Abstract
A clock recovery system includes: a sampler that samples reception data with 2N phase clocks and outputs 2N×M sampling signals; a data selector that selects n×M recovery signals from the 2N×M sampling signals and outputs the n×M recovery signals; a phase comparator that outputs, for each of the n×M recovery signals, a phase comparison signal based on the recovery signal, a first sampling signal sampled with a first clock that leads by one or more phases from a sampling clock, and a second sampling signal sampled with a second clock that delays by one or more phases from the sampling clock; a controller that designates n based on a data rate of the reception data; and a multiphase clock generator that generates and outputs the 2N phase clocks based on the phase comparison signal and n.
