Setting the LOS Threshold Resistor
Jumper JU1 controls the resistor used to set the loss-of-
signal threshold. To use supplied potentiometers R6
and R7, shunt the right two pins of JU1. If a set resistor
is required, solder a resistor to R9 or R10 and shunt the
top two pins of JU1 (for R9), or the left two pins of JU1
(for R10).

*Note: U1 has an exposed pad, which requires it to be solder
attached to the circuit board to ensure proper functionality of the
part.

Enabling Squelch Function
LOS Threshold
Test point TP3 (VTH) monitors the output of the internal
op amp that sets the LOS threshold voltage.
Jumper JU2 (SQUELCH) controls the squelch function.
To enable squelch, short the jumper. To disable, leave
unconnected.
Description of Test Points
Received Signal-Strength
Indicator (RSSI)
Test point TP1 (RSSI) monitors the received signal-
strength indicator. This pin is an analog voltage propor-
tional to the input signal amplitude.
