ABSTRACT:
A synchronizing circuit provides a plurality of signal transmission paths having different delay times in the line for transmitting signals. A pilot signal circuit has a pilot signal generator circuit which operates on the sending side, and a pilot signal is sent via one of the paths having a different delay time to a plurality of latch circuits on the receiving side. The output of each of the latch circuits is compared by a predicting circuit, so as to predict the phase difference between the clock signals of sending clock system and the receiving clock system. According to the result of this prediction, the signal transmission path having the optimum delay time is selected, so as to transmit the received signal that has been synchronized to the latch on the receiving side.
