Abstract
A clock data recovery circuit of an interpolator type capable of corresponding to multi-rate data without increasing the bandwidth of the interpolator. A clock generated by an interpolator is divided to generate a recovery clock. A pointer that controls the phase of the clock generated by the interpolator uses the clock before division, and the other circuits are operated by the recovery clock after division.
