<p>The invention provides for a method of recovering a clock signal embedded in an incoming data stream. The method includes the steps of providing the incoming data stream to a data sampler circuit (14) and first operating the data sampler circuit (14) to select one of a plurality of clock phases wherein the selected clock phase is indicative of the embedded clock signal, generating a recovered clock signal based on the selected clock phase and second, operating a retiming circuit (13) in a normal data tracking mode to retime the incoming data stream based on the recovered clock signal, and disabling operation of the data sampler circuit (14) while the retiming circuit (13) is operating in the normal data tracking mode. An apparatus for recovering a clock signal which is embedded in an incoming data stream is also provided. <IMAGE></p> |
