OUTPOL, VCC . Figure 2 shows the jumper diagram for the board. 5 Shunt JU4 connecting R3 = 82 RTH . 6 Shunt JU6 connecting R7 = 10k RLOS . 7 Shunt JU5 connecting pin LOS to DISABLE. 8 Connect TP2 to VCC. 9 Shunt jumper JU11 so that the capacitor C12 is connected to pins CAZ1 and CAZ2. 10 Connect the power-supply ground to the GND pad and then connect a +3.3V power supply to the VCC. 11 Observe a limited signal at the output, roughly 0.8Vp-p. 12 Lower the amplitude of the input signal from 500mVp-p to 15mVp-p or less. The output signal is squelched. and Control Descriptions see Quick Start first NAME JU2, JU3, JU4 JU5 JU6 JU7 JU8 JU9 FUNCTION Selects loss of signal assert/deassert level. Shunt to connect the LOS pin to the DISABLE pin Squelch Shunt to connect series resistor from LOS to test point TP2. Make sure TP2 is connected to a positive supply. Shunt to connect RSSI output to RSSI resistor R8.
