Abstract:
An embodiment of a clock and data recovery circuit comprising a first clock and data recovery circuit with high bandwidth and a second clock and data recovery circuit with low bandwidth is disclosed. The first clock and data recovery circuit with high bandwidth receives a data signal and a reference signal to demux the data signal into a first signal and a second signal, wherein a second data rate X bps of the first signal and the second signal is half of a first data rate of the data signal. The second clock and data recovery circuit with low bandwidth receives and reduces jitter in the first signal and the second signal to output a first recovery signal and a second recovery signal.
