<p><P>PROBLEM TO BE SOLVED: To provide a device capable of obtaining the timing of synchronization among respective network nodes with simple constitution. <P>SOLUTION: Disclosed is the synchronising device for network nodes such that a slave 2n receives specified synchronoous pattern data sent by a master 1 in specified timing by simultaneous broadcasting. A data reception part of the slave 2n is equipped with a receiving circuit which outputs a reception completion signal from a receiving circuit 400 each time data reception is completed, a timer circuit 407 which is actuated according to the reception completion signal to output a time-over signal 408 a specified time later, and a synchronous pattern detection processing part which generates a pattern matching signal when data read out of the receiving circuit are a specified synchronous pattern and regenerates a mster synchronizing signal by ANDing the pattern matching signal and time-over signal. <P>COPYRIGHT: (C)2004,JPO</p> |
