Nintendo SNES SHVC-CPU-01 Clock Buffer
Design done in Kicad 5.1.10 with Digikey libraries. If you want to edit it, you'll need those libraries as well as these files.
The purpose of this board is to fix FXPak/SD2SNES issues with SHVC-CPU-01-based SNES consoles. The original clock driver on these PCB's is extremely load sensitive.
Tested working, this workaround solves the glitches with the aforementioned cart(s).
Installation instructions done, along with a pre and post-mod MCK trace waveform image. (10/30/21)
Forgot to note - you'll want to have these made as the 2oz/0.8mm PCB's if using OshPark, so the castellations come out correctly. https://oshpark.com/shared_projects/jDfGjfv4 - Direct shared link @ OshPark
