Receiver Gain-Control Logic Input Bit 0
Receiver Gain Select. Positive edge trigger latches digital gain inputs B0–B7 to receive A. Negative
edge trigger latches digital gain inputs B0–B7 to receive B.
Receiver B LNA Differential Input. Input is internally DC-coupled.
Receiver and Transmitter Gain-Control Logic Input Bit 4
Receiver and Transmitter Gain-Control Logic Input Bit 3
Supply Voltage for Transmitter PA Driver. Bypass with a 22pF capacitor as close as possible to the pin.
Receiver and Transmitter Gain-Control Logic Input Bit 2
Power Amplifier Driver Differential Output. The pins have internal AC blocking capacitors.
