Abstract
PURPOSE:To obtain a proper phase sampling clock by a simple constitution, by supplying a count value output of an up-down counter to a multiplexer, and selectively controlling the clock by the count value and the extent of delay from a clock delay device. CONSTITUTION:A clock CK0 from an AFC circuit 10 is supplied to a delay device 22 through an input terminal 21, from which plural, for instance, seven clocks CK1-CK7 which have been delayed in order by prescribed minutes each are obtained. In this case, the extent of delay of the clock CK7 which is delayed most against the clock CK0 is selected shorter than 1 bit period of a reproducing data, that is to say, 1 period of the clock CK0. As for the clocks CK1-CK7 from said delay device 22, and the clock CK0, a clock of phase suitable for sampling a data is selected by a multiplexer 23, and is used as a data sampling clock. According to such a constitution, a proper phase sampling clock is obtained exactly.
