摘要： Retiming means for retiming an incoming data stream 2 comprising clock generation means 22 for producing a plurality of clock signals 23 having the same frequency but differing phase, and signal processing means 24 for receiving both the plurality of clock signals 23 and the incoming data stream 2 and outputting a selected one of the clock signals 23 and a retimed data stream retimed in accordance with the selected clock signal. The signal processing means 24 includes comparison means for comparing the phase of the incoming data stream with the phase of the plurality of clock signals and selecting which clock signal to use on the basis of this comparison.
