3.4.4 RADIO-WIDE SMARTNET/SMARTZONE

SCREEN

The radio-wide SMARTNET/SmartZone screen

is shown above, and it is used to program these

parameters:

Full Spectrum CC Scan

In a SmartZone system, if all potential control

channel frequencies have been searched, the radio

enters a channel-by-channel search across the full

spectrum that the radio covers. The timer sets the time

it performs this scan before it checks the expected

frequencies again. After it checks these frequencies, it

returns to full spectrum scanning. This cycle repeats

until a control channel is found.

On-Off - Enables or disables full spectrum scan.

Timer - Sets the time that full spectrum scanning

occurs as just described.

Hot DTMF

Enable/Disable - When enabled, allows the user to

send DTMF tones while transmitting. When

disabled, pressing numeric keys (0-9, *, #) while

transmitting has no affect. This option is not func-

tional with SecureNet operation.

Display Options

See description in Section 3.4.3.

Scan Talkback

When a message is received when scanning, this

determines if the response always occurs on the

selected talk group or the talk group of the call (when

not the same).

Voice On Control

With SmartZone operation, some remote sites are

designated Voice On Control sites. In these sites, if all

available traffic channels are occupied, control chan-

nels become traffic channels when additional traffic

channels are requested. The Voice On Control parame-

ters determine how the radio reacts to various situa-

tions that may occur. For example, when a conversa-

tion is complete, the radio may look for a control

channel that has become a traffic channel.

Enable/Disable - Determines if the voice on control

parameters are active.

Site Lock Time - This is the amount of time a radio

remains on the Voice On Control site before looking

for another site.

Activation Time - This is the amount of time the

radio waits when the control channel comes back

from Voice On Control before it transmits any pend-

ing ISWs. This prevents all radios on a Voice On

Control site from submitting ISWs at the same time.

Pending Emergency Time - This is the amount of

time the radio waits to submit an Emergency ISW

after the control channel returns from the Voice On

Control mode.

TRANSCEIVER PROGRAMMING

3-12 September 2001

Part No. 001-5100-001

Adjustable Parameters

Busy Override Delay - With SmartZone operation,

this is the amount of time a user must press the PTT

switch to override a SmartZone busy that occurs

because some member of the talk group is present at

a site where there are no traffic channels available.

Affiliate Hold Off - With SmartZone operation, this

is the delay time that occurs after acquiring the con-

trol channel before it sends an affiliation ISW. This

prevents all radios on the system from sending affil-

iation ISWs at the same time.

Failsoft Inactivity - Programs failsoft operation (see

Section 2.7.11). If the radio remains inactive (no

receive or transmit activity on channel) while operat-

ing in the failsoft mode for the programmed time, the

radio momentarily leaves the failsoft mode and

attempts to find a control channel. If “0” is pro-

grammed, the radio does not leave the failsoft mode.

3.4.5 RADIO-WIDE PORTABLE OPTIONS

SCREEN

The radio-wide Portable Options screen is shown

above, and it is used to program these parameters:

Standby Chirp - If this box is checked, a chirp sounds

periodically in the standby mode while a low battery

condition is being detected.

Tx Chirp - If this box is checked, a chirp sounds each

time the PTT switch is pressed while a low battery

condition is being detected.

LED Indicator - If this box is checked, the LED on

the top panel indicates a low battery condition (green

in standby, flashing red in transmit).

3.5 PROGRAMMING CONVENTIONAL

programmed. Therefore, first program the channels as

described in Sections 3.5.5, 3.5.6, and 3.5.7.

Conventional System Scan List Screen

To modify a list, click and the

screen which follows is displayed. Select the desired

scan list in the box on the top and then select the zone

and the channels from that zone to be included. Repeat

for each zone. Do this for each list programmed. The

button deletes the selected channel(s)

from the scan list.

The following parameters are programmed in the

preceding Conventional System Scan List Screen.

Keypad Editing

This selects if the user is allowed to edit the scan

list. This requires the Scan Edit option switch as

described in Section 2.6.12. User editing can be

enabled or disabled on each scan list.

Scan Mode

This function selects the channel on which trans-

missions occur when the PTT switch is pressed while

scanning. In addition, it selects if priority sampling is

used and also the type of priority channel (see

“Priority Channel” description which follows). The

following modes are available:

TRANSCEIVER PROGRAMMING

3-14 September 2001

Part No. 001-5100-001

No Priority - Priority sampling does not occur (all

channels are scanned in sequence). The radio trans-

mits on the selected channel.

Priority/Tx Priority - Priority sampling occurs

and the priority channel is the one programmed in

the selected scan list. The radio transmits on the

priority channel.

Priority/Tx Selected - Priority sampling occurs

and the priority channel is the one programmed in

the selected scan list. The radio transmits on the

selected channel.

Priority on Sel Chan - The priority channel is

always the selected channel (even if the scan list is

programmed with a priority channel). The radio

transmits on the selected channel.

Talkba c k - No priority sampling occurs. The radio

transmits on the channel of a call while scanning is

halted. Then when scanning resumes, it transmits

on the selected channel.

Scan Timers

Scan Hold Time - Sets the delay that occurs before

scanning resumes after a signal is no longer

received (see Section 2.5.4).

Lookback Time A - This time determines how

often the priority channel is checked for activity.

Times of 0.25-4.00 seconds in 0.25-second steps

can be programmed.

Lookback Time B - This time determines how

often the priority channel is checked once an incor-

rect Call Guard (CTCSS/DCS) or NAC code is

detected. Since it takes much longer to detect an

incorrect Call Guard signal than a carrier, this time

should be relatively long to prevent the interrup-

tions from making a message difficult to under-

stand. Times of 0.5-8.0 seconds can be

programmed in 0.5-second steps.

Priority Channel Selection

The Scan Mode parameter just described selects

if priority channel sampling is enabled on the selected

scan list. It also selects the type or priority channel

(either fixed or selected) if applicable.

If the “Priority/Tx Priority” or “Priority/Tx

Selected” mode is programmed, fixed priority

sampling is selected. The priority channel must then

be chosen for the scan list. To do this, click the

button in the Modify Scan List screen

and then select the desired zone/channel. If any of the

other modes is selected, the priority channel does not

need to be chosen. Refer to Section 2.6.13 for more

information on priority sampling.

quencies, a receive frequency 45 MHz above the

transmit frequency is automatically entered.

New Entry Button - Click this button to display the

dialog box used to add another control channel.

Trunking Call List Screen

This screen is shown above, and it allows the list

of IDs used for private calls to be programmed. A

maximum of 16 IDs can be programmed (see Section

2.7.4).

To edit this list, click the Trunking Call List tab

and then the “Modify List” button on the right side.

