Abstract
A clock and data recovery (CDR) device is disclosed. The CDR device comprises a sensing unit and an interpolator. The sensing unit is configured to detect a data center, a left data edge and a right data edge of a data on a data stream in a communication system, using a set of thresholds, in response to a first clock signal for sampling the data center, a second clock signal for sampling the left data edge and a third clock signal for sampling the right data edge. Each of the thresholds is related to a different level among data levels of the data. The interpolator is configured to generate the first clock signal based on information on the data center, and generate the second clock signal and the third clock signal based on information on the left and right data edges.
