Abstract
A clock and data recovery circuit module and a phase lock method are provided. The module includes a phase detection circuit, a converter circuit and a voltage control oscillation circuit. The phase detection circuit is configured to detect a phase difference between a data signal and a feedback clock. The converter circuit is coupled to the phase detection circuit and configured to output a first phase control voltage and a second phase control voltage according to the phase difference. The voltage control oscillation circuit is coupled to the converter circuit and configured to receive the first phase control voltage and the second phase control voltage and output the feedback clock according to the first phase control voltage and the second phase control voltage.
