Abstract

A clock frequency divider is provided which has first through Pth (where P is an integer) sub-counters, each capable of counting M+1 clock pulses and provided in parallel, and first through Pth clock signals are provided to the sub-counters, which has same period as a reference clock signal and are sequentially shifted by 1/P of the period of the reference clock signal. Of the first through Pth sub-counters, when the Nth sub-counter (where N is an arbitrary number from 1 to P) finishes counting a prescribed number M of reference clock pulses, all the other sub-counters are initialized, or, at least the (N+1)th sub-counter is initialized.
