PROBLEM TO BE SOLVED: To accurately identify data even in the case of receiving data signal with high bit rate by providing an identification and reproduction circuit capable of easily accelerating its operating speed. SOLUTION: This identification and reproduction circuit is provided with a timing extracting part 4 to reproduce a clock of the received data signal from a time division multiplexed received data signal, channel selecting parts 2, 3 to increase a phase margin by adjusting the duty rate for only data signal of a specified channel among the multiplexed received data signals, phase adjusting parts 5 to 8 to adjust rise of the clock outputted from the timing extracting part 4 so that the phase coincides with a bit position of the specified channel after adjustment of the duty factor and identification and reproduction part 9, 10 to identify and reproduce the data by retiming the data signal after adjustment of the duty factor by the clock after the phase adjustment. |
