Abstract

PURPOSE:To generate on unncessary pulse for the phase difference detection output, and also to reduce the number of packages and the number of wires when constituting a circuit, by combining D type FF's. CONSTITUTION:The D type FF's - F1-F4 have a set input S and a reset input R, they become an active state at an H level, respectively, and the outputs become Q and Q'. And, the instant that a clock pulse CP is shifted from a H level to an L level, a logical level of the D input is shifted to the output Q. The input In1 and the input IN2 are provided as a clock input of F1 and F2, and a clock input of F3 and F4, respectively. Also, a signal of an H level is continuously provided to the D input of F2 and F4, respectively. F3 provides the output Q of F1 to the D input, provides the output Q of F3 to the D input of F1 and the reset input R of F2, and the output Q of F2 is provided to the set input S. F4 provides its output Q to the reset input R of F1, and obtains the output Q' of F1 by the reset input R.
