Title:
BURST MODE CLOCK AND DATA RECOVERY MODULE AND METHOD, AND OPTICAL LINE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2024/067768
Kind Code:
A1
Abstract:
The present disclosure provides a burst mode clock and data recovery module, comprising: a data sampling sub-module configured to sample received data according to a clock signal, and output a sampling result to a phase determination sub-module; the phase determination sub-module configured to determine a phase determination result of the clock signal according to the sampling result; a filter circuit configured to filter, according to the phase determination result outputted by the phase determination sub-module, the phase determination result by using a bandwidth corresponding to the phase determination result; and a clock adjustment sub-module configured to adjust the clock signal according to filtered phase information, and send the adjusted clock signal to the data sampling sub-module, such that the data sampling sub-module samples the received data according to the adjusted clock signal. The present disclosure further provides a burst mode clock and data recovery method and an optical line terminal.