This following information is then programmed in the

dialog box that is displayed:

Entry Number - This box selects the entry to be

edited. The scroll bars to the right of this box select

the desired entry. A phone list can contain up to 16

entries. Selecting a new entry number automatically

validates and stores the current entry. If the current

entry contains an invalid field, the entry number does

not change and the invalid field is highlighted.

Entry Alias - Up to ten characters can be entered to

identify the user being called. This identification is

displayed when the mobile to be called is selected by

the user from the list. Only uppercase letters can be

entered, so lowercase letters are automatically con-

verted to uppercase by the program.

Call ID - This is the ID of the radio being called.

Valid entries are 1-49152. A “0” is detected as no

entry.

Close Button - Verifies the current entry, stores it,

and then closes the dialog box. If the current entry

contains an invalid field, the dialog box does not

close and the invalid field is highlighted.

Priority Monitor Scan Screen

This screen is shown above, and it programs up to

three Priority Monitor scan lists that are allowed. Each

scan list can contain up to 15 channels plus a priority

channel (see Section 2.7.12). These channels must be

from the same SMARTNET/SmartZone system. Chan-

nels set up for other systems are not allowed.

To edit a list, click the Priority Monitor Scan tab

and then click the “Modify List” button on the right

side. A screen similar to the top screen shown above is

then displayed to select the channels to be included in

that scan list. Select channels as follows:

1. Select the scan list to be edited using the scroll bars

next to the “Scan List To Modify” box.

2. Select the first zone with channels to be included

and select the desired channels. Repeat for the other

applicable.

Status Aliasing Screen

This screen is shown above, and it programs the

alias for each of up to eight status conditions that can

be sent. The meaning of each status number is defined

by the system manager. Refer to Section 2.7.9 for

more information.

To edit this list, click the Status Aliasing tab and

then the “Modify List” button on the right side. The

following information is then programmed in the

dialog box that is displayed:

Status Number - The scroll bars to the right of this

box select the status number that is to be edited.

Status Alias - Programs up to 10 characters that iden-

tify the status. This identification is displayed when

the user selects a status condition.

Other Band Trunking Screen

The Other Band Trunking screen follows, and it

is displayed only when programming channels in the

VHF and UHF frequency bands. It is used to define

the relationship between the transmit and receive

channel frequencies in these bands. With 800 MHz

systems, this is not required because the difference

between the transmit and receive frequency is always

45 MHz.

Other Band Trunking Screen

This screen organizes the available frequency

band into three sub-bands, called splits. Each split is

defined by a start frequency, stop frequency, and

channel spacing as follows. Frequencies outside the

defined split cannot be accessed by the radio. These

frequency splits must be defined the same way they

are defined for the trunking controller.

Tx and Rx Spacing - Spacing in kHz between each

potential transmit and receive frequency.

Tx and Rx Start Frequency - Start in MHz of the band

split for transmit and receive frequencies.

Tx and Rx Stop Frequency - Stop in MHz of the band

split for transmit and receive frequencies.

3.6.8 SETTING UP SMARTNET/SMARTZONE

CHANNELS

The SMARTNET/SmartZone Channel screen

shown in Figure 3-5 is displayed when the

SMARTNET or SmartZone channel type is selected.

TRANSCEIVER PROGRAMMING

3-28 September 2001

Part No. 001-5100-001

Transmit - Not programmable because the transmit

frequency is dynamically assigned over the

air (“Trunked” is always displayed).

Receive - Dynamically assigned like the preceding

transmit frequency.

Enable This Channel - Not used because SMART-

NET/SmartZone channels are always

enabled if set up. To disable a channel so

that it is not selectable, choose the conven-

tional type and do not check this box.

Copy Parameters From Channel - If another channel

is selected in the box, the parameters from

that channel are copied to the new channel.

Channel Type

Channel Type Box - Selects the specific system from

which the channel is selected. All programmed

systems are displayed by number and type (conven-

tional, SMARTNET, SmartZone). When a different

channel type is selected, the screen for that type of

channel is automatically displayed.

Other Screen Parameters

System Specific Information - With SMARTNET/

SmartZone systems, indicates the system ID

programmed on the system General screen (see

Section 3.6.2).

Talk Group - Selects the talk group selected by that

channel. Talk groups are programmed in the Talk

Group screen described in Section 3.6.5.

Announcement Group - Selects one of up to three

announcement groups selected by the channel. Refer

to “Announcement Group Screen” in Section 3.6.7

for more information.

Emergency Group - Selects the talk group used for

emergency calls.

Talk Permit Tone - When enabled, a short tone

sounds after a request for a group call has been

approved by the main controller. This indicates that

speaking can begin. When disabled, no audio feed-

back is used to indicate when speaking can begin.

System Scan - Selects the Priority Monitor Scan list

selected by the channel (see “Priority Monitor Scan

Screen” description in Section 3.6.7). If “No Scan

List” is programmed, scanning is not selectable on

that channel.

Auto Scan - When enabled and a channel is selected,

the radio automatically begins scanning the scan list

associated with that channel. When disabled, scan-

ning can only be started manually by the Scan option

switch.

3.7 PASSWORD OPERATION

3.7.1 GENERAL

The 50xx portable radio can be programmed with

a Power-Up and Programming password. If the Power-

Up password is enabled, it must be entered each time

power is turned on to make the radio operational. This

prevents unauthorized use. The Programming pass-

word must be entered to access the keypad program-

ming feature of the radio. This prevents unauthorized

reprogramming of the transceiver. Currently, the 50xx

portable is the only transceiver that is programmed

with the PCTrunk software that utilizes password

access. More information on these two passwords

follows.

3.7.2 POWER-UP PASSWORD

The Power-Up password function is enabled on

the Radio-Wide General screen described in Section

3.4.2. This password must then be entered each time

transceiver power is turned on. In addition, since the

radio resets after downloading or uploading data, it

must be entered after performing those functions (see

Sections 3.3.3 and 3.3.4). When entering the pass-

word using the radio keypad, enter the eight password

digits and then press the ENT key. If an error is made,

press the CLR key to start over.

To enable the power-up password function on the

programmer screen, the Power-Up password must be

entered. This prevents the radio from being

programmed with an unknown password which would

make it inoperable. The password is a series of eight

numbers, and it is programmed by clicking the

“Change Password” button on the Radio-Wide

General screen. The default password is eight zeros

(00000000), and it may need to be entered as the “old”

password if applicable. The password can also be

TRANSCEIVER PROGRAMMING

3-29 September 2001

Part No. 001-5100-001

changed using the radio keypad when the keypad is

locked by entering the old password and then pressing

the # key. Refer to Section 2.4.3 for more information.

If the Power-Up password has been enabled in the

radio connected to the programmer, the Programming

password described in the next section must then be

entered before a data can be downloaded or uploaded.

This prevents an unauthorized person from reading

radio data or changing radio programming.

