A phase and frequency detector compares phases and frequencies of the clock signal generated by the VCO and an input signal. A charge pump adjusts a control voltage of the VCO based on an output of the phase and frequency detector. An identical digit detector generates a first signal by delaying a rising timing of the input signal by a first time, generates a second signal by delaying a falling timing of the input signal by a second time, detects succession of identical digits in the input signal based on the first signal and the second signal, and stops adjustment of the control voltage by the charge pump when the identical digits succeed by a predetermined number of identical digits or more."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Clock recovery circuit, optical module, and clock recovery method","description":"A VCO generates a clock signal.
