Abstract
A timing reproduction device includes a timing error detector for detecting an error in timing of a signal transferred between a transmission side and a reception side on the basis of a received signal and for generating a timing error signal. An integrator integrates the timing error signal to thereby hold data necessary to maintain a timing synchronization. A sensing unit senses abrupt timing change in the received signal. A timing synchronizing unit executes a timing synchronizing operation for maintaining the timing synchronization by referring the data held in the integrator. A cutoff unit executes a cutoff operation which prevents the timing error signal from being applied to the integrator on the basis of the abrupt timing change sensed by the sensing unit.