If the password is forgotten, it can be overridden

by pressing the lower button on the side 8 times. This

unlocks the radio and reverts to the default password

of “00000000”. However, it also erases all channel

frequencies, trunked group IDs, and encryption infor-

mation. Therefore, the radio must be reprogrammed

after this is done to make it operational again.

3.7.3 PROGRAMMING PASSWORD

The Programming password must be entered to

enable the Keypad Programming mode described in

Section 2.9. This prevents an unauthorized person

from changing the radio programming. As described

in the preceding section, the Programming password

must also be entered when downloading or uploading

data from a radio that has the Power-Up password

function enabled.

CIRCUIT DESCRIPTION

SECTION 4 CIRCUIT DESCRIPTION

4.1 GENERAL OVERVIEW

4.1.1 INTRODUCTION

The E.F Johnson 5100 series digital portable

radio is a microcontroller-based radio that uses a

Digital Signal Processor (DSP) to provide the

following modes of operation:

Narrowband Analog - FM modulation with a

maximum deviation of 2.5 kHz. This mode is usually

used in systems where the channel spacing is 12.5

kHz. Call Guard (CTCSS or DCS) subaudible squelch

signaling can be used in this mode.

Wideband Analog - FM modulation with a maximum

deviation of 5 kHz. This mode is usually used in

systems where the channel spacing is 25 kHz or 30

kHz. Call Guard (CTCSS or DCS) subaudible squelch

signaling can be used in this mode.

Project 25 Digital - The voice is digitized, error

corrected, optionally encrypted and transmitted using

C4FM modulation according to the Project 25 stan-

dard. This mode can be used in channel spacings of

12.5 kHz.

The DSP processes the received signals and

generates the appropriate output signals. The micro-

controller controls the hardware and provides an inter-

face between hardware and DSP.

PC Boards

This radio contains the following PC boards:

•RF Board

•Digital Board

•Keypad Board

•Four flex circuits that provide interconnection and

support for the volume, on/off, and LED controls.

•Encryption board (optional)

The Keypad Board provides the input/output

interface for the user. It accepts input from the keypad

and the various control knobs and sends the appro-

priate signals to the DSP on the Digital Board and to

the RF Board for proper configuration. It provides the

dual display information to inform the user of the

status of the radio. It also performs all RS-232 commu-

nications between the radio and remote computer

stations for the purposes of radio programming, tuning,

encryption key loading and software downloading.

4.1.2 ANALOG MODE

Receive Mode

The signal is routed from the antenna connector

to the RF Board where it is filtered, amplified, and

mixed with the first local oscillator frequency gener-

ated by the synthesizer. The resulting IF signal is also

filtered and amplified and sent to the ABACUS chip.

The signal is then mixed with the second local

oscillator frequency to create a second IF signal of 450

kHz. The second IF signal is then sampled at 14.4

Msps and downconverted to baseband. The baseband

signal is then decimated to a lower sample rate that is

selectable at 20 kHz. This signal is then routed via a

serial interface using a differential current output to

the ADSIC chip on the Digital Board.

On the Digital Board the ADSIC digitally filters

the input signal, performs frequency discrimination to

obtain the message signal and then routes the message

signal to the DSP. The DSP first performs a carrier-

detection squelch function on the radio. If a signal is

determined to be present, the audio portion of the

signal is resampled to an 8 kHz rate and then filtered

appropriately. The filtered signal is then routed back to

a D/A in the ADSIC to produce an analog signal for

output to the audio power amplifier (PA) and then the

speaker. Any detected signaling information is

decoded and the resulting information is sent to the

microcontroller.

CIRCUIT DESCRIPTION

4-2 September 2001

Part No. 001-5100-001

Transmit Mode

The signal from the microphone is amplified by

the audio PA and is then routed to the ADSIC chip

where it is first digitized at a 16 ksps rate and then sent

to the DSP. The DSP performs the required filtering,

adds the desired signaling, converts the sample rate to

48 ksps and then sends the resulting signal back to a

D/A in the ADSIC to produce the analog modulation

signal for the VCO. The modulated VCO signal is then

sent to the RF PA for transmission.

4.1.3 PROJECT 25 DIGITAL MODE

Introduction

In Project 25 Digital Mode, the carrier is modu-

lated with 4 discrete deviation levels. These levels are

± 600 Hz and ± 1800 Hz. Digitized voice is created

using an IMBE™ vocoder.

Receive Mode

The signal is processed in the same way as an

analog mode transmission until after the squelch func-

tion is performed. If a signal is detected to be present,

the DSP resamples the signal from 20 kHz to 24 kHz.

This is done so that the sample rate is an integer

multiple (5x) of the data rate of the digital modulation

which is 4800 symbols/sec (9600 bits/sec).

The resampled signal is then processed by a

demodulator routine to extract the digital information.

The resulting bit stream (9600 bps) is sent to a routine

that performs unframing, error-correction, and voice

decoding. The result of these operations is a recon-

structed voice signal sampled at 8 kHz. The sampled

voice signal is sent to a D/A in the ADSIC to produce

an analog signal for output to the audio power ampli-

fier and speaker.

Transmit Mode

The microphone signal is processed as in the

analog mode until it reaches the DSP. At this point the

audio signal is processed by a voice encoding routine

to digitize the information. The resulting samples are

then converted to a bit stream that is placed into the

proper framing structure and error protected. The

resulting bit stream has a bit rate of 9600 Hz.

This bit stream in then encoded, two bits at a

time, into a digital level corresponding to one of the

four allowable frequency deviations. This produces

16-bit symbols with a rate of 4800 Hz. The symbols

are resampled to a rate of 48 kHz and filtered to

comply with channel bandwidth requirements. The

filtered signal is then sent to a D/A in the ADSIC to

produce the analog modulation signal for the VCO.

The modulated VCO signal is then mixed up to the

final transmit frequency and then sent to the RF PA for

transmission.

4.1.4 RF BOARD

NOTE: The RF Board is not field serviceable. It must

be replaced as a unit with a new board.

The receiver front end consists of a preselector,

RF amplifier, second preselector, and mixer. Both

preselectors on the VHF and UHF board are varactor-

tuned, two-pole filters controlled by the microcon-

troller unit through the D/A IC. The 800 MHz board

uses stripline technology for the preselector. The RF

amplifier is a dual-gate gallium-arsenide IC. The

mixer is a double-balanced, transformer-coupled

active mixer. Injection is provided by the VCO

through an injection filter. See Table 4-1 for local

oscillator (LO) and first IF information.

The frequency generation function is performed

by three ICs and associated circuitry. The reference

oscillator provides a frequency standard to the synthe-

sizer/prescaler IC which controls the VCO IC. The

VCO IC actually generates the first LO and transmit

injection signals and buffers them to the required

power level. The synthesizer/prescaler circuit module

incorporates frequency division and comparison

circuitry to keep the VCO signals stable. The synthe-

sizer/prescaler IC is controlled by the microcontroller

through a serial bus. Most of the synthesizer circuitry

is enclosed in rigid metal on the RF Board to reduce

microphonic effects.

