Abstract
A clock data recovery circuit is provided. The clock data recovery circuit includes a charge pump circuit, a voltage controlled delay line circuit, a charge pump current generator, a phase-frequency detector and a frequency detector. The charge pump circuit generates a control voltage according to a first control signal, a second control signal and a charge pump current. The voltage controlled delay line circuit generates a data clock signal according to the control voltage and a reference clock signal. The charge pump current generator generates the charge pump current to the charge pump circuit according to the control voltage. The phase-frequency detector generates the first control signal according to a feedback clock signal and the reference clock signal. The frequency detector generates the second control signal according to the feedback clock signal and the reference clock signal.
