Figure 1-1. Physical Features of the SSE 5000 Radio
The SSE 5000 portable radio operates in the UHF Range 2 (450–488 MHz) frequency band. It can
be programmed with up to 96 channels. Earlier versions of the radio, which could be programmed
with up to 48 channels, can be upgraded to 96-channel capability via FLASHport®.

1.2

FLASHport®
The SSE 5000 radio utilizes Motorola’s FLASHport technology. FLASHport allows you to add
software that drives the radio’s capabilities, both at the time of purchase and afterwards. Previously,
changing a radio’s features and capabilities meant significant modifications, or buying a new radio.
Now the radio’s features and capabilities can be upgraded with FLASHport software, similar to how a
computer can be loaded with different software. For information on upgrading the radio’s features
using FLASHport, see the FLASHport User Guide (Motorola publication part number 6881094C35).

Chapter 2 Theory of Operation

This chapter provides a detailed circuit description of the SSE 5000 transceiver and VOCON boards.
When reading the theory of operation, refer to the appropriate schematic and component location
diagrams located in the back of this manual. This detailed theory of operation can help isolate the
problem to a particular component.
The SSE 5000 radio is a dual-mode (digital/analog), microcontroller-based transceiver incorporating
a digital signal processor (DSP). The microcontroller handles the general radio control, monitors
status, and processes commands input from the keypad or other user controls. The DSP processes
the typical analog signals, and generates the standard signaling digitally to provide compatibility with
existing analog systems. In addition, the DSP provides digital modulation techniques, utilizing voice
encoding techniques with error correction schemes. This provides the user with enhanced range and
audio quality, all in a reduced bandwidth channel requirement. It allows embedded signaling, which
can mix system information and data with digital voice to support a multitude of system features.
The SSE 5000 radio operates within the UHF range (450 to 488 MHz).

2.1

Major Assemblies
The SSE 5000 radio includes the following major assemblies (see Figure 2-1):
• VOCON Board — contains a dual-core processor which includes both the microcontroller unit
(MCU) and a digital signal processor (DSP) core, the processor’s memory devices, an audio
and power supply support integrated circuit (IC), a digital-support IC, and the audio power
amplifier.
• Transceiver (XCVR) Board — contains all transmit, receive, and frequency generation
circuitry, including the digital receiver back-end IC and the reference oscillator.
• Controls/Universal Flex — contains on/off/volume switch, channel select switch, push-to-talk
(PTT) switch, monitor button, several function-selectable switches, universal connector,
speaker, and microphone.
• Display — 112 pixels x 32 pixels bit-mapped, liquid-crystal display (LCD).

Theory of Operation: Mode of Operation

Mode of Operation
This section provides an overview of the radio’s receive and transmit operation in the analog mode.

2.2.1

Receiving
When the radio is receiving (see Figure 2-2), the signal travels from the antenna connector to the
transceiver board, passing through the antenna switch and the receiver front-end. The signal is then
filtered, amplified, and mixed with the first local-oscillator signal, generated by the voltage-controlled
oscillator (VCO).

Figure 2-2. Receiver Block Diagram
The resulting intermediate frequency (IF) signal is fed to the IF circuitry, where it is again filtered and
passed to the Abacus III digital back-end IC. In the digital back-end IC, the IF signal is mixed with the
second local oscillator to create the second IF at 2.25 MHz. In the back-end IC, a bandpass, sigmadelta, analog-to-digital converter then decodes the second IF signal, and outputs, on the radio’s
serial synchronous interface (SSI) bus, digital audio to the VOCON board.
On the VOCON board, the dual-core processor’s digital-signal processor (DSP) digitally filters the
PCM audio. The DSP decodes the information in the signal and identifies the appropriate destination
for it.
• For a voice signal, the DSP will route the digital voice data to the CODEC inside the audio and
power supply support IC, for conversion to an analog signal. The CODEC will then present the
signal to the receive audio pre-amplifier, then to the audio power amplifier, which drives the
speaker.
• For signaling information, the DSP will decode the message and pass it internally to the
microcontrol unit of the dual-core processor.

2.2.2

2-3

Transmitting
When the radio is transmitting, microphone audio is passed through gain stages to the CODEC,
where the signal is digitized (see Figure 2-3). The CODEC passes digital data to the DSP, where preemphasis and low-pass (splatter) filtering are done. The DSP passes this signal to a digital/analog
converter (DAC), where it is reconverted into an analog signal and scaled for application to the
voltage-controlled oscillator as a modulation signal.

Power Distribution
This section provides a detailed circuit description of the power distribution of the SSE 5000 radio.
In the SSE 5000 radio, power (B+) is distributed to two boards: the transceiver (RF) board and the
VOCON board (see Figure 2-4). In the case of a secure radio, B+ is also supplied to the encryption
module.

even when the On/Off/Volume knob has been turned to the off position, power remains on until the
microcontroller unit (MCU) completes its power-down, at which time the radio is physically powered
down.

DC Power Routing—VOCON Board
Raw B+, or unswitched B+, (UNSW_B+) is routed to connector J1 on the transceiver board, and then
on to P201 on the VOCON board. Here the UNSW B+ is forwarded to the radio’s control top
On/Off/Volume knob through connector J707 and a flex circuit, as well as to regulator U505 (VCC5).
The On/Off/Volume knob controls B+SENSE to a BJT switch, which in turn controls a power
MOSFET. The MOSFET is a solid-state power switch that provides SW B+ to the VOCON board, the
audio PA, the GCAP II IC (via GCAP_B+), and back to the transceiver board.
In the case of a secure radio model, SW B+ and UNSW B+ are also supplied to the encryption
module through connector J701.
The BJT switch is also under the control of the MCU via Vref from the GCAP II IC (U501). This allows
the MCU to follow an orderly power-down sequence when it senses that B+SENSE is off. This sense
is provided through MECH_SW_BAR (inverted B+SENSE).
The digital circuits in the VOCON board are powered from regulators located in the GCAP II IC
(U501), an external 5 Vdc regulator (VCC5, U505), and an external 1.55 Vdc regulator (VSW_1.55).
The GCAP II IC provides three supplies: VSW1, VSW2, and V2. These regulators are software
programmable.

Transceiver Board
The transceiver (XCVR) board performs the transmitter and receiver functions necessary to translate
between voice and data from the VOCON board and the modulated radio-frequency (RF) carrier at
the antenna. The transceiver board contains all the radio’s RF circuits for the following major
components:
• Receiver
• Transmitter
• Frequency Generation Unit (FGU)

interface, which is the control bus from the microprocessor. SSI is the serial synchronous interface

2.4.1.3 Antenna Ports
Antenna port J101 is a hot launch connector that interfaces to the antenna connector that is part of
the control top. This interface provides the launch mechanism for the antenna. Antenna port J102
provides RF to the accessory RF connector on the back of the SSE 5000 radio. This port provides
RF energy for tuning purposes, as well as RF for a public safety microphone.

2.4.1.4 Serial EEPROM
The serial, electrostatically erasable, programmable, read-only memory (EEPROM) has the
reference designator U4 on the SSE 5000 transceiver board. This IC holds all of the transceiver
tuning data. This allows transceivers to be tuned in the factory and installed in the field without
retuning.

2.4.1.5 Power Conditioning Components
DC power-conditioning components include zener diodes, capacitors, ferrite beads, a power
inductor, and the fuse. Diodes VR1 and VR2 provide over-voltage protection. Ferrite beads
(designated E1, E4, E101) and capacitors suppress electromagnetic interference from the
transceiver. The power-line filter consisting of L1, C13, and C14 suppresses digital noise from the
VOCON board switching power supplies that could degrade the transmitter spectral purity.
Pass transistor Q1 switches the battery voltage to the transceiver when control signal SWB+ or SB+
from the VOCON board is asserted high. This increases the transceiver’s immunity to conducted
interference that might be present on SWB+ or SB+, such as from switching voltage regulators on
the VOCON board.
Ground clip G9 makes contact between the transceiver board ground and the radio chassis. The
chassis connection is a necessary electrical reference point to complete the antenna circuit path.
Shields SH201 through SH702 and the tool hole appear on the schematic to show their connection
to ground.

2.4.2

Receiver
The SSE 5000 transceiver has a dual-conversion superheterodyne receiver. Figure 2-2 illustrates
the major receiver components:
• Receiver front-end
• Receiver back-end

2.4.2.1 Receiver Front-End
NOTE: Refer to Figure 2-2 for the receiver block diagram, Table 2-7 for local oscillator (LO) and first
IF information, and Figure 12-2 for the receiver front-end schematic.
The receiver front-end tunes to the desired channel and down converts the RF signal to the first
intermediate frequency (IF). Channel selection is by way of a tunable local oscillator, RXLO, from the
FGU.
Table 2-7. Local Oscillator and First IF Frequencies
UHF Range 2
(450–488 MHz)
LO Frequency Range

376.65–414.65 MHz

First IF Frequency

73.35 MHz

The receiver front-end consists of a preselector filter, an RF amplifier, a second preselector, mixer,
and an IF crystal filter. The SSE 5000 radio also contains a switchable attenuator between the
antenna switch and the first preselector filter. The RF amplifier is a discrete RF transistor with
associated circuitry. The mixer is a double-balanced, active mixer IC, coupled by transformers. The
receiver (RX) local oscillator (LO) is provided by the FGU.
2.4.2.1.1 Preselector Filters
The receiver front-end uses two discrete bandpass filters to achieve its required out-of-band
rejection. The first preselector filter precedes the RF amplifier, while the second preselector filter
follows the RF amplifier.

