ABSTRACT:
A communication signal receiver performs a timing adjustment function of sampling with a circuit that also reduces the amount of electromagnetic interference (EMI) emitted from the receiver. The receiver includes an analog front end circuit that samples an input modulated carrier waveform responsive to a sampling clock signal to generate a digitized replica. The timing of the sampling is responsive to a timing signal. The digitized replica is analyzed to determine an appropriate adjustment to the sampling and, thus, to the timing signal. The frequency of the sampling is changed in accordance with the timing signal as adjusted, without adjusting the phase of the sampling. In particular, the frequency of the sampling is changed by removing transitions from an input clock signal to generate the sampling clock signal.
