GENERAL/CIRCUIT DESCRIPTION
GENERAL PLL CIRCUIT
The TR-7625 1s a 25W, multl channel (800channels) FM The TR 7625 employs a PLL clrcult uslng SM5111A lC for
transceiver coverlng 144 - 147995 Nl Hz It features a programmable counter, reference osc~llator frequency
bulltin repeater shift clrcult and memory circuit and dlv~der and phase detector Frequency d~v~s~onratlo
provlslon for connect~onof an opt~onal(m~cro-processor) memory and remote ~nd~cat~onfunct~onsare all controlled by
remote control BCD codes

CIRCUIT DESCRIPTION
1. Phase Locked Loop
The 130 MHz signal from Q27 passes through the
buffer circuit
028 and is then divided into a synthesizer
output by
Q11 and a loop output by 012 respectively.
The output from
Q12 is mixed with the local osc~llator
output, tr~pledby Q6. D21 and Q20 to obtain IF
frequency. The IF output is amplified by
Q19 and is fed
to
015 where the output is frequency d~v~dedas
spec~f~edby the BCD code and compared with the 10
kHz reference frequency (1/1024 of 10.240 MHz)
The DC output thus obtained passes through the
4. Memory Shift Circuit
The memory sh~ft(M) IS a circu~tto shift to the memory
frequency during transm~ssion.
CONTROL UNIT
Frequency settlngs are accomplished by the MHz. 100 kHz
and
10 kHz rotary switches. The relat~onshipbetween the
frequency and frequency divis~on1s shown below.

The local oscillator kHz order frequency can be (switch)
shifted. Frequency d~v~s~on,set bythe rotary sw~tch,
IS stored
in the latch IC's
1, 2 and 3 by pressing the memory Input
switch. The output from the latch circuit is fed through IC's
4. 5 and 6 inthe selector c~rcuittothe PLL circu~tby pressing
the memory call switch. When this switch is notpressed, the
output 1s fed directly to the PLL circu~t Memory funct~on
IS
effected by latching each sw~tchThe Information from each
sw~tch IS stored by presslng the memory switch.
The stored information remains the same unless the memory
switch 1s pressed once again. Selection of memory output
and rotary output 1s accomplished by the selector c~rcuit.
A
latched output 1s obtained by pressing the memory output
switch.
The s~gnalto the PLL circuit passes through the LED driver
clrcuit and is digitally indicated by LED.
