The Tx signal output from the modem.
A bias line for the internal circuitry, held at
½ V_DD. This pin must be decoupled to V_SS by a
capacitor mounted close to the device pins.
The input to the Rx input amplifier.
The output of the Rx input amplifier and the input
to the Rx RRC filter.
The positive supply rail. Levels and voltages are
dependent upon this supply. This pin should be
decoupled to V_SS by a capacitor.
Notes: I/P = Input
O/P = Output
BI = Bidirectional
Internal protection diodes are connected from each signal pin to V_DD and V_SS.