The receiver back end consists of a two-pole

crystal filter, IF amplifier, a second two-pole crystal

filter, and the ABACUS digital back-end IC. The two

pole filters are wide enough to accommodate 5 kHz

modulation. Final IF filtering is done digitally in the

ADSIC.

The ABACUS digital back-end chip consists of

an amplifier, second mixer, IF analog-to-digital

converter, a baseband down-converter, and a 2.4 MHz

synthesis circuit to provide a clock to the ADSIC on

the Digital Board. The second LO is generated by

discrete components external to the ABACUS. The

output of the ABACUS is a digital bit stream that is

current driven on a differential pair to reduce noise

generation.

The transmitter consists of an RF power amplifier

IC that amplifies an injection signal from the VCO.

Transmit power is controlled by two custom ICs that

monitor the output of a directional coupler and adjust

the power amplifier control voltages correspondingly.

The signal passes through a Rx/Tx switch that uses

PIN diodes to automatically provide an appropriate

interface to transmit or receive signals.

4.1.5 DIGITAL BOARD

The Digital Board contains the ADSIC, DSP

(TMS320C50), static RAM, FLASH memory, and a

programmable logic IC. The RF Board and Keypad/

Display Board are connected to the Digital Board. The

ADSIC performs the Frequency Discrimination and

receiver filtering functions. It also performs analog-to-

digital (A/D) and digital-to-analog (D/A) conversion.

The DSP performs demodulation and modulation,

voice encoding and decoding, audio filtering, and

squelch signaling. The software for the radio is stored

in FLASH memory that is loaded in to static RAM at

turn-on. The programmable logic IC controls which

device (Flash, SRAM, or UART) is connected to the

DSP address and data bus.

4.1.6 KEYPAD/DISPLAY BOARD

The Keypad Board contains the microcontroller

(HC08), audio circuits, front LCD display assembly,

display driver, and 5V analog and 5V digital regula-

tors. All interfaces to the side connector and the

switches are on this board. The microcontroller deter-

mines transmit/receive frequencies, power levels, and

display content. It communicates with the DSP via a

serial interface.

4.2 POWER SUPPLY

4.2.1 GENERAL

The radio is typically powered by a battery which

is fastened at the back of the radio. The electrical

contact between the battery and the radio occurs on

probes located on the Digital board (see Figure 4-1).

However the positive battery voltage (UNSWB+) is

directly routed through a small flex circuit (Power

Flex) to contacts located on the bottom of the RF

Board.

The UNSWB+ signal is then routed to the RF

power amplifier module and ALC IC on the RF Board.

It also passes through a fuse and is then routed to the

Digital Board.

The UNSWB+ signal passes through the Digital

Board without being used and is transferred to the

Keypad Board. On the keypad board, the UNSWB+

signal is routed as follows:

•Input of the 5V digital regulator

•Electronic switch which controls the input of the 5V

analog regulator and the “switched RF B+”

•“On/off switch” located on the top of the radio

•Low voltage detector

•Audio amplifier power FET

4.2.2 POWER ON OPERATION

When the user turns the radio on using the top

panel “on/off switch”, the following sequence of

events occur:

1. Power is applied to the shutdown pin of the 5V

digital regulator.

2. The 5-volt digital supply is created.

3. The appearance of the 5V digital supply turns on the

electronic switch which applies the battery voltage

to the “Switched RF B+” line and to the input of the

5V analog regulator.

4. The 5-volt analog supply is created.

5. If the battery voltage is high enough, the low voltage

detector output goes high.

6. The controller sets the control line to the shutdown

pin of the DC/DC converter to a high level.

7. The controller sets the radio in an operational mode.

4.2.3 POWER OFF OPERATION

When the user turns the radio off using the top

panel “on/off switch”, the following sequence of

events occur:

1. The “on/off switch” opens.

2. Power is removed from the shutdown pin of the 5V

DC/DC converter.

3. The controller detects that the power is off through

the pin connected to Switched B+.

4. The controller performs all required save

operations.

5. The controller resets the control line to the shut-

down pin of the DC/DC converter.

6. The 5-volt Digital source disappears.

7. The electronic switch opens.

8. The switched RF B+ and 5V analog sources

disappear.

4.2.4 LOW VOLTAGE DETECT

Low battery voltage is detected by a comparator

chip. When a low voltage condition is detected (less

than 6.3V), the following actions occur:

1. The low voltage detector output goes low which

alerts the controller.

2. The controller prevents any action which could have

a damaging effect (like writing in flash memory).

3. The controller releases its control of the shutdown

pin of the DC/DC converter.

4. The transmitter switches to the low power mode.

5. When the voltage gets really low, the 5 volt DC/DC

converter automatically shuts down.

6. The 5-volt analog and switched RF B+ sources turn

off.

4.3 RF BOARD CIRCUIT DESCRIPTION

4.3.1 FREQUENCY GENERATION UNIT

The Frequency Generation Unit (FGU) consists

of these three major sections: (1) high stability refer-

ence oscillator, (2) fractional-N synthesizer, and (3)

VCO buffer. A 5-volt regulator supplies power to the

FGU. The regulator output voltage is filtered and then

distributed to the transmit and receive VCOs and the

VCO buffer IC. The mixer LO injection signal and

transmit frequency are generated by the receive VCO

and transmit VCO, respectively. The receive VCO

uses an external active device, and the transmit VCO

active device is a transistor inside the VCO buffer.

The receive VCO is a Colpitts-type oscillator.

The receive VCO signal is received by the VCO buffer

where it is amplified by a buffer inside the IC. The

amplified signal is routed through a low-pass filter and

injected as the first LO signal into the mixer. In the

VCO buffer, the receive VCO signal is also routed to

an internal prescaler buffer. The buffered output is

applied to a low-pass filter. After filtering, the signal is

routed to a prescaler divider in the synthesizer.

The divide ratios for the prescaler circuits are

determined from information stored in an EEPROM.

The microprocessor extracts data for the division ratio

as determined by the position of the channel-select

switch and routes the signal to a comparator in the

synthesizer. A 16.8 MHz reference oscillator applies

the 16.8 MHz signal to the synthesizer. The oscillator

signal is divided into one of three pre-determined

frequencies. A time-based algorithm is used to

generate the fractional-N ratio.

If the two frequencies in the synthesizer’s

comparator differ, an error voltage is produced. The

phase detector error voltage is applied to the loop

filter. The filtered voltage alters the VCO frequency

until the correct frequency is synthesized.

