PROBLEM TO BE SOLVED: To reduce increase in jitter due to periodic fluctuation in a power supply. SOLUTION: In the case that a phase difference of phase comparison data based on a result of sampling is large when a flip-flop FF 18 samples window data generated from a feedback clock based on a sampling clock from a selector 17, a sampled position is changed under the control of count by a counter 15 with a controller 14. |
