Abstract

PURPOSE:To decrease the number of necessary FF's and also elevate the ulitization efficiency of the circuit, by connecting in series an oscillator, a number of 1/2- frequency dividers and 1/2.5-frequency dividers, and suitably selecting these frequency dividing outputs. CONSTITUTION:The output of the oscillator 11 is frequency-divided in order by means of a lot of 1/2-frequency dividers 12 and 1/2.5-frequency dividers 16, and the necessary frequency dividing output is selected suitably and is output, by the multiplexer 15. In this way, since the 1/2.5-frequency divider can be constituted of two FF's, the number of FF's can be decreased.
