Patent ID: 7158574

Claim:
A radio-frequency (RF) transceiver, comprising: a first integrated-circuit device that includes a receiver analog circuitry configured to produce at least one digital receive signal from an analog radio-frequency signal, the receiver analog circuitry having a plurality of signal lines that are configurable by a control signal configured to have at least a first state and a second state; and a second integrated-circuit device that includes a receiver digital circuitry configured to accept the at least one digital receive signal from the receiver analog circuitry, the receiver digital circuitry having a plurality of signal lines that are configurable by the control signal, wherein the signal lines of the receiver analog circuitry are coupled to the signal lines of the receiver digital circuitry, and wherein the signal lines of the receiver analog circuitry and the signal lines of the receiver digital circuitry are configured as a serial interface when the control signal is in the first state, the serial interface comprising a plurality of data signals and a plurality of control signals, wherein the receiver digital circuitry includes a plurality of signal driver circuitries configured to provide the plurality of data signals and the plurality of control signals of the serial interface to the receiver analog circuitry when the control signal is in the first state.
