<P>PROBLEM TO BE SOLVED: To provide a clock and data recovery circuit which follows a frequency and a phase variation of serial data and has an excellent jitter strength characteristic in a clock and data recovery circuit. <P>SOLUTION: A feedback controller 107 composing a clock and data recovery circuit monitors a following rate of an extraction clock for a frequency and a phase variation of serial data, and performs a feedback control to an integrator 102 momently and adaptively, thereby increasing the following rate of the extraction clock and realizing an improvement of a jitter strength characteristic. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
