the MC13110 is
powered up (see Figure 30).

Test Modes
Digital and analog test modes can be selected through the
4-bit Test Mode Register. In digital test mode, the "Tx VCO"
input pin is multiplexed to the input of the counter under test
and the output of the counter under test is multiplexed to the
"Clk Out" output pin so that each counter can be individually
tested. Make sure test mode bits are set to "O's" for normal
operation. Digital test mode operation is described in
Figure 35. During normal operation and when testing the
T x Prescaler, the "Tx VCO" input can be a minimum of 200
mVpp at 80 MHz and should be ac-coupled. For other test
modes, input signals should be standard logic levels of 0 to
2.5 V and a maximum frequency of 16 MHz.
The analog test modes enable separate testing of the
Compressor and Tx Scrambler blocks as shown in Figure 36.

Also, ALC Gain options can be selected through analog test
modes.
Power-Up Defaults for Control and Counter Registers
When the IC is first powered up, all latch registers are
initialized to a defined state. The device is initially placed in the
Rx mode with all mutes active. The reference counter is set to
generate a 5.0 kHz reference frequency from a 10.24 MHz
crystal. The switched capacitor filter clock counter is set
properly for operation with a 10.24 MHz crystal. The scrambler
bypass mode control are set for normal operation of
scrambler. The Tx and Rx latch registers are set for USA
Channel Frequency 21 (Channel 6 for previous FCC 10
Channel Band). Figure 37 shows the initial power-up states
for all latch registers.

MOTOROLA ANALOG IC DEVICE DATA

MC13110
APPLICATIONS INFORMATION
Evaluation PC Board
The PCB should be double sided with a full ground plane
on one side; any leaded components are inserted on the
ground plane side. This affords shielding and isolation from
the circuit side of the PCB. The other side is the circuit side
which has the interconnect traces and the surface mount
components. In cases where cost allows, it may be benificial
to use multi layer boards.
The placement of certain components specified in the
application circuits is very critical. These components should
be placed first and the other less critical components are
fitted in last. In general, al/ RF paths should be kept as short
as possible, ground pins should be grounded at the pins and
VCC pins should have adequate decoupling to ground at the
pins. In mixed mode systems where digital and RF/Analog
circuitry are present, the VEE and VCC busses are isolated ac
-wise from each other.
Component Selection
The evaluation PC board is designed to accommodate
specific components, while in some cases it is versatile
enough to use components from various manufacturers and
coil types. The application circuit schematics specify
particular components that were used to achieve the results
shown in the typical curves and tables, but alternate
components should give similar results.
The MC13110 IC is capable of matching the sensitivity,
IMD, adjacent channel rejection, and other performance
criteria of a multi-chip analog cordless telephone system.
For the most part, the same external components are used
as in the multi-chip solution. In the following discussion,
various parts of the system are analyzed for best peformance
and cost tradeoffs. Specific recommendations are made
where certain components or circuit designs offer superior
performance. The system analyzed is the USA "CT-1"
cordless phone.
Input Matching/Sensitivity
The sensitivity of the IC is typically 0.5611Vrms matched
with no preamp. To achieve suitable system performance, a
preamp and passive duplexer must be used. In production
final test, each section of the IC is separately tested to
guarantee its system performance in the specific
application. The preamp and duplexer yields typically -114
dBm 12 dB SINAD sensitivity performance under full duplex
operation.
The duplexer is important to achieve full duplex operation
without significant "de-sensing" of the receiver by the
transmitter. The combination of the duplexer and preamp
circuit have to attenuate the transmitter power to the receiver
by over 60 dB to be effective. They do this while improving
the receiver system noise figure and without giving up too
much IMD intermodulation performance.
The duplexer may be a single piece unit offered by
Shimida and Sansui products (designed for 10 channel CT-1
cordless phone) or a two piece solution offered by Toko
(designed for 25 channel operation). The duplexer frequency
response at the receiver port has a notch at the transmitter

MOTOROLA ANALOG IC DEVICE DATA

frequency band of about 35 to 40 dB with a 2.0 to 3.0 dB
insertion loss at the receiver frequency band.
The preamp circuit utilizes a tuned transformer at the
output side of the amplifier; this transformer is designed to
bandpass filter the receiver input frequency while rejecting
the transmitter frequency. The tuned preamp also improves
the noise performance by reducing the bandwidth of the pass
band and reducing the second stage contribution of the 1st
mixer. The preamp is biased at about 1.0 mA and 3.0 Vdc
which yields suitable noise figure and gain.
Mixers
The 1st and 2nd mixers are similar in design. Both are
double balanced to suppress the LO and the input
frequencies to give only the sum and difference frequencies
out. Typically the LO is suppressed about 40 to 60 dB. The
1st mixer may be driven either differentially or single ended.
The gain of the 1st mixer has a 3.0 dB corner at 20 MHz and
is used at a 10.7 MHz IF. It has an output impedance of
330 n and matches to a typical 10.7 MHz ceramic filter with
a source and load impedance of 330 n. A series resistor may
be used to raise the impedance for use with crystal filters
which typically have an input impedance much greater than
330 n. The 2nd mixer input impedance is typically 3.0 kn; it
requires an external 360 n parallel resistor for use with a
standard 330 n 10.7 MHz ceramic filter. The second mixer
output impedance is 1.5 kn making it suitable to match
455 kHz ceramic filters.

over frequency for the 1st Mixer. Rp and Cp are represented

First Local Oscillator
The 1st LO is a multi-vibrator oscillator that takes an extemal
capacitance and inductance. It is voltage controlled to an
intemal varactor from an external loop filter and an on-board
phase-lock loop (PLL). The schematic in Figure 33 shows all
the basic parasitic elements of the internal circuitry. The 1st LO
internal component values have a tolerance of 15%. A typical
dc bias level on the LO Input and LO Output is 0.47 Vdc. The
curve in Figure 38 is the varactor control voltage range as it
relates to capacitance. It represents the expected capacitance
for a given control voltage of the MC13110.

Second local Oscillator
The 2nd lO is a CMOS oscillator similar to that used in the
MC145162. The 2nd LO is also used as the PLL reference
oscillator. It is designed to utilize an external parallel resonant
crystal.
'

II

PllDesign
The 1st LO level is important, as well as the choice of the
crystal for the PLL cJock reference and 2nd LO. A
fundamental, parallel resonant crystal specified with 7.0 to
12 pF load calibration capacitance is recommended. With
load calibration capacitance too high, the-crystal locks up
very slowly. If the LO power is less than -10 dBm, a
pull-down resistor at the 1st LO emitter (Pin 41) will
increase its drive level. The LO level is primarily a function
of the Colpitts capacitive voltage divider formed by the
capacitors between the base to emitter and the emiller to
ground.
The VCO gain factor expressed in MHzIV is indeed critical
to the phase noise performance. If this curve is too steep or
too sensitive to changes in control voltage, it may degrade
the phase noise performance. The external VCO circuit
design needs to consider the typical swing of the control
voltage and the corresponding linearity of the transfer
function, ~fosd!Ncontrol. In general, the higher the Q of the
VCO circuit inductor, the beller phase noise performance.
Adjacent channel rejection and isolation between the 1st
and 2nd mixers may be adversely affected due to layout
problems and difficulty in getting close to the package pins
with the grounds and decoupling capacitors on the RF VCC.
These system parameters must be evaluated for sensitivity
to layout and external component placement.
Intermodulation and adjacent channel performance
problems may also result from spurs around the 1st LO'which
may be caused by harmonics from the switched capacitor
clock driver and too low 1st LO drive level. The clock driver

8-178

operates at a frequency which is f(2nd LO)/(2 • (SCF
Divider». The harmonics are n • (f(2nd LO», where n can be
any positive integer. The current spikes of the SCF on the
supply lines cause the disturbance of the 1st LO. This may be
verified by observing the spurs on a spectrum analyzer while
changing the clock divider value. The spur frequencies will
change when the divider value is changed. The spurious
sideband problem may be avoided by changing the clock
divider value via software for each channel where it is a
problem. Certain channels are worse than others.
The PLL alignment procedure for the application circuit is
detailed in Appendix C. Refer to the MC145162 data sheet
for PlL design example.
limiting IF Amplifiers
The limiting IF amplifier typically has about 110 dB of gain;
the frequency response starts rolling off at 1.0 MHz.
Decoupling capacitors should be placed close to the
decoupling Pins 31 and 32 to ensure low noise and stable
operation. The IF input impedance is 1.5 k,Q for a suitable
match to 455 kHz ceramic filters.
RSSIICarrier Dtltect
The Received Signal Strength Indicator (RSSI) indicates
the strength of the IF level and the output is proportional to
the logarithm of the IF input signal magnitude. The RSSI
dynamic range is typically 80 dB. Connect 0.01 I1F to GND
from "RSSI" output pin to form the carrier detect filter. A
resistor needed to convert the RSSI current to voltage is
included in the internal circuit. An internal temperature
compensated reference current also improves the RSSI
accuracy over temperature.
"CD Out" is an open collector output; thus, an external
100"k,Q pull-up resistor to VCC is recommended. The carrier
detect threshold is programmable through the MPU
interface.
Quadrature Detector
The quadrature detector is coupled to the IF with an
external capaCitor between Pins 27 and 28; thus, the
recovered signal level output is increased for a given
bandwidth by increasing the capacitor. The external
quadrature component may be either a LCR resonant circuit,
which may be adjustable, or a ceramic resonator which is
usually fixed tuned.
The bandwidth performance of the detector is controlled
by the loaded Q of the LC tank circuit. The following equation
defines the components which set the detector circuit's
bandwidth:
(1) RT=QXL
wherE~

AT is the equivalent shunt resistance across the

LC
Tank. XL is the reactance of the quadrature inductor at the IF
frequency (XL = 2ItfL).

