Just some photos of the clock patch I made myself from the Phantom schematic, I *know* it isn't the prettiest but I was proud of myself :)

Schematic:

Backside of my pcb: Front side of pcb: Connection to DSP line: Connection to SDMA line with capacitor to ground:

Cool.

I actually found the capacitor made things worse.

Looks like the second chip does a inversion.. 40ns delay at 25mhz.. but with the delays of the chip, its probably more like a buffer..

Also ctirad recommended for me to add these extra capacitors to my clock patch, but for some reason the Falcon wouldn't boot afterwards. Still, I took a photo for my records. I had to remove the capacitors afterwards. I think I remember him saying it was strange, apparently it should have just smoothed out the voltage a bit more.
