ABSTRACT:
A system on a chip integrated circuit includes an analog front end for receiving a received radio signal having a plurality of channel signals, each of the plurality of channel signals being modulated at one of a corresponding plurality of carrier frequencies, and for converting a selected one of the plurality of channel signals into a digital signal. A digital clock generator generates a digital clock signal at a digital clock frequency that varies based on the selected one of the plurality of channel signals. The digital clock frequency, and integer multiples of the digital clock frequency, are not substantially equal to the carrier frequency of the selected one of the plurality of channel signals. A digital section converts the digital signal into at least one audio signal that corresponds to the selected one of the plurality of channels, based on the digital clock signal.