MOTOROLA ANALOG IC DEVICE DATA

MC13110
Specific 455 kHz quadrature LC components are
manufactured by Toko in various 5 mm, 7 mm and 10 mm
shielded cans in surface mount or leaded packages.
Recommended components such as, the 7 mm Toko, is used
in the application circuit. When minaturization is a key
constraint, a surface mount inductor and capacitor may be
chosen to form a resonant LC tank with the PCB and parasitic
device capacitance. The 455 kHz IF center frequency is
calculated by
(2) fc = [21t (LC p)1/2]- 1
where L is the parallel tank inductor. Cp is the equivalent
parallel capacitance of the parallel resonant tank circuit.
The following is a design example for a detector at 455 kHz
and a specific loaded Q. The loaded Q of the quadrature
detector is chosen somewhat less than the Q of the IF
bandpass. For an IF frequency of 455 kHz and an IF bandpass
of 20 kHz, the IF bandpass Q is approximately 23; the loaded
Q of the quadrature tank is chosen at 15.
Example:
Let the total extemal C = 180 pF. Note: the capacitance may
be split between a 150 pF chip capaCitor and a 5.0 to 25 pF
variable capacitor; this allows for tuning to compensate for
component tolerance. Since the extemal capacitance is much
greater than the internal device and PCB parasitic
capacitance, the parasitic capacitance may be neglected.

MOTOROLA ANALOG IC DEVICE DATA

Rewrite equation (2) and solve for L:
L = (0.159)2/(C fc 2)
L = 678 IlH ; Thus, a standard value is chosen:
L = 680 IlH (surface mount inductor)
The value of the total damping resistor to obtain the
required loaded Q of 15 can be calculated from equation (1):
RT = Q(21tfL)
RT = 15 (21t)(0.455)(680) = 29.5 kg
The internal resistance, Rint at the quadrature tank Pin 27
is approximately 100 kg and is considered in determining
the external resistance, Rex! which is calculated from
Rext = ((RT)(Rint))/(Rint - AT)
Rext = 41.8 kg; Thus, choose the standard value:
Rext= 39 kg
A ceramic discriminator is' recommended for the
quadrature circuit in applications where fixed tuning is
desired. The ceramic discriminator and a 22 k resistor are
placed from Pin 27 to VCC. A 10 pF capacitor is placed from
Pin 28 to 27 to properly drive the discriminator.
MuRata Erie has designed a resonator that is compatible
with the IC. For US applications the part number is
CDBM455C48. For Europe the part number is
CDBM450C48. Contact Motorola Analog Marketing for
performance data using muRata's parts.

FM Receiver
The FM receiver can be used with either a quad coil or a

designed to work for all country channels, including 25
channel U.S., without the need for any external switching
circuitry (see Figure 32).

Rx Audio Path (LPF/R x Gain Adjust!
Rx MutelExpandorNolume Control)
The Rx Audio signal path goes from "Rx Audio In" (Pin 24)
to "E Out" (Pin 46). The "Rx Audio In" input signal is ac
coupled. AC couple between "Scr Out" and "E In" (see
Figure 3).
Speaker Amp/SP Mute
The Speaker Amp is an inverting raiHo-;ail operational
amplifier. The noninverting input is connected to the internal VB
reference. Extemal resistors and capacitors are used to set the
gain and frequency response. The "SA In" Input is ac coupled.
MicAmp
The Mic Amp is an inverting rail-ter-rail operational amplifier
with noninverting input terminal connected to internal VB
reference. External resistors and capacitors are set to the gain
and frequency response. The ''Tx In" input is ac coupled.
Tx Audio Path (Compressor/ALCITx Mute!
Limiter/LPFITx Gain Adjust)
The Tx Audio signal path goes from "Tx In" (Pin 19) to
"Tx Out" (Pin 17). The "c In" input signal is ac coupled from
"Amp Out". The ALC (Automatic Level Control) provides a
"soft" limit to the output signal swing as the input voltage
increases slowly (i.e., a sine wave is maintained). The Limiter
circuit limits rapidly changing signal levels by clipping the
signal peaks. The ALC andlor Limiter can be disabled
through the MPU serial interface (see Figure 4).
Tx and Rx Audio
Each audio path contains a low-pass switched capacitor
filter (SCF). The control register must be set through the MPU
interface (Figure 11) for proper operation (Tx and Rx bits must
be set to"1 "). The SCF corner frequencies are proportional to
the SCF Clock. The SCF Clock Divider is programmable
through the MPU interface as follows: (SCF) F(2nd LO) I
(SCF Divider Value' 2). The LPF corner frequencies can be

selected in from the table in Figures 28 and 29 relative to the
2nd LO operating frequency.
PLL Voltage Regulator
The "PLL Vref' pin is the internal supply voltage for the Rx
and Tx PLL's. It is regulated to a nominal 2.5 V. The "VCC
Audio" pin is the supply voltage for the internal voltage
regulator. Two capacitors with 10 !!F and 0.1 !!F values must
be connected to the "PLL Vret" pin to filter and stabilize this
regulated voltage. The "PLL Vret" pin may be used to power
other IC's as long as the total external load current does not
exceed 1.0 mA. The tolerance of the regulated voltage is
initially ±8.0%, but is improved to ±4.0% after the internal
Bandgap voltage reference is adjusted electronically through
the MPU serial interface. The voltage regulator is turned off in
the Standby and Inactive modes to reduce current drain. In
these modes, the "PLL Vref' pin is internally connected to the
"VCC Audio" pin (Le., the power supply voltage is maintained
but is now unregulated).
Low Battery Detect
Two external precision resistor dividers are used to set
independent thresholds for two battery detect hysteresis
comparators. The voltages on "Refl" and "Ref2" are
compared to an internally generated 1.5 V reference voltage.
The tolerance of the internal reference voltage is initially
±6.0%. The Low Battery Detect threshold tolerance can be
improved by adjusting a trim-pot in the external resistor
divider. Alternately, the tolerance of the internal reference
voltage can be improved to ±1.5% through MPU serial
interface programming. The internal reference can be
measured directly at the "VB" pin. During final test of the
telephone, the VB internal reference voltage is measured.
Then, the internal reference voltage value is adjusted

electronically through the MPU serial interface to achieve the
desired accuracy level. The voltage reference register value
should be stored in ROM during final test so that it can be
reloaded each time the MC13111 IC is powered up. Low
Battery Detect outputs are open collector.
Power Supply Voltage
This circuit is used in a cordless telephone handset and
base unit. The handset is battery powered and can operate
on three NiCad cells or on 5.0 V supply.
·PLL Frequency Synthesizer General Description
Figure 5 shows a simplified block diagram of the
programmable universal dual phase locked loop (PLL). This
dual PLL is fully programmable through the MCU serial
interface and supports most country channel frequencies
including USA (25 ch), Spain, Australia, Korea, New
Zealand, U. K., Netherlands, France, and China.
The 2nd local oscillator and reference divider provide the
reference frequency for the receive (Rx) and transmit (Tx)
PLL loops. The programmed divider value for the reference
divider is selected based on the crystal frequency and the
desired Rx and Tx reference frequency values. Additional
divide by 25 and divide by 4 blocks are provided to allow for
generation of the 1.0 kHz and 6.25 kHz reference
frequencies required for the U. K. The 14-bit Tx counter is
programmed for the desired transmit channel frequency. The
14-bit Rx counter is programmed for the desired first local
oscillator frequency. All counters power up in the proper
default state for USA channel #21 (channel #6 for FCC 10
channel band) and for a 10.24 MHz reference frequency
crystal. Internal fixed capacitors can be connected to the tank
circuit of the 1st LO through microprocessor control to extend
the sensitivity of the 1st LO for U.S. 25 channel operation.

PLL VO Pin Specifications
The 2nd La, Rx and Tx PLL's, and MPU serial interface are
powered by the internal voltage regulator at the "PLL Vref'
pin. The "PLL Vref' pin is the output of a voltage regulator
which is powered from the "VCC Audio" power supply pin and
is regulated by an internal bandgap voltage reference.
Therefore, the maximum input and output levels for most PLL
1/0 pins (L02 In, L02 Out, Rx PO, Tx PO, Tx VCO) is the
regulated voltage at the "PLL Vref' pin. The ESD protection
diodes on these pins are also connected to "PLL Vret".
Internal level shift buffers are provided for the pins (Data, Clk,
EN, Clk Out) which connect directly to the microprocessor.
The maximum input and output levels for these pins is Vee.

The state of the EN pin when clocking data into the shift
register determines whether the data is latched into the
address register or a data register. Figure 9 shows the
address and data programming diagrams. In the data
programming mode, there must not be any clock transitions
when "EN" is high. The clock can be in a high state (default
high) or a low state (default low) but must not have any
transitions during the "EN" high state. The convention in
these figures is that latch bits to the left are loaded into the
shift register first.

Data Register Programming Mode

The MPU serial interface is fully operational within 100 Ils
after the power supply has reached its minimum level during
power-up (see Figure 10). The MPU Interface shift registers
and data latches are operational in all four power saving
modes; Inactive, Standby, Rx , and Active Modes. Data can
be loaded into the shift registers and latched into the latch
registers in any of the operating modes.

After data is loaded into the shift register, the data is
latched into the appropriate latch register using the "EN" pin.
This is done in two steps. First, an 8-bit address is loaded
into the shift register and latched into the 8-bit address latch
register. Then, up to 18-bits of data is loaded into the shift
register and latched into the data latch register specified by
the address that was previously loaded. Figure 5 shows the
timing required on the EN pin. Latching occurs on the
negative EN transition.

