Yves Usson's Clock Divider

Yves Usson's Clock Divider

Easy-to-build synchronization source for up to three devices with the ability to divide the main clock



Bill of materials


The module can be used as a synchronization source for step sequencing or for triggering events. It provides a way to synchronize up to three step sequencers with different frequencies from one external main clock generator, and the main clock cycle can be divided into 1 (no change), 2, 3, 4, 5, 6, 7 or 8 independently of each other.

Three dividers can be synchronized with the same clock signal at input No. 1, but for the second and third dividers different main clock pulses can be used by connecting them to inputs 2 and 3. Split clock signals are available at outputs 1, 2 and No. 3 with status display using LEDs. All outputs have the same pulse width as external clock pulses.

To synchronize dividers is intended to input "Reset".