6881094C12-A

November 11, 2004

2-10

Theory of Operation: Transceiver Board

2.4.2.1.2 LNA (Low-Noise Amplifier)
The SSE 5000 radio uses a discrete transistor for the low-noise amplifier (Q430). A feedback
network between the collector and base improves stability and gain balance across the frequency
band. Input and output LC networks match the LNA impedance to 50 ohms.
A diode limiter (D400) protects the amplifier damage by strong input signals.
2.4.2.1.3 Mixer
The mixer (U470) down-converts the received RF to the first intermediate frequency (IF). The IF is
73.35 MHz. Low-side LO injection is used. Transformers are used as baluns to convert signals from
single-ended to balanced at pins MI, MIX, LO, and LOX. An output transformer converts the
balanced signal at pins MO and MOX to a single-ended output.
2.4.2.1.4 IF Filter
The IF filter (FL400) is a leadless, surface-mount, 3-pole, quartz crystal filter. This narrow bandpass
filter gives the radio its adjacent-channel and alternate-channel rejection performance.
Input and output LC networks match the filter impedance to 50 ohms.

2.4.2.2 Receiver Back-End
NOTE: Refer to Figure 2-2 for the receiver block diagram and Figure 12-3 for the receiver back-end
schematic.
The receiver back-end, which consists of the Abacus III (AD9874 IF digitizing subsystem) IC and its
associated circuitry, processes the down-converted IF signal to produce digital data for final
processing by the VOCON DSP.
2.4.2.2.1 Abacus III IC U500
The AD9874 is a general-purpose, IF subsystem that digitizes a low-level 10–300 MHz IF input with
a bandwidth up to 270 kHz. The output of the Abacus III IC is SSI data to the VOCON.
The signal chain of the AD9874 consists of a low-noise amplifier, a mixer, a bandpass sigma-delta
A/D converter, and a decimation filter with programmable decimation factor. An automatic gain
control (AGC) circuit provides the AD9874 with 12 dB of continuous gain adjustment. The high
dynamic range and inherent anti-aliasing provided by the bandpass sigma-delta converter allow the
AD9874 to cope with blocking signals 80 dB stronger than the desired signal.
Auxiliary blocks include frequency synthesizers for the second LO and sampling clock LO, as well as
an SPI port. The second LO uses a discrete external loop filter and VCO. The clock oscillator has an
external loop filter and resonator.

L547 and C542 match the input impedance to 50 ohms. Formatted SSI data is output to the VOCON
board on ports FS, DOUTA, and CLKOUT.
2.4.2.2.2 Second Local Oscillator
The second LO is controlled by the Abacus LO synthesizer, which mixes with IFIN to produce a 2.25
MHz final IF. The external VCO consists of Q502 and its bias network and frequency-determining
elements. Signal FREF is the 16.8 MHz reference from the FGU. Darlington transistor Q501 with
C550 and R501 form an active power-line filter.
The second LO frequency is 71.1 MHz by default or 75.6 MHz in special cases as needed to avoid
radio self-quieters. The loop filter is composed of R551, C558, C559, R552, and C512.
2.4.2.2.3 Sampling Clock Oscillator
The Abacus sampling clock synthesizer operates at 18 MHz = 8 x 2.25 MHz. The VCO uses an
internal transistor and external resonator. The resonator is composed of L503, C535, C929, and
D501.
The loop filter is composed of R512, C536, R514, C570, and C571.

2.4.3

Transmitter
NOTE: Refer to Figure 2-6 for the transmitter block diagram and Figure 12-4 for the transmitter
schematic.
The transmitter takes modulated RF from the FGU and amplifies it to the radio’s rated output power
to produce the modulated transmitter carrier at the antenna.
The transmitter consists of an RF driver IC that receives its input signal from the voltage-controlled
oscillator (VCO) and a high-power output transistor. Transmitter power is controlled by a power-

2.4.3.1 Power Distribution
To minimize voltage drop to the power amplifiers, net RAWB+ connects to power module Q107 and
the second stage of driver amplifier U102 through components having minimal series resistance—
ferrite beads and chokes only. During receive, no RF or DC bias is applied, and leakage current
through U102 and Q107 is less than 100 microamps.
At the rated transmitter power of 5 Watts, the radio consumes approximately 1800 mA, and at the
rated transmitter power of 2 Watts the radio consumes approximately 1100 mA.

2.4.3.2 Driver Amplifier
The driver amplifier IC (U102) contains two LDMOS FET amplifier stages and two internal resistor
bias networks. Pin 16 is the RF input. Modulated RF from the FGU, at a level of +3 dBm ±2 dB, is
coupled through a DC blocking capacitor to the gate of FET-1. An LC interstage matching network
connects the first stage output VD1 to the second stage input G2. The RF output from the drain of
FET-2 is pin 6 (RFOUT1). Gain control is provided by a voltage applied to pin 1 (VCNTRL). Typical
output power is about +27 dBm (500 mW) with VCNTRL at 5.0 V.
L109 and C113 are the interstage matching network. Components L105 and C110 match the output
impedance to 50 ohms; capacitor C107 is a DC block.

2.4.3.3 Power Amplifier Transistor Q107
The power amplifier transistor, Q107, is an LDMOS FET housed in a high-power, surface-mount, ring
package. To prevent thermal damage, it is essential that the heat sink of the power module be held in
place against the radio chassis. The input impedance-matching network uses discrete inductors and
capacitors. The low-pass output matching network uses both transmission lines and lumped LCs.
Drain bias is applied through E101 and L101. Gain is dynamically controlled by adjusting the gate
bias. The gate is insulated from the drain and source so that gate bias current is essentially zero.
The input impedance-matching network is L106, L107, C108, and C109. A transmission-line
structure and C137, C111, L110 and C112 form the output-matching network. Gate bias is applied
through R105 and L108.

2.4.3.4 Directional Coupler
A directional coupler senses the transmitter forward power as a control signal in the transmitter’s
automatic level control (ALC) loop. Isolated ports are terminated with external resistors.
The directional coupler is U101, a low-loss, bidirectional coupler.

2.4.3.5 Antenna Switch
The SSE 5000 has two antenna switches: one standard antenna switch and a remote antenna
switch.
The standard antenna switch is a quarterwave switch that determines whether the radio is in receive
or transmit mode. The standard antenna switch consists of part numbers D701, D702, C706, C704,
C701, C707, L702, L703, and R701. When the standard antenna switch is in receive mode, the
diodes D701 and D702 are unbiased and radio signals are able to travel to the receive front-end.
When the standard antenna switch is in transmit mode, radio signals travel from the transmitter to
the selected port and radio signals from the transmitter to the receive front-end are redirected by the
large impedance presented by L702 and C704. The receive front-end is also protected from the
transmitter because of the combined effect of the radio wave redirection and the short produced by
C703 when the standard antenna switch is enabled.
The circuitry that enables the standard antenna switch consists of part numbers L703, C707, and
U104. When the radio is in transmit mode, pin 32 (also known as ANO) on U104 provides
approximately 6.7 volts to diode D702. This voltage is dropped approximately 1.4 volts, or two diode
drops, and applied to R701. R701 sets the current through the antenna switch (approximately 14
mA). L703 and C707 are used as a DC bias network designed to only transmit DC signals.
The remote antenna switch is also a quarterwave switch, but this switch determines which antenna
the radio uses for transmit or receive. The remote antenna switch consists of part numbers D602,
D601, C724, C725, C726, C727, C728, L701, L704, L711, R703, R704, R705, Q702, and Q703.
When the radio is receiving from the standard antenna, no diodes are forward biased. In order to
activate the remote antenna port, the VOCON must supply 2.9 volts (+/– 3%) to pin 19 of the 26-pin
connector. Pin 19 is also known as TX_INH. TX_INH going high causes the voltage on the collector
of Q703 to become the voltage on the emitter. The voltage on the emitter for this circuit is zero volts.
The collector is connected to the gate of Q702, which in turn forces the voltage on the drain of Q702
to become the voltage on the source of Q702. The voltage on the source of Q702 is switched B+, or
battery voltage. Switched B+ is dropped approximately 1.4 volts, or two diode drops, and applied to
R705. R705 sets the current through the remote port switch (approximately 12 mA).
L701 and C724 are used as a DC bias network designed to only transmit dc signals. When the radio
is receiving or transmitting through the remote port, radio signals travel through diode D602. The
signals are directed away from the standard antenna by the large impedance presented by L704 and
C727. Accidental radiation through the standard antenna is prevented, because of the combined
effect of the radio wave redirection and the short produced by C725 when the remote port is
enabled.
NOTE: Part numbers C728 and L711 are used to resonate the parasitic capacitance created by diode
D602. The parasitic capacitance was creating a degradation in the transmit response through
the standard antenna port. Essentially, C728 is a DC block to prevent reverse biasing D602,
and L711 resonates with the parasitic capacitance of D602 to create a large impedance.

2.4.3.6 Harmonic Filter
RF from the power amplifier is routed through the coupler (U101), passed through the antenna
switch, passed through the remote port switch, and applied to a harmonic filtering network. The SSE
5000 harmonic filters are five-pole elliptical low-pass filters.

6881094C12-A

November 11, 2004

2-14

Theory of Operation: Transceiver Board

The initial design utilizes a cutoff frequency of 750 MHz, even though the actual design cutoff
frequency is 488 MHz. The reasoning behind using a significantly higher cutoff frequency is due to
the lower frequency response of realized circuits. The design tables used for the filter synthesis can
be located in the Handbook of Filter Synthesis (Zverev, pp. 218–219), where θ = 47.0. This design
was chosen because the attenuation at the stop band was the closest to the desired ratio for the
SSE 5000 design.
The remote port harmonic filter consists of parts C709, C710, C711, C712, C713, L706, and L707.
The antenna port harmonic filter consists of parts C716, C717, C718, C719, C720, L709, and L710.
The filters are optimized for the impedance match seen for their respective ports and terminations.
NOTE: Capacitor C720 was changed to 2pF, because this value improved the radiated response of
the radio with the antenna removed. Also, Capacitors C710 and C711 were increased in order
to remove a spur located at the (2*LO)-IF frequency point (680.075 MHz), where LO is
450.0625 MHz – 73.35 MHz and IF is 73.35 MHz. Essentially, C710 and C711 decreased the
cutoff frequency of the remote port harmonic filter.

2.4.3.7 RF Detector D101
Schottky diode D101 is used as a forward-power detector. Forward-coupled RF from the power
amplifier is converted to a DC voltage. Detector output is a positive DC voltage, proportional to the
amplitude of the RF signal at the input, and is applied to the ALC input of the PCIC.