Reference Frequency Selection
The "L02In" and "L02 Ouf' pins form a reference oscillator
when connected to an external parallel-resonant crystal. The
reference oscillator is also the second local oscillator for the
RF Receiver. Figure 12 shows the relationship between
different crystal frequencies and reference frequencies for
cordless phone applications in various countries. "L02 In"
may also serve as an input for an externally generated
reference signal which is ac-coupled. The switched
capacitor filter 6-bit programmable counter must be
programmed for the crystal frequency that is selected since
this clock is derived from the crystal frequency and must be
held constant regardless of the crystal that is selected. The
actual switched capacitor clock divider ratio is twice the
programmed divider ratio since there is a fixed divide by 2.0
after the programmable counter.

Selecf' bits to "0". Then the fixed divider is set to "1" and the
Tx and Rx reference frequencies will be equal to the crystal
oscillator frequency divided by the programmable reference
counter value. The U.K. is a special case which requires a
different reference frequency value for T x and Rx. For U.K.
base operation, set "U.K. Base Select" to "1". For UK
handset operation, set "U.K. Handset Selecf' to "1".The
Netherlands is also a special case since a 2.5 kHz reference
frequency is used for both the Tx and Rx reference and the
total divider value required is 4096 which is larger than the
maximum divide value available from the 12-bit reference
divider (4095). In this case, set "U.K. Base Select" to "1" and
set "U.K. Handset Select" to "1". This will give a fixed divide
by 4 for both the Tx and Rx reference. Then set the reference
divider to 1024 to get a total divider of 4096.
Mode Control Register
Power saving modes, mutes, disables, volume control,
and microprocessor clock output frequency are all set by the
Mode Control Register. Operation of the Mode Control
Register is explained in Figures 14 through 21.

Reference Counter
Figure 13 shows how the reference frequencies for the Rx
and T x loops are generated. All countries except the U.K.
require that the T x and Rx reference frequencies be identical.
In this case, set "U.K. Base Select" and "UK Handset

Power Saving Operating Modes

Rx and Tx Audio Paths

When the MC13111 is used in a handset, it is important to
conserve power in order to prolong battery life. There are five
modes of operation; Active, Rx , Standby, Interrupt, and
Inactive. In Active mode, all circuit blocks are powered. In Rx
mode, all circuitry is powered down except for those circuit
sections needed to receive a transmission from the base. In
the Standby and Interrupt Modes, all circuitry is powered
down except for the circuitry needed to provide the clock
output for the microprocessor. In Inactive Mode, all circuitry is
powered down except the MPU interface. Latch memory is
maintained in all modes. Figure 16 shows the control register
bit values for selection of each power saving mode and
Figure 17 shows the circuit blocks which are powered in each
of these operating modes ..

NOTE: In Standby and Inactive Modes, "PLL vref remains powered but
is not regulated. It will fluctuate w~h Vee.

Inactive Mode Operation and Hardware Interrupt
In some handset applications it may be desirable to power
down all circuitry including the microprocessor (MPU). First
put the combo IC into the Inactive mode, which turns off the
MPU Clock Output (see Figure 18), and then disable the
microprocessor. In order to give the MPU adequate time to
power down, the MPU Clock output remains active for a
minimum of one reference counter cycle (about 200 lIS) after
the command is given to switch into the "Inactive" mode. An
external timing circuit should be used to initiate the turn-on
sequence. The "CD Ouf' pin has a dual function. In the Active
and Rx modes it performs the carrier detect function. In the
Standby and Inactive modes the carrier detect circuit is
disabled and the "CD Out" pin is in a "High" state due to the
external pull-up resistor. In the Inactive mode, the "CD Out"
pin is the input for the hardware interrupt function. When the
"CD Out" pin is pulled "low" by the external timing circuit, the
combo IC switches from the Inactive to the Interrupt mode
thereby turning on the MPU Clock Output. The MPU can then
resume control of the combo IC. The "CD Out" pin must
remain low until the MPU changes the operating mode from
Interrupt to Standby, Active or Rx modes.

MPU "Clk Out" Divider Programming
This pin is a clock output which is derived from the crystal
oscillator (2nd local oscillator). It can be used to drive a
microprocessor and thereby reduce the number of crystals
required. Figure 19 shows the relationship between the
crystal frequency and the clock output for different divider
values. Figure 20 shows the "Clk Out" register bit values.

cause problems in the system especially if the clock is a
square wave digital signal with large high frequency
harmonics. In order to minimize radiated noise, a 1.0 kil
resistor is included on--chip in series with the "Clk Out" output
driver. A small capacitor can be connected to the "Clk Ouf'
line on the PCB to form a single pole low pass filter. This filter
will significantly reduce noise radiated from the "Clk Ouf' line.
Volume Coritrol Programming
The volume control adjustable gain block can be
programmed in 2.0 dB gain steps from -14 dB to +16 dB. The
power-up default value is 0 dB. (See Figure 21.)

Gain Control Register

Tx and Rx Gain Programming

The gain control register contains bits which control the Tx
Voltage Gain, Rx Voltage Gain, and Carrier Detect threshold.
Operation of these latch bits are explained in Figures 22, 23
and 24.

The T x and Rx audio signal paths each have a
programmable gain block. If a Tx or Rx voltage gain other
than the nominal power-up default is desired, it can be
programmed through the MPU interface. Alternately, these
programmable gain blocks can be used during final test of the
telephone to electronically adjust for gain tolerances in the
telephone system as shown in Figure 23. In this case, the T x
and Rx gain register values should be stored in ROM during
final test so that they can be reloaded each time the combo
Ie is powered up.

Carrier Detect Threshold Programming
The ·CD Out" pin gives an indication to the microprocessor
if a carrier signal is present on the selected channel. The
nominal value and tolerance of the carrier detect threshold is
given in the carrier detect specification section of this
document. If a different carrier detect threshold value is
desired, it can be progra:mmed through the MPU interface as
shown in Figure 24. Alternately, the carrier detect threshold

can be ele9tronically adjus;ted during final test of the
telephone to reduce the tolerance of the carrier detect
threshold. This is done by measuring the threshold and then
by adjusting the threshold through the MPU interface. In this
case, it is necessary to store the carrier detect register value
in ROM so that the CD register can be reloaded each time the
combo IC is powered up.

Voltage Reference Adjustment
The internal 1.5 V Bandgap voltage reference provides the
voltage reference for the "BD1 Ouf' and "BD2 Ouf low
battery detect circuits, the "PLL Vre(' voltage regulator, the
"VB" reference, and all internal analog ground references.
The initial tolerance of the Bandgap voltage reference is
±S%. The tolerance of the internal reference voltage can be
improved to ±1.5% through MPU serial interface
programming.
During final test of the telephone, the battery detect
threshold is measured. Then, the internal reference voltage
value is adjusted electronically through the MPU serial
interface to achieve the desired accuracy level. The voltage
reference register value should be stored in ROM during final
test so that it can be reloaded each time the MC13111 is
powered up (see Figure 30).

Test Modes
Digital and analog test modes can be selected through the
4-bit Test Mode Register. In digital test mode, the ''Tx VCO"
input pin is multiplexed to the input of the counter under test
and the output of the counter under test is multiplexed to the
"Clk Ouf' output pin so that each counter can be individually
tested. Make sure test mode bits are set to "D's" for normal
operation. Digital test mode operation is described in
Figure 35. During normal operation and when testing the
T x Prescaler, the ''Tx VCO" input can be a minimum of 200
mVpp at 80 MHz and should be ao-coupled. For other test
modes, input signals should be standard logic levels of 0 to
2.5 V and a maximum frequency of 16 MHz.
The analog test modes enable separate testing of the
Compressor blocks as shown in Figure 36. Also, ALC Gain
options can be selected through analog test modes.

Power-Up Defaults for Control and Counter Registers
When the IC is first powered up, all latch registers are
initialized to a defined state. The device is initially placed in
the Rx mode with all mutes active. The reference counter is
set to generate a 5.0 kHz reference frequency from a 10.24
MHz crystal. The switched capacitor filter clock counter is set
properly for operation with a 10.24 MHz crystal. The audio
mode will come up in an undefined state and must be set to
a bit format shown in Figure 26 for proper operation. The T x
and Rx latch registers are set for USA Channel Frequency 21
(Channel 6 for previous FCC 10 Channel Band). Figure 37
shows the initial power-up states for all latch registers.

APPLICATIONS INFORMATION
Evaluation PC Board
The PCB should be double sided with a full ground plane
on one side; any leaded components are inserted on the
ground plane side. This affords shielding and isolation from
the circuit side of the PCB. The other side is the circuit side
which has the interconnect traces and the surface mount
components. In cases where cost allows, it may be benificial
to use multi layer boards.
The placement of certain components specified in the
application circuits is very critical. These components should
be placed first and the other less critical components are
fitted in last. In general, all RF paths should be kept as short
as possible, ground pins should be grounded at the pins and
VCC pins should have adequate decoupling to ground at the
pins. In mixed mode systems where digital and RF/Analog
circuitry are present, the VEE and VCC busses are isolated ac
-wise from each other.
Component Selection
The evaluation PC board is designed to accommodate
specific components, while in some cases it is versatile
enough to use components from various manufacturers and
coil types. The application circuit schematics specify
particular components that were used to achieve the results
shown in the typical curves and tables, but alternate
components should give similar results.
The MC13111 IC is capable of matching the sensitivity,
IMD, adjacent channel rejection, and other performance
criteria of a multi-chip analog cordless telephone system.
For the most part, the same external components are used
as in the multi-chip solution. In the following discussion,
various parts of the system are analyzed for best peformance
and cost tradeoffs. Specific recommendations are made
where certain components or circuit designs offer superior
performance. The system analyzed is the USA "CT-1"
cordless phone. (CT-D is a similar cordless application in
Europe.)
Input Matching/Sensitivity
The sensitivity of the IC is typically 0.561lVrms matched
with no preamp. To achieve suitable system performance, a
preamp and passive duplexer must be used. In production
final test, each section of the IC is separately tested to
guarantee its system performance in the specific
application. The preamp and duplexer (differential, matched
MOTOROLA ANALOG IC DEVICE DATA

