METHOD FOR PROVIDING CLOCK SIGNAL IN DATA LINK, AND APPARATUS

Provided in the embodiments of the present disclosure are a method for providing a clock signal in a data link, and an apparatus. The method comprises: in each clock domain among a plurality of clock domains of a data link, generating a reset pulse signal on the basis of an input synchronization reference signal and an input clock signal, generating an output synchronization reference signal on the basis of the input synchronization reference signal and the input clock signal, and generating an output clock signal on the basis of the input clock signal; and, by means of the reset pulse signal, resetting the output synchronization reference signal and the output clock signal, such that after the end of the reset pulse signal, a reset output synchronization reference signal and a reset output clock signal are synchronously generated at the next rising edge of the input clock signal, and are transmitted to the next clock domain via the same time delay, so as to serve as an input synchronization reference signal
