WebI am using LMH1981 to separate Sync from G_Sync and CSync signals. In Gs, it works since it has negative going Sync Pulses. 1) But if my CSync input is in CMOS or TTL level Logic (normal Pulse 0 to 2.2V). Since it doesn't have negative sync pulses, Does it work ... WebAug 5, 2024 · The diodes should conduct immediately when the 5v signal is applied, regulating the output signal at constant 1.2v which should be a safe level for 1v logic. If …

WebMay 26, 2024 · For consoles that don't have native CSYNC it means you need to mod or use a sync stripper to extract CSYNC from composite video or luma. The one caveat with using a sync stripper is that the picture will be shifted 5 pixels or so compared to everything else + output at ttl voltage. WebMay 28, 2024 · I’ve checked the board in my console and it looks like the modder wired up using the “CS#” pin – which means Csync TTL. Apparently they should have wired using the “CS75” contact for attenuation. It also looks like the jumper on the board (J1, J2, J3) have not been bridged (these should apparently be bridged for use with PAL consoles). simpatico song bad teacher
