Abstract
A digital signal reproduction device including a data strobe circuit high in margin against noise and rapid in recovery from dropout of data and a digital signal reproduction method performed in such device. The digital signal reproduction device includes a pair of data strobe circuits and a switching circuit for selecting one of the outputs of the pair of data strobe circuits, and a circuit for generating from the received signal a signal to control the switching circuit. The data strobe circuits ensure high reliability of the received signal against noise and a short time from dropout of the received signal to acquisition of a reproduction clock. The data strobe circuit is selectable which is suitable for the reproduction state of the reproduced signal.
