Abstract

A clock and data recovery (CDR) system that generates one or more clock signals from a received data stream and determines an optimal clock signal to associate with the incoming data stream. The system includes a candidate clock generation circuit that operates to receive the incoming data stream and generate candidate clock signals. A transition density detector circuit determines a transition density parameter associated with each of the candidate clock signals. A controller operates to determine the optimal clock signal based on the transition density parameters.
