In video electronics, people use a LM1881 chip to get sync from a composite video signal. It's an 8-leg chip that, when provided power, will output a Composite Sync channel when Composite Video is inputted. My question is, instead of inputting Composite Video, you input Sync-on-Luma? (the Y signal in S-Video).
I want to do this because, before the signal hits the chip, the Composite Video is much more prone to noise than Sync-on-Luma, and Sync-on-Luma is available for what I'm doing. Does it have to be Composite Video, or can I use Sync-on-Luma with this chip?
