Description
50-ohm RF Input
Analog Ground
No Connection
Channel Select 0
Channel Select 1 / Serial Select Clock. Channel Select 1
when in parallel channel selection mode, clock input for
serial channel selection mode.
Channel Select 1 / Serial Select Data. Channel Select 2
when in parallel channel selection mode, data input for
serial channel selection mode.
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.
Received Signal Strength Indicator. This line will supply an
analog voltage that is proportional to the strength of the
received signal.
Mode Select. GND for parallel channel selection, V_CC for
serial channel selection