2.4.3.8 Power-Control IC (PCIC) U104
The PCIC, U104, contains all of the digital, and most of the analog, circuits needed to control the
transmitter power amplifier. Host control is through a 3-wire, smart SPI interface. Pin descriptions are

2.4.3.8.1 Power and Control
Since U104 is powered from switched B+, it makes its own regulated 4.5 Vdc to power the internal
logic. The supply input is V5EXT at pin 17, and the output is V45 at pin 16. ANO at pin 32 is the
control signal to the RX/TX antenna switch control circuit.
2.4.3.8.2 Automatic Level Control (ALC)
In TX mode, the PCIC disables the receiver, turns on the transmitter, and controls the TX power
level. The automatic level control (ALC) circuit operates as follows:
The power level is set by programming an internal DAC to a calibrated reference voltage. D/A
settings for the power set points were determined during radio tuning and stored in EEPROM. An
internal op-amp compares the D/A reference voltage to the detector voltage at pin 1(RFIN) (TP101)
and produces an error signal output. This signal is buffered by another op-amp, configured as a lowpass filter, or integrator, to produce the INT output at pin 4 (TP111).
This INT output supplies voltage to drive the gain control pins of amplifiers U102 and Q107.
Resistors R105 and R106 determine the voltage ratio between U102 pin 1 (VCNTRL) and the Q107
gate. Transient response during key-up and key-down is controlled by the power amplifier rise and
fall times. External capacitors at pins CI, CJ, and CL, along with internal programmable resistors,
determine the ALC time constants.
2.4.3.8.3 Temperature Cut Back
The PCIC contains a temperature cut-back circuit to protect the power amplifier (PA) from thermal
damage that might result from incorrect assembly of the radio. External sensor U103 is a linear
temperature-to-voltage transducer, placed near the hottest spot in the radio: power module Q107.

6881094C12-A

Theory of Operation: Transceiver Board

The output is a DC voltage at pin 2 (VOUT) proportional to the temperature at pin 3 (GND). VOUT is
750 mV at 25°C and increases by 10 mV/°C. The PCIC temperature cut-back threshold is
programmed to correspond to 85 or 90°C. Above this threshold, the ALC gradually cuts back the
transmitter until it is fully turned off at 125°C. The slope of cut-back versus temperature is set by
external resistor R111. Diode D104 clamps TEMP to a voltage not much less than VG (pin 15), about
1.3 V, to improve the transient response of the cut-back circuit.

2.4.4

Frequency Generation Unit (FGU)
The frequency-generation function is performed by several ICs, two voltage-controlled oscillators
(VCOs) (one transmit and one receive), and associated circuitry. The reference oscillator provides a
frequency standard to the fractional-N frequency synthesizer (FracN) IC, which controls the VCOs
and VCO buffer IC (VCOBIC). The VCOBIC amplifies the VCO signal to the correct level for the next
stage.
NOTE: Refer to Figure 12-5 and Figure 12-6 for the FGU schematics.

2.4.4.1 Reference Oscillator Y200
The radio’s frequency stability and accuracy derive from the Voltage-Controlled TemperatureCompensated Crystal Oscillator (VCTCXO), Y200. This 16.8 MHz oscillator is controlled by the
voltage from the WARP pin of the FracN IC, U202, that can be programmed through a serial
peripheral interface (SPI). The oscillator output at pin 3 is coupled through capacitor C234 to the
FracN synthesizer reference oscillator input and through C236 to the non-invertive input of the opamp, U201.
Op-amp U201 buffers the 16.8 MHz output to the VOCON board. Components L205 and C214 form
a low-pass filter to reduce harmonics of the 16.8 MHz.
The Digital-to-Analog Converter (DAC) IC, U203, and Switched Capacitors Filter (SCF) IC, FL200,
form the interface between radio's DSP and the analog modulation input of the FracN IC.

2.4.4.2 Fractional-N Frequency Synthesizer (FracN) IC U202
The FracN IC, U202, is a mixed-mode, Motorola-proprietary, CMOS, fractional-N frequency
synthesizer with built-in dual-port modulation. The SSE 5000 radio uses a low-voltage version of the
device, sometimes called LVFracN, for compatibility with the 3 V logic used throughout the radio.
The FracN IC incorporates frequency division and comparison circuitry to keep the VCO signals
stable. The FracN IC is controlled by the MCU through a serial bus. All of the synthesizer circuitry is
enclosed in rigid metal cans on the transceiver board to reduce interference effects.
Separate power supply inputs are used for the various functional blocks on the IC. Inductors L203
and L204 provide isolation between supply pins 20 (AVDD) and 36 (DVDD) connected to Vdd3. Host
control is through a three-wire, smart SPI interface (pins 7, 8, and 9) with a bi-directional data pin.
FracN functions include frequency synthesis, reference clock generation, modulation control, voltage
multiplication and filtering, and auxiliary logic outputs.
2.4.4.2.1 Synthesizer
Frequency synthesis functions include a dual-modulus prescaler, a phase detector, a programmable
loop divider and its control logic, a charge pump, and a lock detector output. Fractional-N synthesizer
IC principles of operation are covered in detail in the manufacturers’ literature. No similar discussion
will be attempted here.
2.4.4.2.2 Clocks
U202, pin 23 (XTAL1), is the 16.8 MHz reference oscillator input from the VCTCXO (Y200).

2.4.4.2.3 Modulation
To support many voice, data, and signaling protocols, the SSE 5000 radio must modulate the
transmitter carrier frequency over a wide audio frequency range, from less than 10 Hz up to more
than 6 kHz. The FracN supports audio frequencies down to zero Hz by using dual-port modulation.
The audio signal at pin 10 (MODIN) is internally divided into high- and low-frequency components,
which modify both the synthesizer dividers and the external VCOs through signal MODOUT (pin 41).
The IC is adjusted to achieve flat modulation frequency response during transmitter modulation
balance calibration using a built-in modulation attenuator.
2.4.4.2.4 Voltage Multiplier and Superfilter
Pins 12 (VMULT3) and 11 (VMULT4) together with diode arrays D201 and D202 and their associated
capacitors form the voltage multiplier. The voltage multiplier generates 11.5 Vdc to supply the phase
detector and charge-pump output stage at pin 47 (VCP).
The superfilter is an active filter that provides a low-noise supply for the VCOs and VCOBIC. The
input is regulated 5 Vdc from Vdd5 at pin 30 (SFIN). The output is superfiltered voltage FSF at pin 28
(SFOUT).
The output from pin 15 (VMULT1) is used as a clock for the SCF IC, FL200.

2.4.4.3 Loop Filter
The components connected to pins 43 (IOUT) and 45 (IADAPT) form a 3rd-order, RC low-pass filter.
Current from the charge-pump output, IOUT, is transformed to voltage VCTRL, which modulates the
VCOs. Extra current is supplied by IADAPT for rapid phase-lock acquisition during frequency
changes. The lock detector output pin 4 (LOCK) goes to a logic “1” to indicate when the phased-lock
loop is in lock.

2.4.4.4 VCO Buffer IC (VCOBIC)
The VCOBIC (U250) is an analog IC containing two NPN transistors for use as oscillators, an activebias circuit, transmitter and receiver buffer amplifiers, and switching circuitry. The VCOBIC has three
RF outputs:
• TX_OUT (pin 10)—the modulated transmitter carrier
• RX_OUT (pin 8)—the receiver first LO
• PRESC_OUT (pin 12)—connected to FracN pin 32 (PREIN) through a matching circuit
Transmit/receive control is a single 5.0 Vdc logic input, TRB_IN (pin 19). When TRB_IN is low, the
receiver buffer is active and the transmitter circuits are disabled. The converse is also true.
This radio uses two external, discrete, varactor-tuned, Colpitts VCOs based on transistors Q211 and
Q215. Bias current to the VCOs is switched on and off by transistors Q214 and Q210, which are
controlled by FracN outputs AUX2 and AUX4. Transistors packged in Q301 form a 3.3 Vdc-to-5 Vdc
logic-level shifter for the signal from the FracN AUX3 pin to the VCOBIC.

board.

select line (pin 3) are at 2.9V logic levels. See Section 2.5.3: “Display Module” on page 2-31 for
details on the display module.

2.5.2

Functional Blocks

2.5.2.1 Controller and Memory
The controller and memory section contains the following components:
• Dual-core processor (U401), which acts as both the microcontroller unit (MCU) and the digital
signal processor (DSP) for the radio
• Static RAM (SRAM) IC (U403), a volatile device, which is used as working memory and shares
the address and data bus with the Flash memory device
• Flash memory IC (U402), which contains host firmware, DSP firmware, and some codeplug
data
2.5.2.1.1 Dual-Core Processor U401

processor (DSP) in one IC package. It comes in a 256-pin, ball-grid array (BGA) package with 1mm
pitch solder balls. Most of the pins on the dual-core processor operate from the 3 V supply. A 1.55 V
supply is used for the core voltage and the clock amplifier module. The remaining pins of the
processor use a 2.9 V supply. The External Interface Module (EIM) utilizes a 1.85 V supply.
There are also two system clocks provided to the dual-core processor.

