Abstract
A clock and data recovery circuit includes a sampling module, a phase detect module, a parallel-to-serial converter and a phase adjust module. The sampling module generates a data signal and an edge signal according to input data, a first clock signal and a second clock signal. The phase detect module detects a phase of the data signal and a phase of the edge signal to generate first output recovered data and a first phase adjust signal. The parallel-to-serial converter performs a parallel-to-serial conversion on the first recovered data and the first phase adjust signal, so as to generate second output recovered data and a second phase adjust signal. The phase adjust module generates the first clock signal and the second clock signal, and adjusts the first clock signal and the second clock signal according to the second output recovered data and the second phase adjust signal.
