<p>PURPOSE:To eliminate the need for complicated constitution such as duplicate constitution of memories or the like or a reset signal generating circuit or a delay circuit by generating a data of positive and reverse phase with a positive reverse phase data generating section and selecting 2 kinds of data. CONSTITUTION:A positive reverse phase data generating section 2 inputs an output at a terminal Q of an F/F circuit 11 to terminals D of 2 F/F circuits 21, 22 to connect the output from the terminal Q to input terminals A, B of a selection circuit 31 respectively. The output of the terminal Q of the F/F circuits 21, 22 is data having positive and negative half phase difference. A phase comparison section 5 receives an output signal at an output terminal Y of a selection circuit 32 and an in-station clock and compares them and outputs a phase coincidence signal when they are coincident. The switching operation is executed by the selection circuit 31 with the phase coincidence signal to switch the positive reverse phase of the output data and outputs the result, then a stored data is outputted as an in-station data in matching with the in-station phase by the in-station clock.</p> |