input) yields typically -114 dBm 12 dB SINAD sensitivity
performance under full duplex operation.
The duplexer is important to achieve full duplex operation
without significant "de-sensing" of the receiver by the
transmitter. The combination of the duplexer and preamp
circuit will attenuate the transmitter power to the receiver by
over 60 dB. This will improve the receiver system noise figure
without giving up too much IMD intermodulation
performance.
The duplexer may be a single piece unit offered by
Shimida and Sansui products (designed for 10 channel CT-1
cordless phone) or a two piece solution offered by Toko
(designed for 25 channel operation). The duplexer frequency
response at the receiver port has a notch at the transmitter
frequency band of about 35 to 40 dB with a 2.0 to 3.0 dB
insertion loss at the receiver frequency band.
The preamp circuit utilizes a tuned transformer at the
output side of the amplifier. This transformer is designed to
bandpass filter at the receiver input frequency while rejecting
the transmitter frequency. The tuned preamp also improves
the noise performance by reducing the bandwidth of the pass
band and reducing the second stage contribution of the 1st
mixer. The preamp is biased at about 1.0 mA and 3.0 Vdc
which yields suitable noise figure and gain.
Mixers
The 1st and 2nd mixers are similar in design. Both are
double balanced to suppress the LO and the input
frequencies to give only the sum and difference frequencies
out. Typically the LO is suppressed about 40 to 60 dB. The
1st mixer may be driven either differentially or single ended.
The gain of the 1st mixer has a 3.0 dB corner at 20 MHz and
is used at a 10.7 MHz IF. It has an output impedance of
330 n and matches to a typical 10.7 MHz ceramic filter with
a source and load impedance of 330 n. A series resistor may
be used to raise the impedance for use with crystal filters
which typically have an input impedance much greater than
330 n. The 2nd mixer input impedance is typically 3.0 kn; it
requires an external 360 n parallel resistor for use with a
standard 330 n 10.7 MHz ceramic filter. The second mixer
output impedance is 1.5 kn making it suitable to match
455 kHz ceramic filters.

First Local Oscillator
The 1st LO is a multi-vibrator oscillator that takes an
external capacitance and inductance. It is voltage controlled
to an internal varactor from an external loop filter and an
on-board phase-lock loop (PLL). The schematic in Figure 33
shows all the basic parasitic elements of the internal circuitry.
The 1st LO internal component values have a tolerance of
15%. A typical dc bias level on the LO Input and LO Output is
0.45 Vdc. The temperature coefficient of the varactor is
+0.09%fOC. The curve in Figure 38 is the varactor control
voltage range as it relates to capacitance. It represents the
expected capacitance for a given control voltage of the
MC13111.

filters .

Second Local Oscillator
The 2nd LO is a CMOS oscillator Similar to that used in the
MC145162. The 2nd LO is also used as thePLL reference
oscillator. It is designed to utilize an external parallel resonant
crystal.
PLL DeSign
The 1st LO level is important, as well as the choice of the
crystal for the PLL clock reference and 2nd LO. A
fundamental, parallel resonant crystal specified with 1.0 to

8-208

12 pF load calibration capacitance is recommended. If the
load calibration capacitance is too high, the crystal locks up
very slowly. If the LO power is less than -10 dBm, a
pull-down resistor at the 1st LO emitter (Pin 41) will
increase its drive level. The LO level is primarily a function
of the Colpitts capacitive voltage divider formed by the
capacitors between the base to emitter and the emitter to
ground.
The VCO gain factor expressed in MHzIV is indeed critical
to the phase noise performance. If this curve is too steep or
too sensitive to changes in control voltage, it may degrade
the phase noise performance. The external VCO circuit
design needs to consider the typical swing of the control
voltage and the corresponding linearity of the transfer
function, Ll.fosdLl.Vcontrol. In general, the higher the Q of the
VCO circuit inductor, the better phase noise performance.
Adjacent channel rejection and isolation between the 1st
and 2nd mixers may be adversely affected due to layout
problems and difficulty in getting up close to the package pins
with the grounds and decoupling capacitors on the RF VCC.
These system parameters must be evaluated for sensitivity
to layout and external component placement.
Intermodulation' and adjacent channel performance
problems may also result from spurs around the 1st LO. This
may be caused by harmonics from the switched capacitor
clock driver and too low 1st LO drive level. The clock driver
operates at a frequency which is f(2nd LO)/(2 • (SCF
Divider)). The harmonics are n • (f(2nd LO)), where n can be
any positive integer. The current spikes of the SCF on the
supply lines cause the disturbance of the 1st LO. This may be
verified by observing the spurs on a spectrum analyzer while
changing the clock divider value. The spur frequencies will
change when the divider value is changed. The spurious
sideband problem may be avoided by changing the clock
divider value via software for each channel where it is a
problem. Certain channels are worse than others. Refer to
the MC145162 data sheet for PLL design example.

RSSIiCarrier Detect
The Received Signal Strength Indicator (RSSI) indicates
the strength of the IF level and the output is proportional to
the logarithm of the IF input signal magnitude. The RSSI
dynamic range is typically 80 dB. Connect 0.01 J.lF to GND
from "RSSI" output pin to form the carrier detect filter. A
resistor needed to convert the RSSI current to voltage is
included in the internal circuit. An internal temperature
compensated reference current also improves the RSSI
accuracy over temperature.
"CD Out" is an open collector output; thus, an external
100 kQ pull-up resistor to VCC is recommended. The carrier
detect threshold is programmable through the MPU
interface.

MOTOROLA ANALOG IC DEVICE DATA

MC13111
Quadrature Detector

The quadrature detector is coupled to the IF with an
external capacitor between Pins 27 and 28; thus, the
recovered signal level output is increased for a given
bandwidth by increasing the capacitor. The external
quadrature component may be either a LCR resonant circuit,
which may be adjustable, or a ceramic resonator which is
usually fixed tuned.
The bandwidth performance of the detector is controlled
by the loaded Q of the LC tank circuit. The following equation
defines the components which set the detector circuit's
bandwidth:

where RT is the equivalent shunt resistance across the LC
Tank. XL is the reactance of the quadrature inductor at the IF
frequency (XL =21tfL).
Specific 455 kHz quadrature LC components are
manufactured by Toko in various 5 mm, 7 mm and 10 mm
shielded cans in surface mount or leaded packages.
Recommended components such as, the 7 mm Toko, is used
in the application circuit. When minaturization is a key
constraint, a surface mount inductor and capacitor may be
chosen to form a resonant LC tank with the PCB and parasitic
device capacitance. The 455 kHz IF center frequency is
calculated by
(2) fc

=[21t (LCp)1/2j-1

where L is the parallel tank inductor. Cp is the equivalent
parallel capacitance of the parallel resonant tank circuit.
The following is a design example for a detector at 455 kHz
and a specific loaded Q. The loaded Q of the quadrature
detector is chosen somewhat less than the Q of the IF
bandpass. For an IF frequency of 455 kHz and an IF bandpass

MOTOROLA ANALOG IC DEVICE DATA

of 20 kHz, the IF bandpass Q is approximately 23; the loaded
Q of the quadrature tank is chosen at 15.
Example:
Let the total external C =180 pF. Note: the capacitance may
be split between a 150 pF chip capacitor and a 5.0 to 25 pF
variable capacitor; this allows for tuning to compensate for
component tolerance. Since the external capacitance is much
greater than the internal device and PCB parasitic
capacitance, the parasitic capacitance may be neglected.
Rewrite equation (2) and solve for L:
L = (0.159)2/(C fc 2)
L =678 ~H ; Thus, a standard value is chosen:
L = 680 ~H (surface mount inductor)
The value of the total damping resistor to obtain the
required loaded Q of 15 can be calculated from equation (1):
RT = Q(21tfL)
RT =15 (21t)(0.455)(680) =29.5 kn
The internal resistance, Rint at the quadrature tank Pin 27
is approximately 100 kn and is considered in determining
the external resistance, Rext which is calculated from
Rext =((RTHRint))/(Rint - AT)
Rext = 41.8 kn; Thus, choose the standard value:
Rext =39 kn
A ceramic discriminator is recommended for the
quadrature circuit in applications where fixed tuning is
desired. The ceramic discriminator and a 22 k resistor are
placed from Pin 27 to VCC. A 10 pF capaCitor is placed from
Pin 28 to 27 to properly drive the discriminator.
MuRata Erie has designed a resonator that is compatible
with the IC. For US applications the part number is
CDBM455C48. For Europe the part number is
CDBM450C48. Contact Motorola Analog Marketing for

FM Communications Receivers
The MC13135/MC13136 are the second generation of single chip, dual
conversion FM communications receivers developed by Motorola. Major
improvements in signal handling, RSSI and first oscillator operation have
been made. In addition; recovered audio distortion and audio drive have
improved. Using Motorola's MOSAICTM 1.5 process, these receivers offer
low noise, high gain and stability over a wide operating voltage range.
Both the MC13135 and MC13136 include a Colpitts oscillator, VCO tuning
diode, low noise first and second mixer and LO, high gain limiting IF, and
RSSI. The MC13135 is designed for use with an LC quadrature detector and
has an uncommitted op amp that can be used either for an RSSI buffer or as
a data comparator. The MC13136 can be used with either a ceramic
discriminator or an LC quad coil and the op amp is internally connected for a
voltage buffered RSSI output.
These devices can be used as stand-alone VHF receivers or as the lower
IF of a triple conversion system. Applications include cordless telephones,
short range data links, walkie-talkies, low cost land mobile, amateur radio
receivers, baby monitors and scanners.