Theory of Operation: VOCON Board

Microcontroller Unit (MCU)
The MCU portion of the dual-core processor controls receive/transmit frequencies, power levels,
display, and other radio functions, using either direct logic control or serial communications paths to
the devices. The microcontrol unit executes a stored program located in the FLASH memory device.
Data is transferred to and from memory by the microcontrol unit data bus. The memory location from
which data is read, or to which data is written, is selected by the address lines. The microcontrol unit
requires a 16.8 MHz clock and a 32.768 kHz clock.
The MCU portion of the dual-core processor has 22.5k x 32 bits of internal RAM and 1k x 32 bits of
internal ROM, which is used for the bootstrapping code. The MCU has several peripherals including
an External Interface Module (EIM), the Multiple Queue Serial Peripheral Interface (MQSPI), two
Universal Asynchronous Receiver/Transmitter (UART) modules, and the One-Wire Interface
module. The MCU communicates internally to the DSP through the MCU/DSP Interface (MDI).
External Interface Module (EIM)
The External Interface Module (EIM) is the MCU interface to the SRAM U403 and Flash Memory
U402. The EIM lines include 24 external address lines, 16 external bi-directional data lines, 6 chip
selects lines, read/write line, and output enable line among others. All of the EIM lines operate at 1.8V logic levels, and the EIM operates at the MCU clock speed.
Multiple Queue Serial Peripheral Interface (MQSPI)
The Multiple Queue Serial Peripheral Interface (MQSPI) is the MCUs programming interface to other
ICs. The dual-core processor has two independent SPI busses, and each has its own clock line (test
points SCKA and SCKB), data-out line (test points MOSIA and MOSIB), and data-in line (test points
MISOA and MISOB). There are 10 SPI chip selects (SPICS) that are programmable to either SPI A,
the transceiver board SPI bus, or to SPI B, the dedicated VOCON SPI bus.
The devices on the SPI A bus include the PCIC and FracN IC on the SPICS4 (R131), the Abacus III
IC on SPICS5 (R126), an analog-to-digital converter (ADC) on SPICS6 (R133), and the serial
EEPROM on SPICS7 (R132). The two SPI B chip selects are for the GCAP II IC U501 on SPICS2
(R539) and the digital-support IC U301 on SPICS3. All of the SPI module lines operate at GPIO
voltage logic levels.
There are several devices on the transceiver board that only have one bi-directional SPI data line.
Components U404, U405, and U406 are configurable by MCU GPIO pin TOUT13 (MISOA_SEL) to
route the data line to the appropriate pin on the dual-core processor depending on which SPI device
is being accessed.
Universal Asynchronous Receiver/Transmitter (UART)
The dual-core processor has two Universal Asynchronous Receiver/Transmitter (UART) modules.
UART1 handles the RS232 lines while UART 2 is connected to the SB9600 lines. Each UART has a
receive data line (URXD), a transmit data line (UTXD), and hardware flow control signals (RTS–
request to send) and (CTS–clear to send). All UART lines operate at GPIO voltage logic levels. The
translation to 5 V logic levels for the accessory side connector is discussed in Section 2.5.2.3.1:
“Digital-Support IC U301” on page 2-26.
One-Wire Interface
The MCU has a One-Wire Interface module that is used to communicate to a One-Wire device like a
USB cable or a smart battery using the Dallas Semiconductor protocol. This module uses a GPIO
voltage logic level.

Digital Signal Processor (DSP)
The DSP portion of the dual-core processor performs signaling and voice encoding and decoding, as
well as audio filtering and volume control. The DSP performs Private-Line/Digital Private-Line (PL/
DPL) encode and alert-tone generation. The DSP transmits pre-emphasis on analog signals, and
applies a low-pass (splatter) filter to all transmitted signals. The DSP controls squelch, deviation, and
executes receiver and transmitter filtering. The DSP executes a stored program located in the
FLASH memory device.
The DSP requires a 16.8 MHz clock. The DSP uses the 16.8 MHz clock to generate a 256 kHz clock
and an 8 kHz frame synchronization signal that is supplied to the CODEC. Additionally, the DSP
requires clock and frame synchronization from the Abacus III digital back-end IC on the transceiver
board to generate another clock and frame synchronization signal, and these signals are supplied to
transmit DAC on the transceiver board.
The DSP has 84k x 24 bits of program RAM and 62k x 16 bits of data RAM. It has its own set of
peripherals including the Baseband Interface Port (BBP), the DSP Timer module, and the Serial
Audio CODEC Port (SAP). Additionally, the DSP shares some peripherals with the MCU, including
the USB interface and the General Purpose Input/Output module (GPIO).
Baseband Interface Port (BBP)
The Baseband Interface Port (BBP) module is the DSP’s serial synchronous interface (SSI) to the
transceiver board. The BBP has independent sections for the receiver and the transmitter. The
receiver BBP pins include the receive data pin SRDB (U703 pin 4), the receive clock signal pin SC0B
(U705 pin 4), and the receive frame synchronization (sync) signal pin SC1B (U704 pin 4). The
transmitter's BBP pins include the transmit data pin STDB (R717), the transmit clock signal pin
SCKB (R715), and the transmit frame sync signal pin SC2B (R711). All BBP lines use GPIO voltage
logic levels.
DSP Timer Module
While the BBP receive clock and frame sync signals are supplied by the Abacus III IC from the
transceiver board, the BBP transmit clock and frame sync signals are generated by the DSP Timer.
The BBP receive clock, connected to the DSP Timer input pin T10, is reference used to generate the
BBP transmit clock and frame sync signals. These two signals, along with the BBP transmit data
signal, are connected to the DAC on the transceiver board.
Serial Audio CODEC Port (SAP)
The Serial Audio CODEC Port (SAP) module is the DSP’s serial synchronous interface (SSI) to the
audio CODEC on the GCAP II IC. The SAP also interfaces with the encryption module.
The SAP interface consists of four signals including the SAP clock line pin SCKA (component R405),
the SAP frame sync line pin SC2A (component R406), the SAP receive data line pin SRDA
(component R402), and the transmit data line pin STDA (component R403).
The SAP clock is generated by the dual-core processor U401, and is a 256 kHz, 2.9 V peak-to-peak
square wave. The SAP frame sync signal is generated by the dual-core processor U401, and is an 8
kHz, 2.9 V peak-to-peak square wave.
Universal Serial Bus (USB)
The dual-core processor USB peripheral, shared by the MCU and the DSP, provides the required
buffering and protocol to communicate on the Universal Serial Bus. The dual-core processor
supports USB slave functionality.
The receive data path is routed from the discrete USB receiver (U302 pin 8) and is buffered by U308.
Single-ended positive data is generated at U302 pin 3 and is sent to the dual-core processor pin
URXD_RTS.

2-22

Theory of Operation: VOCON Board

USB data minus comes from U302 pin 4 and this signal is sent to URXD1 of the dual-core processor.
General-Purpose Input/Output (GPIO) Module
The General-Purpose Input/Output (GPIO) module is shared by the MCU and the DSP. This module
consists of four 16-pin bi-directional ports and a 15 pin bi-directional port. While some of the pins on
these ports are being used for other functions (UART, SPI, SAP, BBP, and Interrupt pins), the
remaining pins can be programmed to become GPIOs that can be used by either the DSP or the
MCU. Each GPIO pin has up to 8 alternate output functions and up to 4 alternate input functions.
This allows for the GPIO pins to be routed internally to pertinent dual-core processor modules.
Additionally, the GPIO module adds selectable edge-triggered or level-sensitive interrupt
functionality to the GPIO pins. Some examples of GPIO pins include the Audio PA control signals
(EXT_SPKR_SEL, AUDIO_PA_EN, and AUDIO_MODE_SEL), the EEPOT control signals
(EEPOT_INC*, EEPOT_U_D*, EEPOT_CS*, and EEPOT_CS_EXT*), and the LED control signals
(RED_LED and GREEN_LED).
System Clocks
Two main clocks are provided to the dual-core processor. The first clock, a 16.8 MHz sine wave,
comes from the RF interface connector P201 pin 7. This is the most important clock, since it is used
internally to generate the clocks for both the MCU and DSP cores, as well as most of the peripherals.
It is conditioned by the clock buffer circuit, which includes Q601, R603, R605, R615, L601, C606,
C609, R608, and C607. The output of this buffer (C452) goes to the dual-core processor CKIH pin,
as well as to the digital-support IC REF_16_IN.
The other clock supplied to the dual-core processor is a 3 V peak-to-peak 32.768 kHz square wave
(32 kHz test point). It is generated by the digital-support IC U301 internal oscillator and an external
32.768 kHz crystal Y301, and is supplied to the CKIL pin on the dual-core processor. While not as
widely used as the 16.8 MHz clock, the 32.768 kHz clock is needed by some components in the
dual-core processor, including the reset circuitry.
2.5.2.1.2 Static RAM (SRAM) U403
The static RAM (SRAM) IC U403 is an asynchronous, 1 MB, CMOS device that is capable of 70 ns
access speed. It is supplied with 1.8 volts. The SRAM has its 19 address lines and 16 data lines
connected to the EIM of the dual-core processor through the Address(23:0) and Data(15:0) busses.
The SRAM has an active-high chip select CS2 that is tied directly to the 1.8 V supply and an active
low chip select CS1 that is connected to the EIM CS2_N pin (test point CS2). When the SRAM CS1
pin is not asserted, the SRAM is in standby mode, which reduces current consumption.
Two other control signals from the EIM that change the mode of the SRAM are the read/write signal,
R/W, and the output enable signal, OE. The R/W of the EIM is connected to the SRAM EN_WE pin
(test point R_W), while the OE signal from the EIM is connected to the SRAM EN_OE pin. The
SRAM is in read mode when the EN_WE pin is not asserted and the EN_OE pin is asserted. The
SRAM is in write mode when the EN_WE pin is asserted, regardless of the state of the EN_OE pin.
The other SRAM pins are the lower-byte enable pin LB and the upper-byte enable pin UB. These
pins are used to determine which byte (LB controls data lines 0-7 and UB controls data lines 8-15) is
being used when there is a read or a write request from the dual-core processor. The LB pin is
controlled by the EIM EB1_N signal, while the UP pin is controlled by the EB0_N signal.
2.5.2.1.3 FLASH Memory U402
The Flash memory IC is an 8 MB CMOS device with simultaneous read/write or simultaneous read/
erase operation capabilities with 70 ns access speed. It is supplied with 1.8 volts. The Flash memory
has its 22 address lines and 16 data lines connected to the EIM of the dual-core processor through

the Address(23:0) and Data(15:0) busses. The Flash memory contains host firmware, DSP firmware,
and codeplug data with the exception of the tuning values that reside on the transceiver board’s
serial EEPROM. The Flash memory IC is not field repairable.
The RESET_OUT of the dual-core processor is at a GPIO voltage logic level. Components D401 and
R401 are used to convert the voltage down to a 1.8 V logic level, and this 1.8 V reset signal is fed to
the Flash RESET pin. When this pin is asserted (active low logic), the Flash is in reset mode. In this
mode, the internal circuitry powers down, and the outputs become high-impedance connections.
The Flash active-low chip select pin, EN_CE, is connected to the active-low CS0_N pin (CS0 test
point) of the EIM. When the EN_CE is not asserted, the Flash is in standby mode, which reduces
current consumption.
Several other active-low control pins determine what mode the Flash memory is in: the address valid
pin ADV that is connected to the EIM LBA_N signal, the output enable pin EN_OE that is connected
to the EIM OE_N signal, and the write enable pin EN_WE that is connected to the EIM EB1_N
signal. For read mode, the ADV and EN_OE pins are asserted while the EN_WE pin is not asserted.
When the EN_WE is asserted and the EN_OE pin is unasserted, the Flash operates in the write
mode.

