<p>A timing generating device, in which a period generator generates pulses the average period of which is equal to a preset period, at intervals of an integral of a reference clock period T, and provides fractional period data which indicates the phase difference between the above pulses and pulse of the preset period for each of them. From a coarse delay circuit (16) is yielded a pulse delayed behind the former pulse according to coarse delay data in a preset delay amount which indicates a value greater than the reference clock period T. Fractional delay data in the preset delay amount which indicates a value smaller than the reference clock period, and the fractional period data are added together (83). By the added output the delayed pulses from the coarse delay circuit is delayed in a fine delay section (18) by a value corresponding to the added value, producing a timing pulse. </p> |
