Abstract: A clock and data recovery (CDR) circuit includes a phase detector, a phase interpolator, a finite state machine, and a divisor-controllable frequency divider. The phase detector compares an input data signal with a frequency dividing signal and generates a phase indication signal to indicate a phase difference between the input data signal and the frequency dividing signal. The phase interpolator performs phase interpolation on first and second clock signals received by the phase interpolator, so as to generate a phase interpolation signal. The finite state machine coupled to the phase detector and the phase interpolator generates the control signal based on the phase indication signal and the phase interpolation signal. The divisor-controllable frequency divider coupled to the phase detector and the phase interpolator divides the second frequency of the phase interpolation signal by a divisor so as to generate the frequency dividing signal. A CDR method is also provided.

An adaptive filter generates the reference signal and equalizer coefficients in response to data signal and the error signal. An equalizing unit generates the first feedback equalization signal and the second feedback equalization signal in response to the data signal and the equalizer coefficients.
