Transmitter, receiver, and clock transfer method

Abstract

A transmitter includes a memory, and a processor configured to generate a first clock parallel signal by performing serial-parallel conversion of a first clock signal acquired by using a reference clock and generate a second clock parallel signal by performing serial-parallel conversion of a second clock signal acquired by using the reference clock, generate first compressed information by compressing the first clock parallel signal on the basis of clock periodicity and generate second compressed information by compressing the second clock parallel signal based on the clock periodicity, generate a serial signal by adding a synchronization signal indicating a top of a multiplexed signal to the multiplexed signal generated by time-division multiplexing of the first compressed information and the second compressed information, and transmit the serial signal to a receiver.
