Abstract

PURPOSE:To obtain an electronic clock circuit having logical function wide in a fast and slow width, by controlling a first and a second variable frequency dividing stages by timing different at every corresponding switches to eliminate the stage number limit of variable frequency division due to an operation delay time. CONSTITUTION:When a switch 10 resetting the flip-flop F5 of a second variable frequency dividing stage part 3 for the sake of logical fast and slow motion is operated, AND gates G1-G4 are closed through an NAND gate G7 by the high level output through a second memory circuit 5. Therefore, when logical fast and slow motion is controlled through the flip-flop F5, logical fast and slow control due to the setting and the resetting of each flip-flops F1-F4 of the first variable frequency dividing stage part 2 through switches 6-9 is inhibited. Therefore, it is unnecessary to subject the variable frequency dividing stages for logical function to delay control and the limit of variable frequency dividing stage number due to an operation delay time is eliminated to obtain an electronic clock circuit having logical fast and slow function wide in a fast and slow width.

Conventionally, logical adjustment, which varies the frequency division by setting a part of the frequency dividing circuit, has been widely used in multiple clocks, but as electronic clocks become smaller and thinner, , methods have come to be used in which the front stage of the oscillation circuit and frequency divider circuit is operated with a constant voltage source or constant current source, or the system uses a dynamic frequency divider circuit in the front stage of the frequency divider circuit. In addition, the operation delay time of the frequency divider circuit has increased significantly, and this delay time has caused disadvantages such as the logic adjustment function not working properly or the number of stages of variable frequency division being limited to avoid this. It's coming.

In this way, since the F@F circuit circuits -1 to F4 and the F-F circuit F5 are reset at different timings, the operation delay time of the circuit when performing logical adjustment is the same as that of the F@F circuits F1 to F4. The delay time becomes the main factor, and the F-F circuit F1-l? '5iF-F circuit I+'1~F that must be considered in conventional circuits that are set at the same timing
Since the delay time is shorter than that in 5, there is no restriction on the number of stages for variable frequency variation. For example, although not shown as an example,
