Abstract: The present disclosure discloses a clock and data recovery circuit. The clock and data recovery circuit may include a clock recovery unit configured to output a recovery clock signal by operating a first time-to-digital conversion circuit or a second time-to-digital conversion circuit depending on a phase difference between a clock of an input signal and the recovery clock signal, and a data recovery unit configured to sample data from the input signal and output recovery data.
