The negative differential RF signal input pin. This pin should be AC grounded with a
capacitor to ground.
Not internally connected.
Not internally connected.
Not internally connected.
Not internally connected.
3.3 V power supply pin for the RF section.
Not internally connected.
Not internally connected.
Serial address select pin. This pin has an internal pull-up, so an open on this pin will be
a logic level high (default address of 54) and a short to ground will be a logic level low
(address of 14).
Crystal bias select pin. Leave floating for operation with a 40 MHz third-overtone
crystal. This pin has an internal 30 kΩ pull-up resistor.
3.3 V power supply for the prescaler section.
The exposed paddle at the bottom of the chip is the common chip ground and the
thermal conductor.
