I'm looking to buffer CSYNC coming from arcade boards with a Schmitt trigger. I'm doing some experiments with a 74AHCT1G17 (single Schmitt trigger buffer) followed by a voltage divider.
I've tried different boards and I get a stable ~350mV output. They work perfectly, that's very nice... but unfortunately it doesn't work with Neo Geo MVS. This is the only board that doesn't sync, getting no signal at the output of the buffer. I've read about Neo Geo having an ugly clock signal but I'm not sure if that's the cause, or what should I look for to make this work properly.
Any suggestion or idea is most welcome.