TEST CIRCUIT INFORMATION
Although the MC13136 can be operated with a ceram.ic
discriminator, the recovered audio measurements for both
the MC13135 and MC13136 are made with an LC quadrature
detector. The typical recovered audio will depend on the
external circuit; either the Q of the quad coil, or the RC
matching network for the ceramic discriminator. On the
MC13136, an external capacitor between Pins 13 and 14can
be used with a quad coil for slightly higher recovered audio.
See Figures 10 through 13 for additional information.

Since adding a matching circuit to the RF input increases
the signal level to the mixer, the third order intercept (TOI)
point is better with an unmatched input (50 n from Pin 21 to
Pin 22). Typical values for both have been included in the
Electrical Characterization Table. TOI measurements were
taken at the pins with a high impedance probe/spectrum
analyzer system. TtJe first mixer input impedance was
measured at the pin with a network analyzer.

MC13135 MC13136
CIRCUIT DESCRIPTION
The MC13135/13136 are complete dual conversion
receivers. They include two local oscillators, two mixers, a
limiting IF amplifier and detector, and an op amp. Both
provide a voltage buffered RSSI with 70 dB of usable range,
isolated tuning diode and buffered LO output for PLL
operation, and a separate VCC pin for the first mixer and LO.
Improvements have been made in the temperature
performance of both the recovered audio and the RSS!.
VCC
Two separate VCC lines enable the first LO and mixer to
continue running while the rest of the circuit is powered down.
They also isolate the RF from the rest of the internal circuit.
Local Oscillators
The local oscillators are grounded collector Colpitts, which
can be easily crystal-controlled or VCO controlled with the
on-board varactor and external PLL. The first LO transistor is
internally biased, but the emitter is pinned-out and IQ can be
increased for high frequency or VCO operation. The collector
is not pinned out, so for crystal operation, the LO is generally
limited to 3rd overtone crystal frequencies; typically around
60 MHz. For higher frequency operation, the LO can be
provided externally as shown in Figure 16.
Buffer
An amplifier on the 1st LO output converts the
single-ended LO output to a differential signal to drive the
mixer. Capacitive coupling between the LO and the amplifier
minimizes the effects of the change in oscillator current on
the mixer. Buffered LO output is pinned-out at Pin 3 for use
with a PLL, with a typical output voltage of 320 mVpp at VCC
= 4.0 V and with a 5.1 k resistor from Pin 3 to ground. As seen
in Figure 14, the buffered LO output varies with the supply
voltage and a smaller external resistor may be needed for low
voltage operation. The LO buffer operates up to 60 MHz,
typically. Above 60 MHz, the output at Pin 3 rolls off at
approximately 6.0 dB per octave. Since most PLLs require
about 200 mVpp drive, an external amplifier may be required.

Mixers
The first and second mixer are of similar design. Both are
double balanced to suppress the LO and input frequencies to
give only the sum and difference frequencies out. This
configuration typically provides 40 to 60 dB of LO
suppression. New design techniques provide improved mixer
linearity and third order intercept without increased noise.
The gain on the output of the 1st mixer starts to roll off at
about 20 MHz, so this receiver could be used with a 21 MHz
first IF. It is designed for use with a ceramic filter, with an
output impedance of 330 n. A series resistor can be used to
raise the impedance for use with a crystal filter, which
typically has an input impedance of 4.0 kn. The second mixer
input impedance is approximately 4.0 kn; it requires an
external 360 n parallel resistor for use with a standard
ceramic filter.
Limiting IF Amplifier and Detector
The limiter has approximately 110 dB of gain, which starts
rolling off at 2.0 MHz. Although not designed for wideband
operation, the bandwidth of the audio frequency amplifier has
been widened to 50 kHz, which gives less phase shift and
enables the receiver to run at higher data rates. However,
care should be taken not to exceed the bandwidth allowed by
local regulations.
The MC13135 is designed for use with an LC quadrature
detector, and does not have sufficient drive to be used with a
ceramic discriminator. The MC13136 was designed to use a
ceramic discriminator, but can also be run with an LC quad
coil, as mentioned in the Test Circuit Information section. The
data shown in Figures 12 and 13 was taken using a muRata
CDB455C34 ceramic discriminator which has been specially
matched to the MC13136. Both the choice of discriminators
and the external matching circuit will affect the distortion and
recovered audio.
RSSIIOpAmp
The Received Signal Strength Indicator (RSSI) on the
MC13135/13136 has about 70 dB of range. The resistor
needed to translate the RSSI current to a voltage output has
been included on the internal circuit, which gives it a tighter
tolerance. A temperature compensated reference current
also improves the RSSI accuracy over temperature. On the
MC13136, the op amp on board is connected to the output to
provide a voltage buffered RSS!. On the MC13135, the op
amp is not connected internally and can be used for the RSSI
or as a data slicer (see Figure 17c).

CIRCUIT DESCRIPTION
figure and gain. Input and output matching may be achieved
at various frequencies using few extemal components (see
Application Circuit). Matching the LNA for maximum stable
gain (MSG) yields noise performance within a few tenths of a
dB of the minimum noise figure. Typical performance at
1.0 GHz is 17 dB gain and 1.8 dB noise figure for Vee at
3.0 to 5.0 Vdc.

General

The MC13141 Is a low power LNA, double-balanced
mixer. This device is designated for use as the front-end
section in analog and digital FM systems such as Digital
European Cordless Telephone (DECT), PHS, PCS, Cellular,
UHF and 800 MHz Special Mobile Radio (SMR), UHF
Family Radio Services and 902 to 928 MHz cordless
telephones. It features a mixer linearity control to preset or
auto preset or auto program the mixer dynamic range, an
enable function and buffered IF output for increased overall
gain. Further details are covered in the Pin Function
Description which shows the equivalent internal circuit and
external circuit requirements.

Mixer

The mixer is a double-balanced four quadrant multiplier
biased class AB allowing for programmable linearity control
via an external current source. An input third order intercept
point of 20 dBm may be achieved. All 3 ports of the mixer are
designed to work up to 1.8 GHz. The mixer has a 50 n
single-ended RF input and IF output buffer amplifier. The
linear gain of the mixer is approximately 7.0 dB with a SSE)
noise figure of 16 dB.

Current Regulation/Enable

Temperature compensating voltage independent current
regulators are controlled by the the enable function in which
"high" powers up the IC.

Local Oscillator

It requires an external local oscillator source at -10 dBm
input level to maximize the mixer gain.

Low Noise Amplifier (LNA)

The LNA is internally biased at low supply current
(approximately 2.0 mA emitter current) for optimal noise

Input Matching/Components

where:
F1 = the Noise Factor of the MC13142 LNA
G1 = the Gain of the LNA
F2 = the Noise factor of the RF Ceramic Filter
G2 = the Gain of the Ceramic Filter
F3 = the Noise factor of the Mixer

It is desirable to use a RF ceramic or SAW filter before
the mixer to provide image frequency rejection. The filter is
selected based on cost, size and performance tradeoffs.
Typical RF filters have 3.0 to 5.0 dB insertion loss. The PC
board layout accommodates both ceramic and SAW RF
filters which are offered by various suppliers such as
Siemens, Toko and Murata. Interface matching between the
LNA, RF filter and the mixer will be required. The interface
matching networks shown in the application circuit are
designed for 50 Q interfaces.
The LNA is conjugately matched to 50 g input and output
at 3.0 Vdc V CC. 17 dB gain and 1.8 dB noise figure is
typical at 881.5 MHz. The mixer measures 7.0 dB gain and
16 dB noise figure as shown in the application circuil.
Typical insertion loss of the Siemens SAW filter is 3.0 dB.

Note: the above terms are defined as linear relationships
and are related to the log form for gain and noise figure by the
following:
F = Log -1 [(NF in dB)/10] and similarly
G = Log -1 [(Gain in dB)/10]
Calculating in terms of gain and noise factor yields the
following:
F1 = 1.51 ; G1 = 50.11
F2=1.99 ; G2=0.5
F3= 39.8

System Noise Considerations
The block diagram shows the cascaded noise stages of
the MC13141 in the front-end receiver subsystem; it
represents the application circuit. In the cascaded noise
analysis the system noise equation is:

Thus, substituting in the equation for subsystem noise
factor:
Fsubsystem = 3.08 ; NFsubsystem = 4.9 dB
Overall Subsystem Gain = 21 dB

Fsystem = F1 + [{F2 -1)/G1] + [(F3-1)] / [(G1)(G2)]

(MSG) yields noise performance within a few tenths of a dB
of the minimum noise figure.
Mixer
The mixer is a double-balanced four quadrant multiplier
biased class AB allowing for programmable linearity control
via an external current source. An input third order intercept
point of 20 dBm may be achieved. All 3 ports of the mixer are
designed to work up to 1.8 GHz. The mixer has a 50 n
single--ended RF input and open collector differential IF
outputs. An on-board Local Oscillator transistor has the
emitter, base and collector pinned out to implement a low
phase noise VCO in various configurations. Additionally, a
buffered LO output is provided for operation with a frequency
synthesizer. The linear gain of the mixer is approximately
o dB with a SSB noise figure of 12 dB in the IF output circuit
configuration shown in the application example.
Local Oscillator
The on-chip transistor operates with coaxial transmission
line or LC resonant elements to over 2.0 GHz. Biasing is
done with a temperature compensated current source in the
emitter and a collector to base internal resistor of 7.6 kn;
however, an RFC from VCC to base is recommended. The
application circuit shows a voltage controlled Clapp oscillator
operating at center frequency of 975 MHz.

