ABSTRACT:
A system and method for tracking/adapting phase or frequency changes in an incoming serial data stream that may contain significant amounts of noise and/or jitter and may contain relatively long periods of successive univalue data bits. The method includes digitally sampling a received data stream at predefined intervals to produce a data set; estimating when logic transitions occur in the data set; detecting a timing trend represented by the estimated logic transitions; and adjusting a frequency of the first clock so that the timing trend averages approximately zero over a plurality of logic transitions.
