摘要：A digital signal reproduction circuit is capable of controlling a transfer functionof a waveform equalization circuit so that a synchronous clock can be generated with anoptimal transfer characteristic. The digital signal reproduction circuit (1) includes: a
waveform equalization block (10) for waveform-equalizing a regenerative signal, abinarization block (20) for binarizing the waveform-equalized regenerative signal, asynchronous clock reproduction block (30) for generating a synchronous clock from thebinarized signal, and a waveform equalization control block (40) for controlling a transferfunction of the waveform equalization block (10) according to a jitter componentbetween the synchronous clock and the binarized signal. The waveform equalizationcontrol block (40) is supplied with a phase difference signal between the binarized signaland the synchronous signal so as to obtain an optimal value of the transfer function ofthe waveform equalization block (10) by using a microcomputer, for example. Thetransfer function is controlled so as to reduce the jitter component of the synchronousclock.
