摘要：Clock data recovery can be accomplished using a phase change determinationcircuit that generates, based upon detected phase differences between a capture clocksignal and data signal, a delta signal and a delta selection signal. A calculation circuitgenerates a set of phase interpolation (PI) codes from prior and speculative values of thedelta signal. A selection circuit selects, in response to the delta selection signal, betweenthe sets of PI codes, which are provided as an output of the clock data recovery device.
