Patent ID: 7787569

Claim:
A radio frequency integrated circuit (RFIC) comprising: a low noise amplifier coupled to amplify an inbound radio frequency (RF) signal to produce an amplified RF signal; a down conversion module coupled to convert the amplified RF signal to a down converted signal based on a local oscillation; an analog to digital conversion (ADC) module coupled to convert the down converted signal into a digital signal; a baseband processing module coupled to convert the digital signal into inbound data, wherein at least one function of the baseband processing module is clocked by a plurality of baseband clock signals wherein the at least one function of the baseband processing module includes at least one of intermediate frequency to baseband conversion, fast Fourier transform, demapping, deinterleaving, decoding, and descrambling; and a clock module coupled to produce the plurality of baseband clock signals, wherein the clock module detects an interference condition when frequency dependent noise components associated with at least one of the plurality of baseband clock signals are inside a frequency band associated with the inbound RF signal, and that spreads the spectrum of the at least one of the plurality of baseband clock signals when the interference condition is detected.
