Pin Descriptions

RF IN (pin 1)

50Ω RF input from antenna, connect using shortest possible route. This input is isolated from the internal

circuit using the air gap of the front end SAW RF filter

RF GND (pin 2)

RF ground connection, preferable connected to a solid plane.

RSSI / Carrier Detect (pin 3)

The Received Signal Strength Indicator provides a DC output voltage proportional to the RF input signal. The

amplitude of the RSSI voltage increases with increasing RF signal strength. A simple transistor interface can

yield a carrier detect logic output.

GND (pin 4)

Connect to power supply ground.

AF (pin 6)

Audio frequency output. (max 40uA source)

DATA OUT (pin 7)

CMOS compatible output. This may be used to drive external decoders. To reduce any noise on this output

add a 56pF cap from this pin to GND.
