Abstract
PURPOSE: To relieve manufacture conditions of a digital device by detecting the variation of a received digital signal, by detecting the phase difference between the output and a timing signal, and by selecting the results causing no error as to the discrimination of the input digital signal.
CONSTITUTION: Polyphase timing signal generating circuit 21 generates timing signals mutually different in phase such as S9 and S10 from reference timing signals from the same reference timing signal generating source. The variation of a received digital signal on the othe hand, is detected 12 and the phase difference between its output and signal S9 is detected by phase-difference detection circuit 14, thereby driving selector circuit 22. According to the output result of detection circuit 14, circuit 22 retimes the reception digital signal by using the timing signal, which has a phase causing no discrimination error of the input digital signal, selected by circuit 22. Consequently, the manufacture conditions of the digital device can be relieved