Theory of Operation: VOCON Board

The audio and power supply IC (GCAP II IC) has many functions. It supplies most of the voltages
used on the VOCON board, while external linear regulators supply 5 Vdc and 1.55 Vdc. It also has
microphone audio amplifiers, switching between internal and accessory microphones, multiplexing
capability for receive and transmit audio, filtering, voltage regulators, a real-time clock (RTC), and the
audio CODEC. The audio CODEC performs analog-to-digital and digital-to-analog conversions on
audio signals. The GCAP IC also has an analog/digital converter (ADC), which is used to monitor
volume setting and battery voltage. The GCAP II IC is programmed by the dual-core processor.
The audio pre-amplifier and the audio PA condition the received audio signal from the analog output
of the CODEC from the GCAP IC before the audio is routed to the speaker. The dual EEPOT sets
the gain of the microphone signal. The audio PA is sourced from the battery, and both of these
devices are programmed by the dual-core processor.
2.5.2.2.1 GCAP II IC U501
The GCAP II IC is a mixed-signal (analog and digital) IC that provides control, audio, and voltage
regulation functionality. It comes in a 100-pin, ball-grid array (BGA) package with 0.8 mm pitch solder
balls. The GCAP II IC is supplied with switched battery voltage GCAP_B+ (R581).
Voltage Regulation
The GCAP II IC contains several voltage regulators that are used in the design of the VOCON board:
VSW1, VSW2, and V2. The VSW1 regulator is a programmable switching regulator that uses the
switched battery voltage as its input on pin PSRC1. The output voltage of VSW1 (R502) is
programmable by the dual-core processor U401 through the SPI bus. The initial output of VSW1 is
3.2 volts, which is then programmed to 3.8 volts. The VSW1 voltage is supplied to the RF Interface
connector P201 pin 15 and to the input pins of the VSW2 and V2 regulators.
The VSW2 regulator is a SPI programmable switching regulator that uses VSW1 as its input on pin
PSRC2. The initial output of VSW2 (R501) is 2.2 volts, which is then programmed to 1.875 volts
(referred to as 1.8 volts throughout this document). The VSW2 voltage is supplied to the dual-core
processor (core voltage and the EIM voltage), the SRAM U403, the Flash memory U402, and the
display module connector J301
The V2 regulator is a SPI programmable linear regulator that uses VSW1 as its input on pin VIN2.
The initial output of V2 (R560) is 2.775 volts, which is then programmed to 2.9 volts. The V2 voltage
is supplied to the dual-core processor (I/O ring - SPI, BBP, SAP, UART, GPIO, etc.), the digitalsupport IC U301, the EEPOT U509, the display module connector J301, and the many discrete
components that interface with the dual-core processor and the digital-support IC.
MCU Interface
The GCAP II IC has a four-wire, SPI connection to the dual-core processor (SPI B). The SPI B clock
is connected to the SPI_CLK pin (test point SCKB). The SPI B MOSI line is connected to the
SPI_DW pin (test point MOSIB). The SPI B MISO line is connected to the SPI_DR pin (test point
MISOB). The GCAP SPI B chip-select signal is connected to the CE pin (R539). Through this
interface, the dual-core processor can program the voltage regulators, the CODEC, the transmit and
receive audio filters and amplifiers, as well as read information from the ADC and the real-time clock.
The GCAP II IC has an 8-bit ADC with general-purpose six channels and four voltage-monitoring
channels. The six general-purpose analog-to-digital (A/D) channels are assigned to the display
backlight button on the control head (AD0), the monitor volume (AD5); the two-position toggle switch
(AD1); the OPT_SEL_IN (AD2) (for determining accessory attachment), VOCON board ID (AD3),
and RF board ID (AD4). Battery voltage is also monitored by the ADC. The dual-core processor
activates and reads the A/D values through the SPI bus.

Audio Circuitry
A 13-bit CODEC, internal to the GCAP II IC and programmable by the dual-core processor through
the SPI bus, converts microphone audio into a digital bit stream for processing by the DSP. The
CODEC also converts receive audio data that was processed by the DSP into an analog audio signal
for amplification to a speaker. The CODEC interfaces to the DSP through the 4-wire SAP bus. The
CODEC clock, which is 256 kHz and is supplied to the DCLK pin. The CODEC 8 kHz CODEC frame
synchronization signal is supplied to the FSYNC pin. The CODEC transmit data signal is on the TX
pin, while the CODEC receive data signal is on the RX pin. For the CODEC to operate with those
clock and frame sync signals, a 13 MHz clock (R302), generated by the digital-support IC, is
supplied to the GCAP CLK_IN pin.
The GCAP II IC contains internal amplification, filtering, and multiplexing functionality for both
receive and transmit audio. These functions are dual-core processor-programmable through the SPI
bus. The input for the internal microphone audio (R540) is the MICIN_NEG pin, while the input for
the external microphone audio (R566) is the AUX_MIC_NEG pin. The output for the speaker audio is
the EXTOUT pin (C533).
2.5.2.2.2 5 V Regulator U505
The 5 V regulator uses UNSW_B+ as its input voltage. The digital-support IC WDI line controls the
regulator’s SHUTDOWN pin. The 5 V supply (R503) is used by the digital-support IC U301, audio
preamplifier U502, microphone bias circuitry (R531 and R563), digital-support IC protection diodes,
bi-directional voltage translators, battery data-line isolation circuitry, and ESD protection circuitry.
2.5.2.2.3 1.55 V Regulator
The 1.55 V regulator is made up of the following components: R600, Q600, U600, C601, C600,
R601, R602, R617, C605, C603, and C604. This circuit uses VSW1 to bias the regulator while
VSW2 sources the current. This voltage is used by the dual-core processor U401 for its core voltage
and clock amplifier.
2.5.2.2.4 Audio Pre-Amplifier U502
The audio pre-amplifier U502 is a single-package, 5-pin, op-amp supplied with 5 volts. This pre-amp
is an active low-pass filter and provides a fixed gain, which is selected by the components R551 and
R537. The input (U502 pin 4) of stage is the EXTOUT pin from the GCAP II IC, while the output
(U502 pin 1) of this stage goes to the audio PA.
2.5.2.2.5 Audio Power Amplifier U503
The audio PA U503 consists of two BTL amplifiers, complementary outputs, and control logic. Each
of the amplifiers has a fixed gain—the external audio PA gain is set by components R553 and R554,
while the internal audio PA gain is set by components R549 and R550.
The MODE pin (U503 pin 4) voltage determines the operation of the amplifier. That voltage is
controlled by the dual-core processor GPIO lines AUDIO_PA_EN (to Q505) and
AUDIO_MODE_SEL (to Q506). Table 2-9 describes how the dual-core processor GPIO lines
configure the audio PA.
The SELECT pin (U503 pin 6) is used to switch the audio path between internal and external
speaker. The voltage on that pin is determined by the EXT_SPKR_SEL line from the dual-core
processor and the Q505 transistor. When the voltage at the SELECT pin is high (B+), the audio is
routed to the internal speaker lines. When the voltage at the SELECT pin is low (V_select < 0.5V),
the audio is routed to the external speaker lines.

2.5.2.2.6 EEPOT U509
The EEPOT is a digitally programmable potentiometer with 256 taps and a total resistance of 50
Kohms. This 10-pin package contains two independent potentiometers, one for each microphone
line. The EEPOT resistance values are programmed by the dual-core processor GPIOs
EEPOT_INC* (U509 pin 9) and EEPOT_U_D* (U509 pin 2). The EEPOT_INC* signal increments the
resistance value up or down, which depends on the EEPOT_U_D* signal. The EEPOT_CS* line
(U509 pin 10) is asserted when the internal microphone gain is being changed. Similarly, the
EEPOT_CS_EST* (U509 pin 1) is asserted for external microphone gain changes. The EEPOT is
supplied with voltage from the GCAP II V2 regulator.

2.5.2.3 Interface Support
The interface support section consists of the following:
• Digital-support IC U301
• ESD protection circuitry
• Universal connector interface circuitry
The digital-support IC contains a USB transceiver, switching logic between RS232 and boot data
path, One- Wire side connector support, and several clock generators. The digital-support IC is
programmed by the dual-core processor.
ESD protection devices include zener diodes and low-capacitance ESD suppressors.
Side connector interface circuitry includes current-limiting resistors and noise-suppressing shunt
capacitors.
2.5.2.3.1 Digital-Support IC U301
NOTE: See Figure 12-14. NCN6186_ VOCON Flipper Circuit on page 12-20.
The digital-support IC U301 is an application-specific integrated circuit (ASIC) device designed for
the SSE 5000. It is contained in a 64-pin µBGA package with 0.8 mm pitch solder balls. The digitalsupport IC is supplied with 5 V and the processor’s GPIO voltage. It is supplied with a 16.8 MHz
clock from the transceiver board. Using this clock, the digital-support IC generates a 13 MHz clock
for the GCAP II IC. Additionally, the digital-support IC uses a crystal to generate the 32 kHz clock
used by the dual-core processor and GCAP II IC.
The digital-support IC supports many functions, including the radio’s universal (accessory) side
connector interface, One-Wire option detect support, watchdog timer, and 32 kHz oscillator with
CMOS output. It also monitors the position of the on/off switch and controls the shutdown of the
regulators on the GCAP II IC.
The digital-support IC is programmable by the dual-core processor through the SPI bus.