In the transmit mode, the modulation of the

carrier is achieved by using a two-port modulation

technique. The modulation for low frequency tones,

such as CTCSS and DCS, is achieved by injecting the

tones into the A/D section of the fractional-N divider,

generating the required deviation. Modulation of the

high frequency audio signals is achieved by modu-

lating the varactor through a frequency compensation

network.

RF BOARD

CIRCUIT DESCRIPTION

4-6 September 2001

Part No. 001-5100-001

The transmit VCO signal is amplified by an inter-

nal buffer, routed through a low-pass filter, and then

sent to the transmit power amplifier module. The refer-

ence oscillator supplies a 16.8 MHz clock to the synthe-

sizer where it is divided down to a 2.1 MHz clock. This

divided down clock is fed to the ABACUS IC.

4.3.2 ANTENNA SWITCH

A pair of diodes is used to electronically steer the

RF signal between the receiver and transmitter. In the

transmit mode, RF is routed through a transmit switch-

ing diode and sent to the antenna. In receive mode, RF

is received from the antenna, routed through a receive

switching diode and applied to the RF amplifier.

4.3.3 RECEIVER FRONT END

The RF signal from the antenna is sent through a

bandpass filter. The bandpass filter is electronically

tuned by the microcontroller via the D/A IC by

applying a control voltage to the varactor diodes in the

filter. The D/A output range is extended through the

use of a current mirror. Wideband operation of the

filter is achieved by retuning the bandpass filter across

the band.

The output of the bandpass filter is applied to a

wideband amplifier. After being amplified by the RF

amplifier, the RF signal is further filtered by a second

broadband, fixed tuned, bandpass filter to improve

spurious rejection.

The filtered RF signal is routed via a broadband

50 Ω transformer to the input of a broadband mixer/

buffer. The mixer uses GaAs FETs in a double-

balanced Gilbert Cell configuration. The RF signal is

mixed with a first LO signal of about –10 dBm

supplied by the FGU. Mixing of the RF and the first

LO results in an output signal which is the first IF

frequency according to Figure 4-1. The first IF signal

output is routed through a transformer and impedance

matching components and is then applied to a two-

pole crystal filter. The 2-pole crystal filter removes

unwanted mixer products.

4.3.4 RECEIVER BACK END

The output of the crystal filter is matched to the

input of the IF buffer amplifier transistor. The output

of the IF amplifier is applied to a second crystal filter

through a matching circuit. This filter supplies further

attenuation at the IF sidebands to increase radio

selectivity.

In the ABACUS IC the first IF frequency is

amplified and then downconverted to 450 KHz, the

second IF frequency. At this point, the analog signal is

converted into two digital bit streams via a sigma-delta

A/D converter. The bit streams are then digitally

filtered and mixed down to baseband and filtered

again. The differential output data stream is then sent

to the ADSIC on the Digital Board where it is

processed to produce the recovered audio.

The ABACUS IC is electronically program-

mable, and the amount of filtering, which is dependent

on the radio channel spacing and signal type, is

controlled by the microcontroller. Additional filtering,

which used to be provided externally by a conven-

tional ceramic filter, is replaced by internal digital

filters in the ABACUS IC. The ABACUS IC contains

a feedback AGC circuit to expand the dynamic range

of the sigma-delta converter. The differential output

data contains the quadrature (I and Q) information in

16-bit words, the AGC information in a 9-bit word,

imbedded word sync information and fill bits depen-

dent on sampling speed. A fractional-N synthesizer is

also incorporated on the ABACUS IC for 2nd LO

generation.

The 2nd LO/VCO is a Colpitts oscillator. The

VCO has a varactor diode to adjust the VCO

frequency. The control signal for the varactor is

derived from a loop filter.

4.3.5 TRANSMITTER

The transmitter consists of three major sections:

Harmonic Filter, RF Power Amplifier, and the ALC

(Automatic Level Control) circuit.

The RF signal from the PA module is routed

through a coupler, then through the harmonic filter,

then to the antenna switch. The RF power amplifier

module is a wide-band multi-stage amplifier. The

nominal input and output impedance of the power

amplifier is 50 Ω. The DC bias for the RF power

amplifier is controlled by a switching transistor. The

microcontroller uses the D/A IC to produce a ready

RF BOARD (CONT’D)

CIRCUIT DESCRIPTION

4-7 September 2001

signal for the transmit ALC IC. The synthesizer sends

a LOC signal to the transmit ALC IC. When both the

ready signal and LOC signal are available to the

transmit ALC IC, the switching transistor for the RF

power amplifier is turned on.

A coupler module samples the forward power and

the reverse power of the PA output voltage. Reverse

power is present when there is other than 50 Ω imped-

ance at the antenna port. Sampling is achieved by

coupling some of the forward and/or reverse power for

rectification and summing. The resulting DC voltage

is then applied to the transmit ALC IC as an RF

strength indicator.

The transmit ALC circuit is the core of the power

control loop. Circuits in the transmit ALC module

compare the RF strength indicator to a reference value

and generate a bias signal that is applied to the base of

a transistor. This transistor varies the DC control

voltage applied to the RF PA controlling the RF

power.

4.4 DIGITAL BOARD

4.4.1 INTRODUCTION

The Digital Signal Processing (DSP) functions

are performed by the DSP chip (U12) and the ADSIC

(U3) with the support of FLASH (U2) and SRAM

(U5, U6) memory devices. Functions previously

performed in hardware like filtering and limiting are

performed by software running in the DSP chip. The

digital board connects with the Keypad Board via J4

and with the RF board via J1.

4.4.2 DIGITAL SIGNAL PROCESSING

OVERVIEW

The DSP section consists of a DSP chip (U12),

the ADSIC (U3), two 128K x 8-bit Static RAM chips

(U5, U6), one 512K x 16-bit FLASH ROM memory

chip (U2), a UART chip (U7), a programmable logic

IC (U1), and two glue-logic chips (U4, U9). The

FLASH ROM contains the program code executed by

the DSP. Depending on the operational mode selected

for the radio, different sections of the program code in

the FLASH ROM are copied into SRAM for faster

execution.

The ADSIC is a support chip for the DSP. It

provides the interface between the DSP and the analog

signal paths, and between the DSP and the ABACUS

chip on the RF Board. Configuration of the ADSIC is

handled primarily by the microcontroller. The DSP has

access to a few memory-mapped registers on the

ADSIC.

In receive mode, the ADSIC interfaces the DSP

with the ABACUS IC on the RF Board. The ADSIC

collects the I and Q samples from the ABACUS and

performs channel filtering and frequency discrimina-

tion on the signals. The resulting demodulated signal

is routed to the DSP via the serial port for further

processing. After the DSP processing, the signal is

sent to the ADSIC Speaker D/A by writing to a

memory- mapped register. The ADSIC then converts

the processed signal from the DSP to an analog signal

and then outputs this signal to the speaker power

amplifier on the keypad board.