CIRCUIT DESCRIPTION
General
The MC13143 is a double-balanced Mixer. This device is
designated for use as the frontend section in analog and
digital FM systems such as Wireless Local Area Network
(LAN), Digital European Cordless Telephone (DECT), PHS,
PCS, GPS, Cellular, UHF and 800 MHz Special Mobile
Radio (SMR), UHF Family Radio Services and 902 to
928 MHz cordless telephones. It features a mixer linearity
control to preset or auto program the mixer dynamic range,
an enable function and a wideband IF so the IC may be
used either as a down converter or an up converter.
Current Regulation
Temperature compensating voltage independent current
regulators provide typical supply current at 1.0 mA with no
mixer linearity control current.

Mixer
The mixer is a unique and patented double-balanced four
quadrant multiplier biased class AB allowing for
programmable linearity control via an external current
source. An input third order intercept point of 20 dBm may be
achieved. All 3 ports of the mixer are deSigned to work up to
2.4 GHz. The mixer has a 50 n single-ended RF input and
open collector differential IF outputs (see Internal Circuit
Schematic for details). The linear gain of the mixer is
approximately -5.0 dB with a SSB noise figure of 12 dB.
Local Oscillator
The local oscillator has differential input configuration that
requires typically -10 dBm input from an external source to
achieve the optimal mixer gain.

APPLICATIONS INFORMATION
Evaluation PC Board
The evaluation PCB is very versatile and is intended to be
used across the entire useful frequency range of this device.
The PC board is laid out to accommodate all SMT
components on the circuit side (see Circuit Side Component
Placement View).
Component Selection
The evaluation PC board is designed to accommodate
specific components, while also being versatile enough to
use components from various manufacturers. The circuit side
placement view is illustrated for the components specified in
the application circuit. The Component Placement View
specifies particular components that were used to achieve
the results shown in the typical curves and tables.
Mixer Input
The mixer input impedance is broadband 50 Q for
applications up to 2.4 GHz. It easily interfaces with a RF
ceramic filter as shown in the application schematic.
Mixer Linearity Control
The mixer linearity control circuit accepts approximately
o to 2.3 mA control current. An Input Third Order Intercept
Point, IIP3 of 20 dBm may be achieved at 2.3 mA of control
current (approximately 7.0 mA of additional supply current).
Local Oscillator Inputs
The differential LO inputs are internally biased at
VCC - 1.0 VeE; this is suitable for high voltage and high gain
operation.
For low voltage operation, the inputs are taken to VCC
through 51 Q.
IF Output
The IF is a differential open collector configuration which is
designed to use over a wide frequency range for up
conversion as well as down conversion.
Input/Output Matching
It is desirable to use a RF ceramic or SAW filter before the
mixer to provide image frequency rejection. The filter is
selected based on cost, size and performance tradeoffs.
Typical RF filters have 3.0 to 5.0 dB insertion loss. The PC
board layout accommodates both ceramic and SAW RF
filters which are offered by various suppliers such as
Siemens, Toko and Murata.

MOTOROLA ANALOG IC DEVICE DATA

Interface matching between the RF input, RF filter and the
mixer will be required. The interface matching networks
shown in the application circuit are designed for 50 Q
interfaces.
Differential to single-ended circuit configuration is shown
in the test circuit. 6.0 dB of additional mixer gain can be
achieved by conjugately matching the output of the
MiniCircuits transformer to 50 Q at the desired IF frequency.
With narrowband IF output matching the mixer performance
is 3.0 dB gain and 12 dB noise figure (see Narrowband 49
and 83 MHz IF Output Matching Options). Typical insertion
loss of the Toko ceramic filter is 3.0 dB. Thus, the overall gain
of the circuit is 0 dB with a 15 dB noise figure.

MC13150
MC13150 CIRCUIT DESCRIPTION
General
The MC13150 is a very low power single conversion
narrowband FM receiver incorporating a split IF. This device
is designated for use as the backend in analog narrowband
FM systems such as cellular, 900 MHz cordless phones and
narrowband data links with data rates up to 9.6 k baud. It
contains a mixer, oscillator, extended range received signal
strength indicator (RSSI), RSSI buffer, IF amplifier, limiting IF,
a unique coilless quadrature detector and a device enable
function (see Package Pin Outs/Block Diagram).
Low Current Operation
The MC13150 is designed for battery and portable
applications. Supply current is typically 1.7 mAdc at 3.0 Vdc.
Figure 2 shows the supply current versus supply voltage.
Enable
The enable function is provided for battery powered
operation. The enabled pin is pulled down to enable the
regulators. Figure 3 shows the supply current versus enable
voltage, Venable (relative to VCC) needed to enable the
device. Note that the device is fully enabled at VCC -1.3 Vdc.
Figure 4 shows the relationship of enable current, lenable to
enable voltage, Venable.
Mixer
The mixer is a double-balanced four quadrant multiplier
and is designed to work up to 500 MHz. It has a single ended
input. Figure 5 shows the mixer gain and saturated output
response as a function of input signal drive and for -10 dBm
LO drive level. This is measured in the application circuit
shown in Figure 15 in which a single LC matching network is
used. Since the single-ended input impedance of the mixer is
200 Q, an alternate solution uses a 1:4 impedance
transformer to match the mixer to 50 Q input impedance. The
linear voltage gain of the mixer alone is approximately 4.0 dB
(plus an additional 6.0 dB for the transformer). Figure 6
shows the mixer gain versus the LO input level for various
mixer input levels at 50 MHz RF input.

MOTOROLA ANALOG IC DEVICE DATA

The buffered output of the mixer is internally loaded,
resulting in an output impedance of 1.5 kQ.
Local Oscillator
The on--chip transistor operates with crystal and LC
resonant elements up to 220 MHz. Series resonant, overtone
crystals are used to achieve excellent local oscillator stability.
3rd overtone crystals are used through about 65 to 70 MHz.
Operation from 70 MHz up to 200 MHz is feasible using the
on--chip transistor with a 5th or 7th overtone crystal. To
enhance operation using an overtone crystal, the intemal
transistor's bias is increased by adding an extemal resistor
from Pin 29 (in 32 pin OFP package) to VEE to keep the
oscillator on continuously or it may be taken to the enable pin
to shut it off when the receiver is disabled. -10 dBm of local
oscillator drive is needed to adequately drive the mixer
(Figure 6). The oscillator configurations specified above are
described in the application section.
RSSI
The received signal strength indicator (RSSI) output is a
current proportional to the log of the received signal
amplitude. The RSSI current output is derived by summing
the currents from the IF and limiting amplifier stages. An
external resistor at Pin 25 (in 32 pin OFP package) sets the
voltage range or swing of the RSSI output voltage. Linearity
of the RSSI is optimized by using external ceramic bandpass
filters which have an insertion loss of 4.0 dB. The RSSI circuit
is designed to provide 100+ dB of dynamic range with
temperature compensation (see Figures 7 and 23 which
show the RSSI response of the applications circuit).
RSSI Buffer
The RSSI buffer has limitations in what loads it can drive.
It can pull loads well towards the positive and negative
supplies, but has problems pulling the load away from the
supplies. The load should be biased at half supply to
overcome this limitation.

IF Amplifier
The first IF amplifier section is composed of three
differential stages. This section has internal dc feedback and
external input decoupling for improved symmetry and
stability. The total gain of the IF amplifier block is
approximately 42 dB at 455 kHz. Figure 8 shows the gain of
the IF amplifier as a function of the IF frequency.
The fixed internal input impedance is 1.5 kQ; it is designed
for applications where a 455 kHz ceramic filter is used and no
external output matching is necessary since the filter requires
a 1.5 kg source and load impedance.

Overall RSSI linearity is dependent on having total
midband attenuation of 10 dB (4.0 dB insertion loss plus 6.0
dB impedance matching loss) for the filter. The output of the
IF amplifier is buffered and the impedance is 1.5 kg.
Limiter
The limiter section is similar to the IF amplifier section
except that six stages are used. The fixed internal input
impedance is 1.5 kg. The total gain of the limiting amplifier
section is approximately 96 dB. This IF limiting amplifier
section internally drives the quadrature detector section.

Coilless Detector
The quadrature detector is similar to a PLL. There is an
internal oscillator running at the IF frequency and two
detector outputs. One is used to deliver the audio signal and
the other one is filtered and used to tune the oscillator.
The oscillator frequency is set by an external resistor at
the Fadj pin. Figure 9 shows the control current required for a
particular frequency; Figure 10 shows the pin voltage at that
current. From this the value of RF is chosen. For example,
455 kHz would require a current of around 50 IlA. The pin
voltage (Pin 16 in the 32 pin QFP package) is around 655mV
giving a resistor of 13.1 kQ. Choosing 12 kQ as the nearest
standard value gives a current of approximately 55 !lAo The
5.0 IlA difference can be taken up by the tuning resistor, RrThe best nominal frequency for the AFTout pin (Pin 17)
would be half supply. A supply voltage of 3.0 Vdc suggests a
resistor value of (1.5 - 0.655)Vl5!lA = 169 kQ. Choosing
150 kQ would give a tuning current of 3/150 k =20 !lAo From
Figure 9 this would give a tuning range of roughly 10 kHzlllA
or ± 100 kHz which should be adequate.
The bandwidth can be adjusted with the help of Figure 11.
For example, 1.0!lA would give a bandwidth of ± 13 kHz. The

II

So, for example, 150 k and 1.0 IlF give a 3.0 dB point of
4.5 Hz. The recovered audio is set by RL to give roughly
50mV per kHz deviation per 100 k of resistance. The dc level
can be shifted by RS from the nominal 0.68 V by the following
equation:
Detector DC Output = ((RL + RS)/RS) 0.68 Vdc