2-27

Side Connector Interface, Logic Level Translation, and Boot Data Path Control
The digital-support IC facilitates the interface to the radio's side connector. Some of the side
connector lines are at 5 V logic levels, so the digital-support IC converts those lines to GPIO voltage
logic levels to interface to the dual-core processor. These lines include the SB9600 bus busy line
LH_BUSY (R242), and the RS 232 CTS (R245).The SB9600 data line uses an external, bi-direc
tional, voltage translation circuit that includes Q304, D302, R328, R329, R330, U303, and C314.
USB Transceiver
The USB transceiver, U302, is capable of transmitting and receiving serial data at a rate of 12
megabits per second. The differential USB data comes from the side connector, through the 33-ohm
resistors R252 and R253 and the isolation switch Q301, and then to the VP and VM pins on U302.
The USB receive interface from the digital-support IC to the dual-core processor is as follows: VP
routed to PA2_USB_VPIN VM, routed to USB_VMI_RXD, and the differential decoded data is output
at the RCV pin and goes to the dual-core processor URTS1 pin.
The USB transmitter is enabled when the SUSPND and OE_EN signals are both driven low by the
dual-core processor. The single-ended data is output from the dual-core processor on the UTXD1
pin and goes to VO_VPO on U302. The data is driven out differentially on the DPOS and DNEG
pins, which go to the side connector. The dual-core processor sends the single-ended zero signal
from pin PC0_USB_VMOUT to the FSE0_VMO pin on U302.
When a USB cable is detected, Q302 pin 2 goes high. This controls the isolation switch Q301 so that
the data that is on those lines are routed to the USB transceiver. If a USB cable is not detected, the
Q302 pin is low and the USB transceiver is isolated. This isolation is done primarily because the
RS232 data lines are 5 V lines, so the switch protects the transceiver since it operates at a lower
voltage, and the USB data lines to the side connector also act as the RS232 lines.
On the VOCON board, the USB transceiver on the digital-support IC is not used. Instead, a discrete
USB transceiver U310 is used. The transceiver is provided with 5 V and 2.9 V. The 5 V powers an
internal 3.3 V voltage regulator on the transceiver, which is used as the voltage for the USB data pins
D+ and D- as well as the VPU pin. The 2.9 V is used by the remaining pins as they interface to the
dual-core processor U401.
One-Wire Support
New options and accessories that attach to the side connector are identified by the dual-core
processor using the One-Wire protocol. The One-Wire pin on the side connector serves as the OneWire data pin. This signal is connected to the ONE_WIRE_OPT pin. This pin is connected to the
dual-core processor One-Wire bus ONE_WIRE_UP through an internal isolation switch controlled by
a dual-core processor GPIO line to the digital-support IC ONE_WIRE_EN_X pin. This isolation is
needed to prevent possible contention on the One-Wire bus when a smart battery is attached to the
radio.
These new accessories are to ground, CTS (TP208), of the side connector. When this occurs, the
digital-support IC pin KVL_USB_DET_X is asserted and the dual-core processor detects the
change. The dual-core processor then asserts the ONE_WIRE_EN_X pin on the digital-support IC to
connect the side connector One-Wire line to the dual-core processor One-Wire bus. In the case of
the USB cable, the dual-core processor reads the One-Wire data from the cable and, upon
determining that a USB cable is attached, programs the digital-support IC for USB mode.

Theory of Operation: VOCON Board

Watchdog Timer
The digital-support IC monitors the position of the radio’s On/Off switch on the BP_SEN_X pin, and
that signal is located on Q508 pin 3. If the voltage on pin 3 is ground, then the radio is turned on. If
the voltage on pin 3 is 3 volts, then the radio is off. When the radio is turned off, a counter inside the
digital-support IC begins incrementing. That counter can be refreshed by the dual-core processor
through the SPI bus.
This is done so that the software has enough time to complete its tasks before the power is taken
away from the dual-core processor. If the counter is not refreshed by the time the count is complete,
the digital-support IC pin WD_OUT goes low, which shuts down the GCAP II voltage regulators.
During normal radio operation, WD_OUT should be high (V2 regulated voltage).
32 kHz Oscillator and CMOS Output
The 32 kHz oscillator circuitry uses a separate voltage supply pin (VDD3_XTL) than the other 3-V
portions of the digital-support IC. The oscillator circuitry is internal to the digital-support IC, and the
32.768 kHz crystal Y301 and additional load capacitors C308 and C309 are located next to the IC.
The output of the 32 kHz oscillator is an LI_CELL voltage (approximately 3 volts peak-to-peak),
32.768 kHz square wave on pin REF32_OUT. This clock goes to two destinations: the dual-core
processor CKIL pin (32 kHz test point) as a square wave and the GCAP II IC XTAL1 pin (C306) as a
sine wave.
Components C306 and C313 are used to filter the square wave into a sine wave before the signal
goes to the GCAP II IC.
13 MHz Reference Generation for GCAP II IC
The 13 MHz reference is required by the GCAP II IC for the CODEC time base and the SSI clock
generator module internal to the digital-support IC. A phase locked loop (PLL) is used to generate
the 13 MHz using the 16.8 MHz clock, which is provided to the digital-support IC REF_16_IN pin
(C307). An external RC loop filter network, consisting of R301, C301, and C302, is connected to the
PLL_LFT pin.
The 13 MHz reference output pin, REF_13_OUT, is conditioned by the RC network of R302 and
C303. The signal at REF_13_OUT is a 3-V peak-to-peak square wave, and the RC filter produces a
lower-level triangle wave that is suitable for the GCAP II IC.
The 13 MHz reference is disabled as the digital-support IC powers up. The 13 MHz reference is
enabled by the dual-core processor through the SPI bus, and, during normal radio operation, this
signal should be present.

2.5.2.3.2 ESD Protection Circuitry
NOTE: See Figure 12-13. NCN6186_ VOCON Universal Connector Circuit on page 12-19.
Several components on the VOCON board protect the circuitry from ESD. The side connector signal
lines have ESD protection components on them since they are exposed. These protection
components include:
• 5.6-V zeners VR205, VR206, VR220, and VR221 on the SB9600 lines, RS232 lines,
microphone lines, and option-select lines
• 12-V zeners VR201, VR203, and VR209 on the internal and external speaker and microphone
audio lines
• 13-V zener VR204 on the OPTB+ line
• Low-capacitance ESD suppressors C205, C206, C209 D203, VR220,VR221, and VR205 on
audio lines, USB datalines, and option-select lines
There were also several protection diodes on lines connected to the digital-support IC. These include
C224, C225, C226, C227, VR205, and VR206. ESD protection for the battery status line is provided
by a 5.6-V zener VR501.
2.5.2.3.3 Universal Connector Interface Circuitry
Some important components on the universal connector interface are two op-amps. The first opamp, U201, is used as a unity-gain buffer for the option-select line. Similarly, the other op-amp,
U202, is used as a comparator for the buffered option-select line. The comparator threshold is
determined by the voltage-divider network of R240 and R243.
Universal Connector and Option Selects
The universal connector is located on the back of the radio. It is the external port or interface to the
outside and is used for programming and interfacing to external accessories. The universal
connector connects to the VOCON board at connector J102 via a flex circuit that is routed inside the
external housing. Figure 2-9 shows the pinout for the universal side connector, and Table 2-10
shows the pin assignments. Connections to J102 on the VOCON board are shown in Figure 2-10.

Display Module
NOTE: The VOCON kit is only compatible with the 7285419E01 display module.
The 7285419E01 display module is an integral 112 by 32 pixel bit-mapped, liquid-crystal display
(LCD) module. The display module is connected to the VOCON board through flex connector J301.
It uses chip-on-film technology and is not field repairable.
The display module is controlled by the dual-core processor MCU core, which programs the display
through the serial peripheral interface (SPI) bus. The SPI bus programs the display through the
serial data line (pin 10), serial clock line (pin 7), chip select line (pin 3), and register select line (pin 6)
that is used to select the register to be programmed. The dual-core processor can reset the display
module through pin 2.
The display is supplied with 2.893V GCAP II regulated voltage (B700) to pins 11 and 14. Display
backlighting is controlled by the dual-core processor GPIO line BL_EN signal through components
R140 and Q101. The LEDs on the display module are powered by 5 V going through resistors R704,
R705, and Q700.

2.5.4

Controls and Control Top Flex
The housing assembly top controls include the On/Off/Volume switch (S1), a 16-position Channel
Select switch, and a programmable three-position (A,B,C) toggle switch (S2).
The side controls include three programmable pushbutton switches (top side button [SB1], side
button 1 [SB2], side button 2 [SB3]) and a Push-to-Talk (PTT) switch (SW2). These components are
connected through a flex circuit to the controller at J707.
UNSW_B+ is routed through switch S1 to provide the B+SENSE signal, which is used to activate the
SW_B+ and GCAP_B+ voltages that, in turn, power up the radio. Volume control is also provided by
S1, which contains a potentiometer biased between V2 regulated voltage and ground. The VOL
signal is a voltage level between V2 regulated voltage and ground, depending on the position of the
knob. The VOL signal is fed to buffer U506 pin 3, and then the output of the buffer is voltage-divided
down to 2.5 volts before the signal goes to the GCAP II IC AD5 pin. The dual-core processor reads
the GCAP II IC A/D value through the SPI bus, and from this reading, the dual-core processor DSP
adjusts the speaker volume.
Switch S2 is the three-position, programmable, toggle switch typically used for zone selection. The
switch can output the following voltages: 0 volts, half of the V2 regulated voltage, or V2 regulated
voltage (measurable at R523). The switch is connected to the GCAP II IC AD1 input pin through the
voltage divider network of R519 and R523. The dual-core processor reads the A/D value through the
SPI bus, and it uses that reading to determine the position of the toggle switch.

