A radio-frequency (RF) receiver includes a receiver analog circuitry and a receiver
digital circuitry. The receiver analog circuitry resides within a first integrated
circuit and the receiver digital circuitry resides within a second integrated circuit.
The second integrated circuit couples to the first integrated circuit via a one-bit
digital interface. The receiver analog circuitry receives an RF signal and processes
the received RF signal to generate a digital signal. The receiver analog circuitry
provides the digital signal to the receiver digital circuitry. The receiver digital
circuitry includes a digital down-converter circuitry that mixes the digital signal
with an intermediate frequency (IF) local oscillator (LO) signal to generate a
digital down-converted signal. The receiver digital circuitry also includes a digital
filter circuitry that filters the digital down-converted signal to generate a filtered
digital signal.
