6 PDN I
Power Down. Pulling this line low will place
the receiver into a low-current state. The
module will not be able to receive a signal in
this state.
7 RSSI O
Received Signal Strength Indicator. This line
will supply an analog voltage that is propor-
tional to the strength of the received signal.
8 DATA O
Digital Data Output. This line will output the
demodulated digital data.
