Title:
PHASE DETECTOR, PHASE SYNCHRONIZATION CIRCUIT, AND METHOD FOR CONTROLLING PHASE SYNCHRONIZATION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2017/094310
Kind Code:
A1
Abstract:
The present invention improves the operating range of a phase detector equipped with flip-flops and improves the jitter resistance of a reception circuit. This phase detector is provided with a retention unit and a detection unit. In the phase detector, the retention unit retains an input signal in synchronization with a predetermined periodic signal. On the basis of the signal retained by the retention unit, the detection unit detects a phase difference between the predetermined periodic signal and a specified edge specified by a control signal that specifies, as a specified edge, either a rising edge or a falling edge of the input signal.