=

Thus, RS
RL sets the output at 2 x 0.68
RL 2RS sets the output at 3 x 0.68 2.0 V.

be ±13 kHz while the audio bandwidth will be approximately
±S.4 kHz due to an internal filter capacitor. This is verified in
Figure 13. For some applications it may be desirable that the
audio bandwidth is increased; this is done by reducing RB.
Reducing RB widens the detector bandwidth and improves
the distortion at high input levels at the expense of 12 dB

APPLICATIONS INFORMATION
Evaluation PC Board
The evaluation PCB is very versatile and is intended to be
used across the entire useful frequency range of this device.
The center section of the board provides an area for
attaching all SMT components to the circuit side and radial
leaded components to the component ground side (see
Figures 29 and 30). Additionally, the peripheral area
surrounding the RF core provides pads to add supporting
and interface circuitry as a particular application dictates.
There is an area dedicated for a LNA preamp. This
evaluation board will be discussed and referenced in this
section.

shown in Figures 27 and 28 for the application circuit in
Figure 15 and for the 83.616 MHz crystal oscillator circuit in
Figure 16.
Input Matching Components
The input matching circuit shown in the application circuit
schematic (Figure 15) is a series L, shunt C single L section
which is used to match the mixer input to 50 n. An
alternative input network may use 1:4 surface mount
transformers or BALUNs. The 12 dB SINAD sensitivity
using the 1:4 impedance transformer is typically -100 dBm
forfmod= 1.0 kHz andfdev =±5.0 kHz atfin =50 MHz and fLO
=50.455 MHz (see Figure 14).
It is desirable to use a SAW filter before the mixer to
provide additional selectivity and adjacent channel rejection
and improved sensitivity. SAW filters sourced from Toko (Part
# SWS083GBWA) and Murata (Part # SAF83.16MA51 X) are
excellent choices to easily interface with the MC13150 mixer.
They are packaged in a 12 pin low profile surface mount
ceramic package. The center frequency is 83.161 MHz and
the 3.0 dB bandwidth is 30 kHz.

Component Selection
The evaluation PC board is designed to accommodate
specific components, while also being versatile enough to
use components from various manufacturers and coil types.
The applications circuit schematic (Figure 15) specifies
particular components that were used to achieve the results
shown in the typical curves but equivalent components
should give similar results. Component placement views are

local Oscillators

A series LC network to ac ground (which is VCC) is
comprised of the inductance of the base lead of the on-chip
transistor and PC board traces and tap capacitors. Parasitic
oscillations often occur in the 200 to 800 MHz range. A small
resistor is placed in series with the base (Pin 28) to cancel the
negative resistance associated with this undesired mode of
oscillation. Since the base input impedance is so large, a
small resistor in the range of 27 to 68 (1 has very little effect
on the desired Butler mode of oscillation.
The crystal parallel capacitance, Co, provides a feedback
path that is low enough in reactance at frequencies of 5th
overtones or higher to cause trouble. Co has little effect near
resonance because of the low impedance of the crystal
motional arm (Rm-Lm-Cm). As the tunable inductor, which
forms the resonant tank with the tap capacitors, is tuned off
the crystal resonant frequency, it may be difficult to tell if the
oscillation is under crystal control. Frequency jumps may
occur as the inductor is tuned. In order to eliminate this
behavior an inductor, lo, is placed in parallel with the crystal.
Lo is chosen to resonant with the crystal parallel capacitance,
Co at the desired operation frequency. The inductor provides
a feedback path at frequencies well below resonance;
however, the parallel tank network of the tap capaCitors and
tunable inductor prevent oscillation at these frequencies.

HF & VHF Applications
In the application schematic, an external sourced local
oscillator is utilized in which the base is biased via a 51 (1
resistor to VCC. However, the on-chip grounded collector
transistor may be used for HF and VHF local oscillators with
higher order overtone crystals. Figure 16 shows a 5th
overtone oscillator at 83.616 MHz. The circuit uses a Butler
overtone oscillator configuration. The amplifier is an emitter
follower. The crystal is driven from the emitter and is coupled
to the high impedance base through a capacitive tap
network. Operation at the desired overtone frequency is
ensured by the parallel resonant circuit formed by the
variable inductor and the tap capacitors and parasitic
capacitances of the on-chip transistor and PC board. The
variable inductor specified in the schematic could be
replaced with a high tolerance, high Q ceramic or air wound
surface mount component if the other components have tight
enough tolerances. A variable inductor provides an
adjustment for gain and frequency of the resonant tank
ensuring lock up and start-up of the crystal oscillator. The
overtone crystal is chosen with ESR of typically 80 (1 and
120 (1 maximum; if the resistive loss in the crystal is too high
the performance of oscillator may be impacted by lower gain
margins.

Receiver Design Considerations

APPLICATIONS INFORMATION
Evaluation PC Board

The evaluation PCB shown in Figures 19 and 20 is very
versatile and is designed to cascade two ICs. The center
section of the board provides an area for attaching all surface
mount components to the circuit side and radial leaded
components to the component ground side of the PCB (see
Figures 17 and 18). Additionally, the peripheral area
surrounding the RF core provides pads to add supporting
and interface circuitry as a particular application dictates.
This evaluation board will be discussed and referenced in
this section.
Limiting Amplifier

Differential input and output ports interfacing the three
stage limiting amplifier provide a differential power gain of
typically 46 dB and useable frequency range of 300 MHz.
The IF gain flatness may be controlled by decoupling of the
internal feedback network at Pins 2 and 15.

MOTOROLA ANALOG IC DEVICE DATA

Scattering parameter (8-parameter) characterization of
the IF as a two port linear amplifier is useful to implement
maximum stable power gain, input matching, and stability
over a desired bandpass response and to ensure stable
operation outside the bandpass as well. The MC13155 is
unconditionally stable over most of its useful operating
frequency range; however, it can be made unconditionally
stable over its entire operating range with the proper
decoupling of Pins 2 and 15. Relatively small decoupling
capacitors of about 100 pF have a significant effect on the
wideband response and stability. This is shown in the
scattering parameter tables where S-parameters are shown
for various values of C2 and C15 and at VEE of - 3.0 and
-5.0Vdc.

MC13155
In the 8-parameters measurements, the IF is treated as a
two-port linear class A amplifier. The IF amplifier is
measured with a single-ended input and output configuration
in which the Pins 16 and 7 are terminated in the series
combination of a 47 n resistor and a 10 nF capacitor to VCC
ground (see Figure 14. 8-Parameter Test Circuit).
The 8-parameters are in polar form as the magnitude
(MAG) and angle (ANG). Also listed in the tables are the
calculated values for the stability factor (K) and the Maximum

Available Gain (MAG). These terms are related in the
followinj:l equations:
K= (1-181112,..1 82212+ I LlI2)/(21 812 8211)
where: I Lli = I 811 822 - 812 821 I.
MAG = 10 log I 8211 /1 8121 + 10 log I K-( K2_1)1/21
where: K > 1. The necessary and sufficient conditions for
unconditional stability are given as K > 1:
B1 = 1 + I 811 12 - I 822 12 - I Lll2 > 0

DC Biasing Considerations
The DC biasing scheme utilizes two VCC connections
(Pins 3 and 6) and two VEE connections (Pins 14 and 11).
VEEl (Pin 14) is connected internally to the IF and RSSI
circuits' negative supply bus while VEE2 (Pin 11) is connected
internally to the quadrature detector's negative bus. Under
positive ground operation, this unique configuration offers the
ability to bias the RSSI and IF separately from the quadrature
detector. When two ICs are cascaded as shown in the 70
MHz application circuit and provided by the PCB (see
Figures 17 and 18), the first MC13155 is used without biasing
its quadrature detector, thereby saving approximately 3.0
mAo A total current of 7.0 mA is used to fully bias each IC,
thus the total current ih the application circuit is
approximately 11 mAo Both VCC pins are biased by the same
supply. VCC1 (Pin 3) is connected internally to the positive
bus of the first half of the IF limiting amplifier, while VCC2 is
internally connected to the positive bus of the RSSI, the
quadrature detector circuit, and the second half of the IF
limiting amplifier (see Figure 15). This distribution of the VCC
enhances the stability of the IC.
RSSI Circuitry
The RSSI circuitry provides typically 35 dB of linear
dynamic range and its output voltage swing is adjusted by

selection of the resistor from Pin 12 to VEE. The RSSI slope
is typically 2.1 IJAIdB ; thus, for a dynamic range of 35 dB, the
current output is approximately 74 /-lA. A 47 k resistor will
yield an RSSI output voltage swing of 3.5 Vdc. The RSSI
buffer output at Pin 13 is an emitter-follower and needs an
external emitter resistor of 10k to VEE.
In a cascaded configuration (see circuit application in
Figure 16), only one of the RSSI Buffer outputs (Pin 13) is
used; the RSSI outputs (Pin 12 of each IC) are tied together
and the one closest to the VEE supply trace is decoupled to
VCC ground. The two pins are connected to VEE through a 47
k resistor. This reSistor sources a RSSI current which is
proportional to the signal level at the IF input; typically,
1.0 mVrms (- 47 dBm) is required to place the MC13155 into
limiting. The measured RSSI output voltage response of the
application circuit is shown in Figure 12. Since the RSSI
current output is dependent upon the input signal level at the
IF input, a careful accounting of filter losses, matching and
other losses and gains must be made in the entire receiver
system. In the block diagram of the application circuit shown
below, an accounting of the signal levels at pOints throughout
the system shows how the RSSI response in Figure 12 is
justified.