In transmit mode the ADSIC Microphone A/D

digitizes the analog signal from the microphone. The

DSP reads these values from a memory-mapped

sends the modulation signal to the ADSIC via the

serial port. In the ADSIC, the VCO D/A converts the

sampled modulation signal into an analog signal and

then routes this signal to the VCO on the RF Board.

4.4.3 RECEIVE SIGNAL PATH

The ABACUS IC on the RF Board provides a

digital back end for the receiver section. It provides a

digital output of I (in phase) and Q (quadrature)

samples which represent the IF signal at the receiver

back end. These samples are routed to the ADSIC

where the signal is filtered and frequency discrimi-

nated to recover the modulating signal.

The recovered signal is sent to the DSP chip for

processing. The ADSIC interface to the ABACUS is

comprised of four signals SBI, DIN, DIN*, and ODC.

The ODC signal is a clock the ABACUS provides to

the ADSIC. Most internal ADSIC functions are

clocked by this ODC signal at a rate of 2.4 MHz and

are available as soon as the power is supplied to the

circuitry. This signal initially may be 2.4 or 4.8 MHz

after power-up. It is programmed by the ADSIC

through the SBI signal to 2.4 MHz when the ADSIC is

initialized by the microcontroller through the SPI bus.

For any functionality of the ADSIC to exist, including

initial programming, the reference clock must be

present.

SBI is a programming data line for the ABACUS.

This line is used to configure the operation of the

ABACUS and is driven by the ADSIC. The microcon-

troller programs many of the ADSIC operational

features through the SPI interface. There are 36

configuration registers in the ADSIC of which 4

contain configuration data for the ABACUS. When

these particular registers are programmed by the

microcontroller, the ADSIC in turn sends this data to

the ABACUS through the SBI.

DIN and DIN* are the data lines in which the I

and Q data words are transferred from the ABACUS.

These signals make up a differentially encoded current

loop. Instead of sending TTL-type voltage signals, the

data is transferred by flowing current one way or the

other through the loop. This helps reduce internally

generated spurious emissions on the RF Board. The

ADSIC contains an internal current loop decoder

which translates these signals back to TTL logic and

stores the data in internal registers.

The ADSIC performs digital IF filtering and

frequency discrimination on the signal, sending the

baseband demodulated signal to the DSP. The internal

digital IF filter is programmable with up to 24 taps.

These taps are programmed by the microcontroller

through the SPI interface.

The DSP processes this data through the SSI

serial port. This is a six-port synchronous serial bus.

The ADSIC transfers the data to the DSP on the TxD

line at a rate of 2.4 MHz. This is clocked synchro-

nously by the ADSIC which provides a 2.4 MHz clock

on SCKT. In addition, a 20 kHz interrupt is provided

on TFS to signal the arrival of a data packet. This

means a new I and Q sample data packet is available to

the DSP at a 20 kHz rate which represents the

sampling rate of the received data. The DSP then

processes this data to extract audio, signaling, and

other information based on the 20 kHz interrupt.

In addition to the SPI programming bus, the

ADSIC also contains a parallel configuration bus. This

bus is used to access registers mapped into the DSP

memory. Some of these registers are used for addi-

tional ADSIC configuration controlled directly by the

DSP. Some of the registers are data registers for the

speaker D/A. Analog speaker audio is processed

through this parallel bus where the DSP outputs the

speaker audio digital data words to this speaker D/A.

In addition, an analog waveform is generated which is

output to SDO (Speaker Data Out).

In conjunction with speaker D/A, ADSIC

contains a programmable attenuator to set the rough

signal attenuation. However, the fine levels and differ-

ences between signal types are adjusted through the

DSP software algorithms. The speaker D/A attenuator

setting is programmed by the microcontroller through

the SPI bus.

The ADSIC provides an 8 kHz interrupt to the

DSP on IRQB for processing the speaker data

samples. This 8 kHz signal must be enabled through

the SPI programming bus by the microcontroller and is

necessary for any audio processing to occur.

4.4.4 TRANSMIT SIGNAL PATH

The ADSIC contains an analog-to-digital (ADC)

converter for the microphone. The microphone path in

the ADSIC also includes an attenuator that is

programmed by the microcontroller through the SPI

bus. The microphone input in the ADSIC is on pin

MAI (U3-19). The microphone ADC converts the

analog signal to a series of data words and stores them

in internal registers. The DSP accesses this data

through the parallel data bus. As with the speaker data

samples, the DSP reads the microphone samples from

registers mapped into its memory space. The ADSIC

provides an 8 kHz interrupt to the DSP on IRQB for

processing the microphone data samples.

The DSP processes these microphone samples

and generates and mixes the appropriate signaling and

filters the resultant data. This data is then transferred

to the ADSIC on the DSP SSI port. The ADSIC gener-

ates a 48 kHz interrupt so that a new sample data

packet is transferred at a 48 kHz rate and sets the

transmit data sampling rate at 48 ksps. These samples

are then input to a transmit D/A which converts the

data to an analog waveform. This waveform is the

modulation signal from the ADSIC and is connected to

the VCO on the RF Board.

4.4.5 DSP CHIP (U12)

DSP chip U12 has a 16-bit data bus and a 16-bit

address bus. It has 10K words of internal SRAM from

which 0.5K are used only to store data and 9.5K are

used either for data or for program storage. The DSP

bus can access through its buses the following external

devices:

SRAM U5 and U6 - These two chips are 128K x 8

chips. U5 stores the lower byte of the word while U6

stores the higher byte. Those chips are selected by

asserting CE2 high and CE1* low. The programmable

logic IC is responsible for controlling the select lines

of these ICs.

FLASH ROM U2 - This chip is 512K x 16 words in

size. It is selected by asserting CE* low. The program-

mable logic IC is responsible for controlling the select

line of this IC.

ADSIC U3 - The ADSIC contains several registers

which can be read from or written to by the DSP. The

ADSIC IC has an output which drives a data/address

bus enable signal for the programmable logic IC.

UART U7 - This chip converts data from the DSP into

serial data. It is used to interface with the optional

encryption board.

Programmable Logic U1 - This IC arbitrates access

to the DSP’s address/data bus between the flash (U2),

SRAMs (U5,U6), and UART (U7). The DSP can

modify the memory configuration by writing to a

series of registers in the programmable logic IC. In

order to reduce power consumption, the programmable

logic IC can be “disconnected” from the DSP’s

address/data bus using the bus enable input on the

programmable logic IC (pin 44).

The DSP uses memory as data space, program

space, and I/O space as follows. Refer to Figure 4-3

for more information.

Program Space - Internal SRAM, external SRAM,

and FLASH memory.

Data Space - Internal SRAM and external SRAM.

