Abstract
A clock recovery circuit includes a reference clock generation unit that generates a reference clock subjected to SSC modulation, a clock recovery unit that recovers an SSC modulated clock of a data signal subjected to the SSC modulation in synchronization with the reference clock, and a modulation signal generation unit that generates a modulation signal based on cycle information indicating a cycle of a FM demodulated signal obtained by performing FM demodulation on the SSC modulated clock recovered by the clock recovery unit and slope information indicating a slope of the FM demodulated signal, in which the reference clock generation unit generates the reference clock by performing the SSC modulation on a clock of a VCO with the modulation signal, and feeds back the reference clock subjected to the SSC modulation to the clock recovery unit.
