ABSTRACT:
This is a data reproduction circuit for receiving data and reproducing the data and its clock which has an over-sampling determination circuit for sampling the received data by a clock with frequency higher than the data rate of the received data and converting the sampled data into digital signals, a circuit for selecting and outputting the reproduced data, a phase error detection circuit for detecting a phase error from its timing deviation with the received data, based on the reproduced clock, a data selection circuit for adjusting its phase, based on the output of the phase error detection circuit, a phase adjustment circuit for adjusting the phase of the reproduced clock to reproduce a new clock and a clock generation circuit for supplying the over-sampling determination circuit and the data selection circuit with the newly reproduced clock.
