PURPOSE:To provide a circuit in which the processing period of data is decided by a control signal, and the phase compensation of the control signal is operated without adding fixed delay to the control signal. CONSTITUTION:At the time of data transmission, a fixed pattern inserting part 22 adds a fixed pattern signal having a certain pattern to the tail of transmission data 4, and at the time of data reception, a fixed pattern detecting part 24 detects the fixed pattern signal from reception data 14, and outputs a detection signal 26. A control signal discriminating part 25 outputs ON when a reception control signal 15 is ON, and outputs ON as it is even when the reception control signal 15 is changed from ON to OFF. Then, the control signal discriminating part 25 outputs OFF only when the detection signal 26 is inputted. |