I/O Space - Programmable logic IC, ADSIC, and the

UART.

The DSP accesses the difference spaces by setting

the corresponding lines PS*, DS*, IS* low. Only one

of these three signals can be low at a given time. When

the DSP accesses internal SRAM, none of these lines

is activated.

The programmable logic IC (PLD) acts as the

primary arbitrator of the DSP’s memory map. The

FLASH ROM and the SRAM are both mapped in the

program space and cannot both be active at the same

time. The DSP may control which type of memory is

mapped in program space by enabling the program-

mable logic IC (PLD), then manipulating a register in

the PLD. In addition, the DSP can manipulate other

registers to control paging of both the Flash and the

SRAM. Paging refers to the swapping of 64K word

blocks of Flash or SRAM into or out of the DSP’s

memory map.

FLASH ROM U2 is used to permanently store

the program to be executed in the DSP. However, it is

slow to access, so to fully utilize the speed of the DSP,

the program stored in the FLASH ROM must be

copied into the SRAM. As the size of the SRAM is

half the size of the FLASH ROM, only the code

required for the current mode of operation is copied in

the SRAM. As previously mentioned, the FLASH

ROM and the SRAM cannot be active at the same

time. Thus we use the internal data memory as a

temporary buffer to transfer the program from the

FLASH ROM to the SRAM.

The following hardware interrupts are used on the

DSP:

Connector J2 allows connection to an emulator

for debugging purposes. The emulator connects to

some dedicated pins on the DSP.

phone ADC from ADSIC

Part No. 001-5100-001

4.4.6 UART

The UART performs parallel to serial and serial

to parallel conversion. The serial format used is a 9-bit

format with start and stop bits. The serial transmission

speed is 19200 bps. The UART appears as eight regis-

ters visible in the I/O space of the DSP starting at

every multiple of 0008h from 0000h to 07FFh. U11

performs the address decoding by selecting the UART

when both IS* and A15 are low. Crystal Y2 along with

the internal oscillator of the UART provides the clock

required to generate the correct bit rate on the serial

output of the UART.

When the UART receives a new serial word or is

ready to accept a new word to send from the DSP, it

generates an interrupt on INTRN. This pin is

connected to one of the hardware interrupt lines on the

DSP. The DSP responds by reading the status register

in the UART and by answering accordingly.

4.4.7 ADSIC

The ADSIC is a complex custom IC which

performs many analog-to-digital, digital-to-analog,

and purely digital functions as previously described.

The ADSIC has four internal registers accessible by

the DSP. They are selected through the use of address

lines A15, A14, A13, A2, A1, A0, IS* (IS* needs to be

inverted with U4 to be compatible with the logic level

required by the ADSIC), RD*, and WR*. Two of these

registers are read-only while the two others are write-

only. Therefore, they can be accessed as two locations

in the I/O spaces. Due to the decoding performed,

those locations appear at the following addresses:

Fxx0h, Fxx1h, Fxx8h, Fxx9h, Exx0h, Exx1h, Exx8h,

and Exx9h.

Crystal Y1 along with the internal oscillator in

the ADSIC provide a 20 MHz clock. This clock signal

is used internally by the ADSIC and is also multiplied

by two to provide a 40 MHz clock to the DSP. The

frequency of the clock can be electronically shifted a

small amount by controlling varicap D1 through the

OSCW pin (U3-97). This removes interference created

on some channels by the clock.

The ADSIC and DSP exchange the sampled

receive data and the sampled VCO modulation signal

through a serial port. This serial port consists of pins

SCKR*, RFS, RxD, TxD, SCKT, and TFS on the

ADSIC. U21 and U1 modify the relative phase of TxD

and TFS to be compatible with the timing required on

the serial port of the DSP.

SDO is the output of the internal speaker DAC.

MAI is the input of the internal microphone attenuator

and is followed by the microphone ADC.

The ADSIC is configured partially by the DSP

through its data and address bus (see preceding).

However, most of the configuring is provided through

an SPI compatible serial bus. This SPI serial bus

consists of pins SEL*, SPD, and SCLK. The other side

of this bus is connected to the controller on the

Keypad Board.

4.5 KEYPAD BOARD

4.5.1 INTRODUCTION

The Keypad Board contains a microcontroller,

LCD Display, Display Driver, Audio circuits, and

Power supply. The Keypad Board interfaces with the

Digital board via J4, with the Top Control rigid flex

circuit via J13, and with the side buttons, PTT switch,

and accessory connector through J5.

4.5.2 FUNCTIONAL DESCRIPTION

The microcontroller provides an interface

between the hardware and the DSP (on the Digital

Board). When the user presses or rotates a control such

as the channel selector switch, a side option or PTT

switch, or a keypad key, the microcontroller signals

the change to the DSP. Conversely, when the DSP

needs to change the display or an LED, it signals the

microcontroller which then performs the action. The

microcontroller also controls peripheral ICs such as

the synthesizer, reference oscillator, display, and

ADSIC.

The microcontroller uses a serial bus to commu-

nicate with the DSP and another RS232 bus to

communicate with the side port connector. The side

connector bus is used for external communication with

a computer running the programming or tuning soft-

ware. Finally, the microcontroller maintains certain

operating parameters in the associated EEPROM

which is controlled via a two-wire serial bus.

DIGITAL BOARD (CONT’D)

CIRCUIT DESCRIPTION

4-12 September 2001

Part No. 001-5100-001

4.5.3 MICROCONTROLLER

The microcontroller is a Motorola

M68HC08XL36 chip. It includes 28K bytes of internal

ROM memory and 1K byte of internal SRAM. It does

not have an external bus and therefore cannot access

any external program memory.

The clock to the microcontroller is provided by

Y1 and an internal oscillator. The frequency of the

clock can be slightly offset by polarizing the base of

Q3 through software control. This prevents RF inter-

ference on some channels caused by the clock.

The microcontroller contains an SPI-compatible

synchronous serial bus. This bus consists of pins

MISO (U1-53), MOSI (U1-52), SPSCK (U1-50), and

a chip enable for each device with which it communi-

cates. The devices which communicate with the

microcontroller through this bus are as follows:

•Top Display driver chip (Top Display board)

•Front Display driver chip (Digital board)

•ADSIC chip (Digital board)

•Reference Oscillator (RF Board)

•Front-End DAC (RF Board)

•Synthesizer chip (RF Board)

•Optional DES board.

The microcontroller communicates with the DSP

chip (Digital board) through a custom serial bus. This

serial port includes pins PTA3 (U1-8), PTA4 (U1-9),

PTA5 (U1-10), PTA6 (U1-11), and PTA7 (U1-12).

The microcontroller uses its SCI asynchronous

serial bus for external communication with a computer

running programming or tuning software. The SCI

pins RxD (U1-42) and TxD (U1-43) are connected to

RS232 driver receiver U5. The other signals of a stan-

dard RS232 computer port (DSR, DTR, CTS, RTS)

are generated using microcontroller input/outputs.

