摘要： The operation range of a phase detector provided with a flip-flop is improved, and the jitter tolerance of a receiving circuit is enhanced. The phase detector includes a holding unit and a detection unit. In the phase detector, the holding unit holds an input signal in synchronization with a predetermined periodic signal. The detection unit detects a phase difference between a designated edge and the predetermined periodic signal on the basis of a signal held in the holding unit. The designated edge is designated by a control signal that designates one of a rising edge and a falling edge of the input signal as the designated edge.
