Abstract: A clock data recovery circuit includes the following elements: a phase detector for outputting a phase adjustment signal by comparing a clock signal of a first node and an input signal; a charge pump for adjusting a charge amount of a second node according to the phase adjustment signal; a first switch including one end coupled to the second node and including another end coupled to a third node; a second switch including one end which receives a bias voltage and including another end coupled to the third node; a capacitor including a first electrode coupled to the third node; third switches; and voltage control oscillators including control terminals coupled to the third node and including output terminals coupled to the first node through the third switches.