The RS232 driver U5 converts signals from a

logic level of 0 and 5 V to a logic level of –10 and

+10V. The chip contains an internal charge pump to

generate –10V and +10V from the 5V power supply.

The RS232 chip can be put in standby mode by

leaving the line K/F-RS232* floating. This line is

connected to the side connector which allows it to turn

on U5 only when a computer is connected to the radio.

The keypad interfaces with the microcontroller

through eight lines (4 rows x 4 columns). The micro-

controller regularly polls these lines to detect a key

closure.

Serial EEPROM U3 is used to store some impor-

tant radio parameters. The EEPROM is read to or

written from using I/O lines PTC6 and PTC7 of the

microcontroller. PTC6 is used for the Data line, and

PTC7 is used as a clock line.

Shift register U14 expands the number of I/O

lines of the microcontroller. It uses the same data and

clock as the EEPROM plus an additional line (U1-45)

to control the latch. Other user interface inputs such as

the PTT and toggle switches are directly connected to

an I/O line of the microcontroller.

4.5.4 LOW VOLTAGE DETECT

Voltage comparator U4 detects a low voltage

condition and communicates this information to the

microcontroller through the pin PTC5 (U1-30). The

microcontroller can also detect through I/O IRQ2*

(U1-62) that a battery is connected.

4.5.5 LCD DISPLAYS AND DISPLAY DRIVERS

The radio has two displays which each have eight

characters, several icons and a backlight. One display

is located on the Keypad Board while the other display

is located on the Top Display Board. Each display is

driven by its own driver. The drivers are programmed

by the microcontroller through the SPI bus. Both

display drivers are connected to the common PI bus

but are individually addressable so that the displays

may show different information at the same time.

4.5.6 AUDIO CIRCUITS

The audio circuits on the Keypad/Display Board

consist of four op amps, two audio power amplifiers,

and an analog switch.

In receive mode, the analog receive waveform

created by the ADSIC (on the Digital Board) is fed to

an op amp summing amplifier (U9B). This amplifier

sums in the audio tones that are generated by the

microcontroller. The output of the summing amplifier

KEYPAD BOARD (CONT’D)

CIRCUIT DESCRIPTION

4-13 September 2001

Part No. 001-5100-001

is then fed through the volume control potentiometer

to a second op amp buffer.

The buffer output is routed to a pair of audio

power amplifiers: one to drive the internal speaker and

another to drive the external speaker. Only one of

these audio power amplifiers can be active at a time.

The active power amplifier is selected by the OPT

SEL 1 line (J5-12). The MUTE line turns the active

power amplifier on or off by disconnecting the battery

voltage from the audio power amplifier IC using the

transistor Q4. Transistors Q8 and Q9 and their associ-

ated RC networks remove popping sounds from the

speaker audio by delaying the unmuting of the audio

amp compared to the unMUTE command.

In transmit mode, the audio for transmission can

be selected from either an internal or external micro-

phone, depending upon the presence of an external

microphone and which PTT is pressed. An analog

switch is used to route either the internal or external

microphone signal to the microphone amplifier. The

external microphone signal is buffered by an op amp.

The microphone amplifier has a gain of ten, and is

equipped with a pair of clipping diodes to prevent the

amplified microphone signal from over-driving the A/

D input on the ADSIC.

4.5.7 VOLTAGE REGULATION

The 5-Volt Digital Supply is produced by

switching DC-DC converter U12 which operates off

the Unswitched B+ Supply. The switching frequency

is around 160 kHz. A switching regulator is used to

improve efficiency since the 5-Volt Digital Supply

power consumption is a large percentage of the total

power consumption of the radio. The peak-to-peak

residual ripple on the 5-Volt Digital supply is approxi-

mately 50 mV.

The DC-DC converter is controlled by a wired

AND gate on the Shutdown pin of the device. The two

inputs of the wired AND gate are the SW_B+ and the

output PTC4 of the microcontroller U1. When either

input is high, the DC-DC converter is operating.

The DC-DC converter has a soft-start feature

(R98, C136) to prevent chattering of the output regu-

lated voltage due to “bouncing” of the on/off switch.

The converter has current limiting that limits output

current to 1.5 A. The under voltage protection turns

the converter off if the input (Unswitched B+) voltage

drops below 5.45 V.

The 5-Volt Analog Supply is produced by a linear

regulator running from the Unswitched B+ Supply.

The Unswitched B+ input to the regulator is switched

on and off by a FET that is turned on by the 5-Volt

Digital Supply. The peak-to-peak output ripple of the

5-Volt Analog regulator is less than 10 mV which is

appropriate for analog circuits.

4.6 TRANSMIT FREQUENCY

DETERMINATION

The operational frequency of the transmitter is

determined by the PLL (Phase-Locked-Loop)

consisting of synthesizer U204 and VCO circuit Q202/

U201. Reference oscillator U203 generates and

supplies a reference signal of 16.8 MHz to synthesizer.

The synthesizer contains a programmable reference

divider, programmable A and B dividers, a program-

mable prescaler counter (P), and a programmable frac-

tional N divider with two programmable values (N

numerator and N denominator).

All of these dividers are programmed through the

serial interface which connects the synthesizer to the

controller microprocessor. The 16.8 MHz reference

oscillator frequency is divided down to a synthesizer

reference frequency of 2.1, 2.4, or 2.225 MHz. This

signal is fed to the phase detector which generates the

steering voltage for the VCO. The output of the VCO

circuit is coupled back and divided by AP+B and then

divided by the fractional divider and fed into the

second input of the phase detector. The VCO buffer

has two outputs. One input goes to the input of Rx

mixer chip U2, and the other is applied to the input of

power amplifier module U105.

4.7 HARMONIC FILTER

The transmitter harmonic filter consists of C148-

C151, L126, L127, and L128.With VHF models only,

it also consists of C129 and C130. The circuit is essen-

tially a seven-pole low-pass filter. With VHF units

only, two additional poles are inserted by C129 and

C130 which are series resonant with L126 and L127.

The following alignment procedure should be

performed if repairs are made that could affect the

factory alignment or if adjustments may have changed

for some other reason.

To perform transceiver alignment, a PC-compat-

ible computer, the programming interface cable, and

PCTune software are required (see Table 1-1). In addi-

tion, to adjust the squelch level, the Radio Interface

Box (RIB) and radio-to-RIB cable are required. The

programming setup is shown in Figure 5-1.

All adjustments are set digitally using the

computer. Therefore, there is no need to disassemble

the transceiver to access adjustment points. In addi-

tion, audio test signals are generated internally, so an

audio generator is not required. The required test

equipment is shown in Figure 5-1.
