In the circuit, the D/A converter switches the input data into the voltage, and the voltage is compared with the reference voltage set by the potentiometer, then the output of the comparator is fed back to the reset terminal of the comparator, finally, we get the split pulse. The working method of the circuit is different from that of the feedback splitter of traditional counter, although the traditional way is suitable for solid integer splitting, the constant isn't easy to adjust. This circuit is specially suitable for conditions that need to change the splitting constant in a wide range.