Theory of Operation: VOCON Board

Programmable side buttons SB1, SB2, and SB3 are active-low (activated when side button voltage
is 0V). When the side buttons are not pressed there are 2 V on the respective lines. S1 is a binarycoded switch. The output pins from U1, which are connected to GPIO pins on the dual-core
processor, provide a four-bit binary word (signals RTA0, RTA1, RTA2, and RTA3) to the MCU,
indicating to which of the 16 positions the rotary is set.

2.5.5

VOCON Audio Paths
This section describes the VOCON transmit and receive audio paths.

2.5.5.1 Transmit Audio Path
Refer to Figure 2-11. The internal microphone audio enters the VOCON board through pin 8 of the
M102 contact, and the internal microphone bias is set by circuitry that includes R531, R533, C519
and C521. The internal microphone signal is connected to the MICIN_NEG pin, which is the input
terminal on the GCAP II IC internal op-amp A3. The gain of the A3 op-amp is set by the values of
R540, R555, and the resistance of EEPOT U509 (digital potentiometer), which is programmed by
dual-core processor GPIO lines.
The external microphone audio enters the VOCON board through the remote connector J102, pin
10, and the external microphone bias is set by circuitry that includes R563, R565, C547, and C548.
The external microphone signal is connected to the AUX_MIC_NEG pin, which is an input terminal
on the GCAP II IC internal op-amp A5. The gain of the A5 op-amp is set by the values of R566,
R561, and the resistance of the EEPOT U509.
The dual-core processor, through the SPI bus, programs a multiplexer to select one of the
microphone signals. Then, the selected amplified microphone signal goes through a programmable
gain amplifier before it goes to the CODEC for A/D conversion. The resulting digital data is filtered
and sent to the DSP on the SAP CODEC_TX line from the GCAP II IC TX pin. After additional
filtering and processing, the DSP sends the data-out from the STDB pin to the RF interface
connector P201 pin 4 (TX_DATA), which is connected to the DAC U203 on the transceiver board.

Figure 2-11. VOCON Transmit Audio Path

2.5.5.2 Receive Audio Path
Refer to Figure 2-12. The receive audio data comes from the Abacus III IC U500 through the RF
interface connector P201 pin 12 (RX_DATA) to the dual-core processor SRDB pin. The DSP
decodes the data and sends it out through the CODEC_RX line to the GCAP II IC RX pin. The
CODEC filters and converts the digital data into an analog audio signal, which, in turn, is sent to a
programmable gain amplifier. The dual-core processor programs a multiplexer to route the audio
signal to the A4 amplifier, which has a fixed gain of 3.5 dB. The output of the A4 amplifier is pin
EXTOUT.
From the EXTOUT pin, the audio signal goes through the pre-amplifier U502 and then to the audio
power amplifier U503, which together provide approximately 30 dB of gain. The dual-core processor
selects whether the amplified audio is routed to the internal speaker or the external speaker.

Radio Power-Up/Power-Down Sequence
The radio power-up sequence begins when the user closes the radio On/Off switch on the control
top, placing 7.5 Vdc on the B+SENSE line. This voltage enables the pass element Q501 and Q502,
enabling SW_B+ and GCAP_B+.
When the GCAP II IC U501 detects a low-to-high voltage transition on GCAP_B+, it turns on and
enables voltage supplies VSW1, VSW2, V2 and Vref. As soon as these voltages come up, the
1.55 V regulator ramps up (only on the VOCON board), and the digital-support IC U301 drives the
WDI line high to enable VCC5 from regulator U505 and to maintain the GCAP II IC in the ON state. If
WDI remains low, the GCAP II IC turns off 50 ms after turning on.
The radio power-down sequence begins by opening the radio On/Off switch, which removes the
B+SENSE signal from the VOCON board. This does not immediately remove power because the
GCAP II IC has control of Q502 through Vref, and U301 through WDI maintains the GCAP II IC in an
active state. Both the MCU and digital-support IC monitor B+SENSE. After B+SENSE is removed,
the digital-support IC waits 125 ms. before releasing WDI to allow for software cleanup; however, the
software has the ability to prolong this time if it was necessary to complete its operations. When WDI
is released, the GCAP II IC shuts down its supplies and the rest of the radio through Q501.

Caution

6881094C12-A

To maintain the integrity of the RF PA, never heat it above 210°C while performing repair or
rework procedures. To prevent overheating the RF PA during rework, use a ChipMaster (R1319
or R1321) top-side pre-heat set point of 215°C and a Dragon (R1427) bottom-side pre-heat set
point of 204°C for 1 minute before and throughout top-side heat application, assuming that the
RF PA is removed from the applied heat 10 seconds after reflow occurs. (The RF PA
temperature does not reach the ChipMaster’s internal set point temperature). All other parts on
the transceiver board can be reworked with ChipMaster top-side heat alone.

Access the Test Mode
To enter the display radio test mode:
1. Turn the radio on.
2. Within 10 seconds of turning the radio on, press the one-dot side button five times in
succession.
The radio shows a series of displays that give information regarding various version numbers
and subscriber specific information. The displays are described in Table 4-2.
NOTE: When you turn the radio on normally, the radio performs a limited self-test. To allow the radio
to perform a full self-test, press and hold the top side button while turning the radio on. If the
self-test is successful, you hear a chirp. If the self-test is unsuccessful, you hear a single, lowfrequency tone and see an error code on the radio’s display. See Table 8-2 on page 8-2 for
the power-up error codes.

Chapter 5 Radio Alignment Procedures

This chapter describes radio alignment procedures for both the receiver and transmitter.

5.1

Radio Alignment Test Setup
A personal computer (PC) and tuner software (RVN4181) are required to align the radio. Refer to the
Customer Programming Software (CPS) Installation Guide (Motorola publication part number
6881095C44) for setup procedures for the software, and to the on-line help in the CPS for complete
field programming information. To perform the alignment procedures, the radio must be connected to
the PC and to a universal test set. The radio alignment test setup is shown in Figure 5-1.

Transmitter Alignments

5.5.1

Softpot

5-3

The alignment screens introduce the concept of the “softpot,” an analog SOFTware-controlled
POTentiometer used for adjusting all transceiver alignment controls.

!
Caution

DO NOT switch radios in the middle of any alignment
procedure. Always left-click the Close button on the screen to
return to the Main Menu screen before disconnecting the
radio. Improper exits from the alignment screens might leave
the radio in an improperly configured state and result in
seriously degraded radio or system performance.

Each alignment screen provides the ability to increase or decrease the softpot value by using a slider
or the spin buttons in the New Softpot Value box, or by entering the new value from the keyboard
directly into the box. The slider bar indicates the minimum and maximum values of the softpot, while
the Radio Softpot Value indicates the recommended value; see Figure 5-4.

Figure 5-4. Typical Softpot Screen
Adjusting the softpot value sends information to the radio to increase (or decrease) the voltage in the
corresponding circuit. For example, left-clicking the UP spin button in the New Softpot Value scroll
box on the Reference Oscillator screen instructs the radio’s microcomputer to increase the voltage
across a varactor in the reference oscillator, which increases the frequency.
In ALL cases, the softpot value is just a relative number corresponding to a digital-to-analog (D/A)
generated voltage in the radio.
Perform the following procedures in the sequence indicated.
NOTE: Some of the following screens may vary depending upon the radio under test and the version
of tuner software you are using. Refer to the software’s online help.

!

When keying the radio during a test, always transmit into a
dummy load.

Caution

5.5.2

Reference Oscillator Alignment
Adjustment of the reference oscillator is critical for proper radio operation. Improper adjustment will
result not only in poor operation, but also in a misaligned radio that will interfere with other users
operating on adjacent channels. For this reason, the reference oscillator should be checked every
time the radio is serviced, or once a year, whichever comes first. The frequency counter used for this
procedure must have a stability of 0.1 ppm (or better).

5. Left-click the Program All button on the screen to dekey the radio and save the tuned values.
6. Left-click the Close button on the screen to return to the Transmitter Alignments menu.

5.5.3

Transmit Power Alignment
This alignment procedure adjusts the transmit power of the radio and must be performed for two
different power levels (Low and High), at multiple frequencies for each power level, to allow for
proper alignment across the entire RF band. (The mid-power level is available to be tuned, but it
cannot be used.) The RF band is divided into frequency zones with a calibration point (value) in each
zone.
NOTES:
• The same softpot attenuation value will result in different radio output power levels at different
frequencies.
• All power measurements are to be made at the antenna port.
• Transmit Power alignment is required after replacing (or servicing) the transceiver board.

Transmit Deviation Balance Alignment
This alignment procedure balances the modulation contributions of the low- and high-frequency
portions of a baseband signal. Proper alignment is critical to the operation of signalling schemes that
have very low frequency components (for example, PL) and could result in distorted waveforms if
improperly adjusted.
This procedure needs to be performed at multiple frequencies to allow for proper alignment across
the entire RF band. The RF band is divided into frequency zones with a calibration point (value) in
each zone.
NOTE: This alignment is required after replacing (or servicing) the VOCON board or the transceiver
board.
To align transmit deviation balance:
1. Select the TX Deviation Balance alignment screen. The screen indicates the transmit
frequencies to be used. See Figure 5-8 on page 5-7.
2. Left-click the desired frequency field (starting with the highest frequency shown).
3. Left-click the PTT Toggle button on the screen to make the radio transmit. The screen
indicates whether the radio is transmitting.

Chapter 6 Encryption

This chapter describes the encryption capability of the SSE 5000 radio.

6.1

Load an Encryption Key
To load an encryption key:
1. Refer to the key-variable loader (KVL) manual for equipment connections and setup.
2. Attach the KVL to the radio. The display shows “KEYLOAD.” All other radio functions, except
for power down, backlight, and volume, are locked out.
3. Refer to the KVL manual for how to load the encryption keys into the radio.
4. When the key is loaded successfully, you will hear:
• On single-key radios—a short tone.
• On multikey radios—an alternating tone.

