Abstract: A clock synchronization system and method are provided. The clock synchronization system includes: a pulse generation module, configured to receive an input first signal, perform sampling processing of the first signal to obtain a second signal, and generate a pulse signal according to the second signal; a voltage-controlled oscillator, configured to output a first output clock; the output frequency divider module, configured to perform frequency division on the first output clock, and synchronize, according to the pulse signal, the first output clock which has been subjected to the frequency division, so as to obtain a second output clock; and the synchronous output module, configured to receive the first output clock, the second output clock, the first signal, and the pulse signal, and perform synchronization processing on the first signal according to the first output clock, the second output clock and the pulse signal, so as to obtain a third signal.
