XCEN

I (CMOS)

Transceiver Enable Input. Enables the bandgap reference and voltage

regulators when high. Consumes only leakage current in STANDBY

mode when low. This is a CMOS input, and the thresholds are

referenced to VCCA and VSSMX.

TXON

I (CMOS)

TX/RX Control Input. Switches the transceiver between TRANSMIT and

RECEIVE modes. Circuits are powered up and signal paths reconfigured

according to the operating mode. This is a CMOS input, and the

thresholds are referenced to VCCA and VSSMX.

RXGN

I (CMOS)

Gain Step Input Control. Switches the receiver between high gain (when

HIGH) and low gain (when LOW). This dual-gain design allows the

system designer to achieve low noise figure for low input signals while

maintaining a good IIP3 under high input signal conditions. This is a

CMOS input, and the thresholds are referenced to VCCA and VSSMX.
