Abstract:
A clock data recovery circuit includes a first circuit, a second circuit, and a third circuit. The first circuit is configured to receive data and a clock signal and to detect transitions in the data and provide a first signal based on the clock signal and the transitions in the data. The second circuit is configured to receive the first signal and provide a first shift signal based on the first signal. The third circuit is configured to receive the first shift signal, wherein the first circuit, the second circuit, and the third circuit are configured to form a first circuit loop and the third circuit is configured to disable the first circuit loop and shift the clock signal based on the first shift signal.
