4ms QCD

Quad Clock Distributor (10HP)

Based on:
QCD by 4ms.

BOM:
interactive version (top PCB)
interactive version (bottom PCB)

My own layout of the 4ms QCD. I slightly redesigned the panel controls, there's now an overall pulse width control on the main module (no longer needs an extender, applies to all channels). My division and multiplication ratios also max out at 12, but that still leaves a lot of room for slowing down or speeding up clocks.

I also slightly rewrote the original firmware to make optimal use of my particular design.

Build notes

Note that, since I use 10-pin power headers in all my designs, there is no option to clock this particular design from or into the bus.

My custom firmware is here.
