Title:
CLOCK SYNCHRONIZATION DEVICE, OPTICAL TRANSMITTER, OPTICAL RECEIVER AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/253687
Kind Code:
A1
Abstract:
A clock synchronization device, an optical transmitter, an optical receiver and a method, wherein same are used to realize flexible application in application scenarios with different transmission bandwidths. In a clock synchronization device, a digital interpolator adjusts the sampling clock frequency of a digital signal under the control of a sampling clock of a clock control circuit, so that it is no longer necessary to rely on the sampling frequency of a peripheral clock circuit; instead, the clock synchronization device adaptively tracks and adjusts the sampling clock frequency so as to ensure clock synchronization, thereby supporting flexible application in application scenarios with different bandwidth requirements.
