Title:
ＣＤＲ制御回路、ＣＤＲ回路およびＣＤＲ制御方法
Document Type and Number:
Japanese Patent JP6592986
Kind Code:
B2
Abstract:
A CDR control circuit detects a phase shift of input data that is taken in with a phase-adjusted clock, and generates phase control data that controls the phase of the clock based on the detected phase shift, the CDR control circuit includes a change detection circuit that detects an over-change in the phase shift; and a selection circuit that outputs the phase shift before the change, which is the phase shift before the time of detection of the over-change, as the phase shift for a predetermined period of time at the time of detection of the over-change, wherein during the predetermined period of time, the phase control data is generated based on the phase shift before change.
