Pin Descriptions
Pin Number Name I/O Description
1 ANT — 50-ohm RF Input
2 GND — Analog Ground
3 NC —
No Electrical Connection. Soldered for
physical support only.
4 GND — Analog Ground
5 V
CC
— Supply Voltage
6–9 NC —
No Electrical Connection. Soldered for
physical support only.
10 A REF O Audio RMS (Average) Voltage Reference
11 AUDIO O Recovered Analog Output
12 DATA O
Digital Data Output. This line outputs the
demodulated digital data
13 RSSI O
Received Signal Strength Indicator. This
line outputs an analog voltage that is
proportional to the strength of the received
signal.
14 PDN I
Power Down. Pulling this line low places the
receiver into a low-current state. The module
is not able to receive a signal in this state.
15–16 NC —
No Electrical Connection. Soldered for
physical support only.
