Hello Video Experts,
I'm using an ADV7842 and encountering an anomaly with Vertical Sync output in operation. Some initial conditions include:
- Operating in Autographics Mode
- Non Standard Video Resolution/Frame Size
- Register Setup can be emailed [would prefer not to post].
I'm encountering an issue where an Vertical Sync Output has an additional small pulse within the "low" period of the sync pulse [Have scope photos -- again, would prefer not to post].
I've reviewed setup and think that all of the conditions seem correct to produce an uncorrupted VSync pulse, but I think I'm missing something. I can forward any of the setup information upon contact. Thank you!
