Abstract
First and second determination units determine amplitude levels of an input data signal in synchronization with respective first and second clocks, a phase detector detects a phase relationship between the input data signal and the second clock based on the amplitude levels, and first and second phase adjusters adjust phases of the respective first and second clocks according to a detection result of the phase detector. Further, a correction unit corrects a skew generated between the first and second clocks which arrive at the first and second determination units. A correction amount determination unit determines a correction amount corresponding to the skew in the correction unit according to the detection result in the phase detector when a phase difference set between the first and second clocks is made zero.
