Abstract

A clock and data recovery device is provided which includes a phase detector, a charge pump unit, a loop filter unit, and a voltage controlled oscillator. The phase detector detects a phase of a data clock signal to output a comparison signal. The charge pump unit adjusts the amount of charges to be supplied according to the comparison signal. The loop filter unit accumulates the amount of charges to be supplied to output an adjustment signal. The voltage controlled oscillator generates an output clock signal variable according to the adjustment signal. The phase detector compares phases of the data clock signal and each of modulated clock signals sequentially received to output the comparison signal. The modulated clock signals are signals modulated from the output clock signal to have different phases.