Cascading Stages
The limiting IF output is pinned-out differentially,
cascading is easily achieved by AC coupling stage to stage.
In the evaluation PCB, AC coupling is shown, however,
interstage filtering may be desirable in some applications. In
which case, the S-parameters provide a means to implement
a low loss interstage match and better receiver sensitivity.
Where a linear response of the RSSI output is desired
when cascading the ICs, it is necessary to provide at least
10 dB of interstage loss. Figure 12 shows the RSSI response
with and without interstage loss. A 15 dB resistive attenuator
is an inexpensive way to linearize the RSSI response. This
has its drawbacks since it is a wideband noise source that is
dependent upon the source and load impedance and the
amount of attenuation that it provides. A better, although
more costly, solution would be a bandpass filter designed to
the desired center frequency and bandpass response while
carefully selecting the insertion loss. A network topology

Quadrature Detector

The quadrature detector is coupled to the IF with internal
2.0 pF capacitors between Pins 7 and 8 and Pins 9 and 10.
For wideband data applications, such as FM video and
satellite receivers, the drive to the detector can be increased
with additional external capacitors between these pins, thus,
the recovered video signal level output is increased for a
given bandwidth (see Figure 11A and Figure 11 B).
The wide band performance of the detector is controlled by
the loaded Q of the LC tank circuit. The following equation
defines the components which set the detector circuit's
bandwidth:

(1 )
where: RT is the equivalent shunt resistance across the LC
Tank and XL is the reactance of the quadrature inductor at the
IF frequency (XL =27tfL).
The inductor and capacitor are chosen to form a resonant
LC Tank with the PCB and parasitic device capacitance at the
desired IF center frequency as predicted by:
fc = (21t "(LC p)) -1

(2)

where: L is the parallel tank inductor and Cp is the equivalent
parallel capacitance of the parallel resonant tank circuit.
The following is a design example for a wideband detector
at 70 MHz and a loaded Q of 5. The loaded Q of the
quadrature detector is chosen somewhat less than the Q of
the IF bandpass. For an IF frequency of 70 MHz and an
IF bandpass of 10.9 MHz, the IF bandpass Q is
approximately 6.4.
Example:
Let the external Cext = 20 pF. (The minimum value here
should be greater than 15 pF making it greater than the
internal device and PCB parasitic capacitance, Cint ~
3.0 pF).
Cp = Cint + Cext = 23 pF
Rewrite Equation 2 and solve for L:
L = (0.159)2 /(C p fc 2)
L = 198 nH, thus, a standard value is chosen.
L =0.22 !J.H (tunable shielded inductor).

MOTOROLA ANALOG IC DEVICE DATA

The value of the total damping resistor to obtain the
required loaded Q of 5 can be calculated by rearranging
Equation 1:
RT = Q(21tfL)
RT = 5 (21t)(70)(0.22) = 483.8 Q.
The internal resistance, Rint between the quadrature tank
Pins 8 and 9 is approximately 3200 Q and is considered in
determining the external resistance, Rext which is calculated
from:
Rext = «RT)(Rint))/ (Rint - RT)
Rext

= 570, thus, choose the standard value.

Rext = 560Q.
SAW Filter
In wideband video data applications, the IF occupied
bandwidth may be several MHz wide. A good rule of thumb is
to choose the IF frequency about 10 or more times greater
than the IF occupied bandwidth. The IF bandpass filter is a
SAW filter in video data applications where a very selective
response is needed (i.e., very sharp bandpass response).
The evaluation PCB is laid out to accommodate two SAW
filter package types: 1) A five-leaded plastic SIP package.
Recommended part numbers are Siemens X6950M which
operates at 70 MHz; 10.4 MHz 3 dB passband, X6951M
(X252.8) which operates at 70 MHz; 9.2 MHz 3 dB passband;
and X6958M which operates at 70 MHz, 6.3 MHz 3 dB
passband, and 2) A four-leaded T0-39 metal can package.
Typical insertion loss in a wide bandpass SAW filter is 25 dB.
The above SAW filters require source and load
impedances of 50 Q to assure stable operation. On the PC
board layout, space is provided to add a matching network,
such as a 1:4 surface mount transformer between the SAW
filter output and the input to the MC13155. A 1:4 transformer,
made by Coilcraft and Mini Circuits, provides a suitable
interface (see Figures 16, 17 and 18). In the circuit and
layout, the SAW filter and the MC13155 are differentially
configured with interconnect traces which are equal in length
and symmetrical. This balanced feed enhances RF stability,
phase linearity, and noise performance.

MC13156

Wideband FM IF System
The MC13156 is a wideband FM IF subsystem targeted at high
performance data and analog applications. Excellent high frequency
performance is achieved at low cost using Motorola's MOSAIC 1.5™ bipolar
proce~s, The MC13156 has an onboard grounded collector VCO transistor
that may be used with a fundamental or overtone crystal in single channel
operation or with a PLL in multichannel operation. The mixer is useful to
500 MHz and may be used in a balanced-differential, or single-ended
configuration. The IF amplifier is split to accommodate two low cost
cascaded filters. RSSI output is derived by summing the output of both IF
sections, A precision data shaper has a hold function to preset the shaper for
fast recovery of new data.
Applications for the MC13156 include CT-2, wideband data links and
other radio systems utilizing GMSK, FSK or FM modulation.

CIRCUIT DESCRIPTION
General
The MC13156 is a low power single conversion wide band
FM receiver incorporating a split IF. This device is designated
for use as the backend in digital FM systems such as CT-2
and wideband data links with data rates up to 500 kbaud. It
contains a mixer, oscillator, signal strength meter drive, IF
amplifier, limiting IF, quadrature detector and a data slicer
with a hold function (refer to Figure 8, Simplified Internal
Circuit Schematic).
Current Regulation
Temperature compensating voltage independent current
regulators are used throughout.
Mixer
The mixer is a double-balanced four quadrant multiplier
and is designed to work up to 500 MHz. It can be used in
differential or in single--ended mode by connecting the other
input to the positive supply rail.
Figure 4 shows the mixer gain and saturated output
response as a function of input signal drive. The circuit used
to measure this is shown in Figure 1. The linear gain of the
mixer is approximately 22 dB. Figure 9 shows the mixer gain
versus the IF output frequency with the local oscillator of
150 MHz at 100 mVrms LO drive level. The RF frequency is
swept. The sensitivity of the IF output of the mixer is shown in
Figure 10 for an RF input drive of 10 mVrms at 140 MHz and
IF at 10 MHz.
The single--ended parallel equivalent input impedance of
the mixer is Rp - 1.0 kn and Cp - 4.0 pF (see Table 1 for
details). The buffered output of the mixer is internally loaded
resulting in an output impedance of 330 n.
Local Oscillator
The on--chip transistor operates with crystal and LC
resonant elements up to 220 MHz. Series resonant, overtone
crystals are used to achieve excellent local oscillator stability.
3rd overtone crystals are used through about 65 to 70 MHz.
Operation from 70 MHz up to 180 MHz is feasible using the
on--chip transistor with a 5th or 7th overtone crystal. To
enhance operation using an overtone cristal, the internal
transistor's bias is increased by adding an external resistor
from Pin 23 to VEE. -10 dBm of local oscillator drive is
needed to adequately drive the mixer (Figure 10).
The oscillator configurations specified above, and two
others using an external transistor, are described in the
application section:
1) A 133 MHz oscillator multiplier using a 3rd overtone
crystal, and
2) A 307.8 to 309.3 MHz manually tuned, varactor controlled
local oscillator.
RSSI
The Received Signal Strength Indicator (RSS!) output is a
current proportional to the log of the received signal

MOTOROLA ANALOG IC DEVICE DATA

amplitude. The RSSI current output is derived by summing
the currents from the IF and limiting amplifier stages. An
external resistor at Pin 20 sets the voltage range or swing of
the RSSI output voltage. Linearity of the RSSI is optimized by
using external ceramic or crystal bandpass filters which have
an insertion loss of 8.0 dB. The RSSI circuit is designed to
provide 70+ dB of dynamic range with temperature
compensation (see Figures 6 and 7 which show RSSI
responses of the IF and Limiter amplifiers). Variation in the
RSSI output current with supply voltage is small (see
Figure 11).
Carrier Detect
When the meter current flowing through the meter load
resistance reaches 1.2 Vdc above ground, the comparator
flips, causing the carrier detect output to go high. Hysteresis
can be accomplished by adding a very large resistor for
positive feedback between the output and the input of the
comparator.
IF Amplifier
The first IF amplifier section is composed of three
differential stages with the second and third stages
contributing to the RSSI. This section has internal dc
feedback and external input decoupling for improved
symmetry and stability. The total gain of the IF amplifier block
is approximately 39 dB at 10.7 MHz. Figure 5 shows the gain
and saturated output response of the IF amplifier over
temperature, while Figure 12 shows the IF amplifier gain as a
function of the IF frequency.
The fixed internal input impedance is 1.4 kn. It is designed
for applications where a 455 kHz ceramic filter is used and no
external output matching is necessary since the filter requires
a 1.4 kn source and load impedance.
For 10.7 MHz ceramic filter applications, an external
430 n resistor must be added in parallel to provide the
equivalent load impedance of 330 n that is required by the
filter; however, no external matching is necessary at the input
since the mixer output matches the 330 n source impedance
of the filter. For 455 kHz applications, an external 1.1 kn
resistor must be added in series with the mixer output to
obtain the required matching impedance of 1.4 kn of the filter
input resistance. Overall RSSI linearity is dependent on
having total midband attenuation of 12 dB (6.0 dB insertion
loss plus 6.0 dB impedance matching loss) for the filter. The
output of the IF amplifier is buffered and the impedance is
290n.
Limiter
The limiter section is similar to the IF amplifier section
except that four stages are used with the last three
contributing to the RSSI. The fixed internal input impedance
is 1.4 kn. The total gain of the limiting amplifier section is
approximately 55 dB. This IF limiting amplifier section
internally drives the quadrature detector section.
