Abstract
A clock and data recovery circuit that tracks the frequency and phase fluctuation of serial data includes a feedback controller for monitoring tracking speed of an extraction clock with respect to the frequency and phase fluctuation of the serial data and applying feedback control to an integrator adaptively and moment to moment, thereby raising the tracking speed of the recovered clock and improving the jitter tolerance characteristic.
