<p>PURPOSE:To automatically adjust the phases of received data and a clock signal. CONSTITUTION:This circuit is equipped with a connector 101 for the received data, a connector 102 for a received clock, a delay element part 103, a reception part 104 which retimes the received data, a frame synchronism detection part 105 which detects frame synchronism from the data signal from the reception part 104, a frame synchronism decision part 106 which outputs a switching request signal for a delay element unless the frame synchronism is detected within a specific time, and a selector part 107 which receives the switching request signal for the delay element and switches the delay element selected by the delay element part 103 to another delay element; and the data signal and clock signal are automatically put in phase with each other.</p> |
