Abstract
The present disclosure discloses a time-to-digital conversion circuit for a clock and data recovery circuit. The time-to-digital conversion circuit may include a first time-to-digital conversion circuit enabled when a phase difference between a clock of an input signal and a recovery clock signal is greater than a reference phase difference and configured to output a first digital signal corresponding to the phase difference, and a second time-to-digital conversion circuit enabled when the phase difference is equal to or smaller than the reference phase difference and configured to output a second digital signal corresponding to the phase difference.
