Hey all -
I built a
Cirrus Logic CS8406 circuit for an old game console (Sega Saturn) using
this, and I seem to be getting an odd signal on the output. The frequency should remain constant (I assume), but the output is rather noisy - looks like a ghost of the signal can be seen, and the frequency seems like it is 170 kHz ...but it will spike to 250 or 350 on my scope. At the moment i snapped the attached scope photo, the freq registered 340 kHz.
Can any of you guys recommend some common issues (Ground specifics, wire length/gauge, noisy clock, etc.) that tend to cause an issue like this?
Thanks!
