ABSTRACT:
A circuit comprising a sampling logic to sample an incoming signal. A phase detection logic to determine a phase error associated with the sample of the incoming signal and to output an out-of-phase detection signal based on the phase error. A control logic coupled to the phase detection logic to output a periodic error signal at a periodic rate. A phase adjustment logic to adjust the phase of the sampling logic based on the out-of-phase detection signal and the periodic error signal.
