Patent ID: 7580691

Claim:
A system comprising: a receiver comprising downconversion circuitry adapted to convert a radio frequency (RF) signal into a downconverted signal using at least one local oscillator frequency signal; digital circuitry operating based on at least one clock signal and adapted to process the downconverted signal; a frequency synthesizer adapted to provide an output frequency signal based on a reference frequency and a control signal, wherein the at least one local oscillator frequency signal is a function of the output frequency signal; and divider circuitry adapted to divide the output frequency signal to provide the at least one clock signal based on at least one divide value provided such that at least one harmonic of the at least one clock signal is offset from a center frequency of the RF signal by at least a minimum frequency offset, and the at least one harmonic of the at least one clock signal nearest to the center frequency of the RF signal is substantially unchanged as the receiver is tuned from a first frequency channel to a second frequency channel by controlling the output frequency signal of the frequency synthesizer using the control signal.
