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.

摘要： An electronic circuit that includes a plurality of first drivers coupled in parallel, the first drivers each including transistors coupled in series and transmitting data at a predetermined communication speed, and a second driver that includes transistors coupled in series and transmitting data at a communication speed lower than the communication speed of the first driver. The number of first drivers operating in parallel is sufficient for output impedance of the first drivers to meet a predetermined standard through application of an electrical potential to bodies of the transistors of the first drivers. The electrical potential causes an output level of the second driver to meet a predetermined standard.
