ABSTRACT:
Methods and apparatus to provide clock resynchronization in communication networks are disclosed. An example method of clock resynchronization disclosed herein comprises determining a vote based on adjacent samples occurring within a single bit interval in a sampled data stream, wherein the vote comprises an early vote when the adjacent samples indicate a sampling phase of a sampling clock is early relative to a center position in the bit interval and wherein the vote comprises a late vote when adjacent samples indicate the sampling phase is late relative to the center position, tracking a running difference between a number of early votes and a number of late votes in a plurality of votes corresponding to a plurality of adjacent samples, and adjusting the sampling phase when the running difference reaches a threshold.
