Abstract
PURPOSE:To produce the frame clock pulse to a suitable position, by providing an FF which produces the frame clock pulse to the FF constituting n-stage self-start type ring counter. CONSTITUTION:By taking the input CL of a D-FF 301 from the output of a D-FF 103, the state of linking 8 sets of D-FF, for example, at the 12-th circulation of the 7-th phase clock pulse in the self-start type ring counter 100, is obtained. Accordingly, the propagation delya time which is the time required to become the waiting state of D-FF201 from the input CL of D-FF301 constituting the frequency dividing counter 300 via the frequency dividing circuit 302, NAND circuit 202, and inverter 203, is made shorter than one pulse time of the clock TC, allowing to pick up the frame clock pulse at a prescribed position from D-FF107.
