Abstract
A radio frequency (RF) receiver comprises an analog receiver, a digital processor, and a clock synthesizer. The analog receiver has an input for receiving an RF input signal, and an output for providing a digital intermediate frequency (IF) signal. The digital processor has a first input for receiving the digital IF signal, a second input for receiving a clock signal, a signal output for providing an IF output signal, and a control output for providing a clock control signal. The clock synthesizer has an input for receiving the clock control signal, and an output for providing the clock signal. The digital processor controls a frequency of the clock signal dynamically in response to a channel selection input to reduce interference of sub-harmonics created by the digital processor on the analog receiver.