6.2

Multikey Feature
This feature allows the radio to be equipped with multiple encryption keys. The encryption keys can
be tied (strapped), on a one-per-channel basis. It can support up to three different encryption
algorithms simultaneously (DES, DES-XL and DES-OFB).

Chapter 7 Disassembly/Reassembly Procedures

This chapter provides detailed procedures for disassembling/reassembling SSE 5000 radios and
also includes preventive maintenance and handling precautions, which provide information vital to
the successful operation and maintenance of your radio.
When performing the disassembly/reassembly procedures, refer to the exploded view (Figure 7-1 on
page 7-3) and to the parts list (Table 7-1 on page 7-4). Items in parentheses ( ) throughout this
chapter refer to item numbers in the exploded view and its associated parts list.
This chapter also has procedures for removing and installing the SSE 5000 radio’s standard
accessories and changing the Volume and Channel Select knobs.

7.1

General Maintenance
In order to avoid operating outside the limits set by the FCC, we recommend that you align the
SSE 5000 radio’s reference oscillator every time the radio is taken apart, or once per year, whichever
comes first. Periodic visual inspection and cleaning is also recommended.

7.1.1

Inspection
Check that the external surfaces of the radio are clean, and that all external controls and switches
are functional. A detailed inspection of the interior electronic circuitry is not needed.

7.1.2

Cleaning
The following procedures describe the recommended cleaning agents and the methods to be used
when cleaning the external surfaces of the radio. External surfaces include the housing assembly
and battery case. These surfaces should be cleaned whenever a periodic visual inspection reveals
the presence of smudges, grease, and/or grime.
The only recommended agent for cleaning the external radio surfaces is a 0.5% solution of a mild
dishwashing detergent in water.

!
Caution

The effects of certain chemicals and their vapors can have harmful results
on certain plastics. Aerosol sprays, tuner cleaners, and other chemicals
should be avoided.

The detergent-water solution should be applied sparingly with a stiff, non-metallic, short-bristled
brush to work all loose dirt away from the radio. A soft, absorbent, lintless cloth or tissue should be
used to remove the solution and dry the radio. Make sure that no water remains entrapped near the
connectors, cracks, or crevices.

7-2

7.2

Disassembly/Reassembly Procedures: Handling Precautions

Handling Precautions
Complementary metal-oxide semiconductor (CMOS) devices, and other high-technology devices,
are used in this family of radios. While the attributes of these devices are many, their characteristics
make them susceptible to damage by electrostatic discharge (ESD) or high-voltage charges.
Damage can be latent, resulting in failures occurring weeks or months later. Therefore, special
precautions must be taken to prevent device damage during disassembly, troubleshooting, and
repair. Handling precautions are mandatory for this radio, and are especially important in lowhumidity conditions. DO NOT attempt to disassemble the radio without observing the following
handling precautions.
1. Eliminate static generators (plastics, Styrofoam, etc.) in the work area.
2. Remove nylon or double-knit polyester jackets, roll up long sleeves, and remove or tie back
loose-hanging neckties.
3. Store and transport all static-sensitive devices in ESD-protective containers.
4. Disconnect all power from the unit before ESD-sensitive components are removed or inserted
unless otherwise noted.
5. Use a static-safeguarded workstation, which can be accomplished through the use of an antistatic kit (Motorola part number 0180386A82). This kit includes a wrist strap, two ground
cords, a static-control table mat and a static-control floor mat.
• The SSE 5000 radio casting has one vent port that allows for pressure
equalization in the radio. Never poke this vent with any objects, such as
needles, tweezers, or screwdrivers.

!
Caution

• The pressure equalization vent is located on the chassis, just below the
battery contact. Never obstruct or cover the two slots with any object,
including a label. Ensure that no oily substances come in contact with this
vent.

If the radio battery contact area becomes wet, dry and clean the radio battery contacts before
attaching a battery to the radio. Otherwise, the water could short-circuit the radio.
If the radio has come into contact with water, shake the radio briskly so that any water that is trapped
inside the speaker grille and microphone port can be removed. Otherwise, the water will decrease
the audio quality of the radio.

!
Caution

November 11, 2004

To maintain the integrity of the RF PA, never heat it above
210°C while performing repair or rework procedures. To
prevent overheating the RF PA during rework, use a
ChipMaster (R1319 or R1321) top-side pre-heat set point of
215°C and a Dragon (R1427) bottom-side pre-heat set point
of 204°C for 1 minute before and throughout top-side heat
application, assuming that the RF PA is removed from the
applied heat 10 seconds after reflow occurs. (The RF PA
temperature does not reach the ChipMaster’s internal set
point temperature). All other parts on the transceiver board
can be reworked with ChipMaster top-side heat alone.

If the port seal needs to be replaced, it can be peeled off of the housing. All residual
adhesive on the housing must be removed before replacing the port seal.
2. Install the baseplate seal (9). Ensure that the baseplate seal is seated around the two
threaded radio contact bushings and the remainder of the seal is in the baseplate seal recess
of the housing.
NOTE: Inspect the baseplate seal for damage. If it is damaged, discard it and replace with
a new seal.
3. Install the latch spring (7) into the latch spring recess in the housing, with the convex form
facing the bottom of the radio.
4. Install the battery latch (4) into the battery latch recess in the housing, with the battery catch
facing the bottom of the radio.
5. Install the baseplate (2), taking care not to push the baseplate seal (9) into the housing. You
can verify this by looking into the bottom of housing to see if the seal has been pushed into
the housing.
6. Install the baseplate contact insulator (8).
7. Install the three power contacts (6).
8. Install the three radio power contact screws (5) using a ROTO-TORQ adjustable torque
screwdriver with a Phillips star bit (see Table 7-2 on page 7-10 for part numbers). Tighten all
three screws to 2.5 in-lbs.
9. If not done already, install the two self-sealing bolts (59) through the baseplate (2) on the
bottom of the radio. Using a ROTO-TORQ adjustable torque screwdriver with a T-10 TORX
bit (see Table 7-2 on page 7-10 for part numbers), tighten the two self-sealing bolts to 18 inlbs.
NOTE: Inspect the seals of the bolts before assembly. If the seals are damaged, discard
both the seals and the bolts and replace with new self-sealing bolts.
NOTE: If the Channel Select knob (32) or Volume knob (33) were removed prior to servicing the main
chassis, reinstall them. See Section 7.5.1.2: “Install the Channel Select Knob” on page 7-11
and Section 7.5.2.2: “Install the Volume Knob” on page 7-12.

Chapter 8 Troubleshooting

The purpose of this chapter is to aid in troubleshooting problems with the SSE 5000 radio. It is
intended to be detailed enough to localize the malfunctioning circuit and isolate the defective
component.

8.1

Voltage Measurement and Signal Tracing
It is always a good idea to check the battery voltage under load. This can be done by checking the
OPT_B+_VPP pin at the accessory connector (pin 8). The battery voltage should remain at or above
7.0 Vdc. If the battery voltage is less than 7.0 Vdc, then it should be recharged or replaced as
necessary prior to analyzing the radio.
In most instances, the problem circuit may be identified using a multimeter, an RF millivoltmeter,
oscilloscope (preferably with 100 MHz bandwidth or more), and a spectrum analyzer.

!
Caution

8.2

When checking a transistor or module, either in or out of
circuit, do not use an ohmmeter having more than 1.5 Vdc
appearing across test leads or use an ohms scale of less than
x100.

Standard Bias Table
Table 8-1 outlines some standard supply voltages and system clocks which should be present under
normal operation. These should be checked as a first step to any troubleshooting procedure.

Troubleshooting: Power-Up Error Codes

Power-Up Error Codes
When the radio is turned on (power-up), the radio performs self-tests to determine if its basic
electronics and software are in working order. When you turn the radio on normally, the radio
performs a limited self-test. This allows the radio to achieve full power within two seconds. To allow
the radio to perform a full self-test (which extends the time required to achieve full power), press and
hold the top side button while turning the radio on. If the self-test is successful, you hear a chirp. If
the self-test is unsuccessful, you hear a single, low-frequency tone and see an error code on the
radio’s display. The radio should be sent to the depot if cycling power and reprogramming the code
plug do not solve the problem. The presence of an error should prompt the user that a problem exists
and that a service technician may need to be contacted.
Self-test errors are classified as either fatal or non-fatal. Fatal errors will inhibit user operation; nonfatal errors will not. Use Table 8-2 to aid in understanding particular power-up error code displays.

Chapter 9 Troubleshooting Charts

This section contains detailed troubleshooting flowcharts. These charts should be used as a guide in
determining the problem areas. They are not a substitute for knowledge of circuit operation and
astute troubleshooting techniques. It is advisable to refer to the related detailed circuit descriptions in
the theory of operation sections prior to troubleshooting a radio.

9.1

List of Troubleshooting Charts
Most troubleshooting charts (see Table 9-1) end up by pointing to an IC to replace. It is not always
noted, but it is good practice to verify supplies and grounds to the affected IC and to trace
continuity to the malfunctioning signal and related circuitry before replacing any IC. For
instance, if a clock signal is not available at a destination, continuity from the source IC should be
checked before replacing the source IC.

DC Supply Failure—Page 1
NOTE: Since the failure of a critical voltage supply might cause the radio to automatically power
down, supply voltages should first be probed with a multimeter. If all the board voltages
are absent, then the voltage test point should be retested using a rising-edge-triggered
oscilloscope. If the voltage is still absent, then another voltage should be tested using the
oscilloscope. If that voltage is present, then the original voltage supply in question is
defective and requires investigation of associated circuitry.

Synopsis
This failure relates only to secure-equipped
radios and indicates a power-up self-test failure
for the secure module. More specifically this
failure indicates a failure in communications
between the DSP and secure module. The
secure module is not considered field repairable
so troubleshooting is limited to verifying a
problem with the module and replacing.
Typical failure modes would be:
1) Open between secure module and VOCON
board at J701.
2) Failure of the SSI bus that the DSP uses to
communicate with the secure module.
3) Failure to get proper supplies and grounds
to J701.
