Supply voltage selectors
The supply voltage of the RF ICs can be either 5.0 +/- 5% or 3.3 +/- 5% V. The selection on the board is done by
means of soldering the appropriate side of a copper trace selector. No switches are used, to prevent this
switching from disturbing the operation. Note that ALL supplies must be set according to the table below: If the

Description
Enables squelch mode On=Active, Off=nonactive
Selection of output. On=CML, Off=PECL
LOSTTL flag. On=LOS of Signal
Inverted LOS indicator. On=Signal, Off=LOS
Enables ‘Loop’ mode. On=’Loop’ mode, Off=‘Both’ mode
Out Of Lock. Lock on 19 MHz when Frequency Window
Detector of TZA3004 is active. On=within 1000 ppm of
frequency window, Off=without 1000 ppm frequency
window
Lock of TZA3005’ synthesizer on reference clock input
Test input: synthesizer section power down
Test input : transmit section power down
Line loopback enable input (active LOW). On = no loopback
(= normal operation), Off = loopback (serial output equals
serial input)
Diagnostic loopback enable input (active LOW). On = no
loopback (= normal operation), Off = loopback (parallel
output equals parallel input)
Out of frame enable input
Reference clock select input 0. With standard 19.44 MHz
this should be set off
Reference clock select input 1. With standard 19.44 MHz
VCXO this should be set off
4/8 bit bus width select input.
Serial data rate select STM1/STM4
Reset clean up PLL
test input : reset receive logic
test input : transmit section powerdown
master reset
Bias alarm flag. On = Alarm, Off= No Alarm.
Automatic Laser Shutdown
Resets latch of Alarm3001 to ALS connection. On = Reset,
Off = No Reset
Latched ALS active
Supply of VCXO in cleanup PLL. Disable when external
reference frequency is used
