Abstract
A clock and data recovery device that includes a first phase detector, a pulse filter, a charge pump, a loop filter and a voltage-controlled oscillator is introduced. The first phase detector generates a first phase state signal according to a data signal and a first output signal. The pulse filter adjusts the first phase state signal according to a capacitance of a loop capacitor to generate a filtered signal. The charge pump generates a pumping signal according to the filtered signal. The loop filter generates a control signal according to the pumping signal. The voltage-controlled oscillator generates a second output signal and adjust a frequency of the second output signal according to the control signal, wherein the first output signal is generated according to the second output signal.
