My customer need to configure the ADV7393 to 875i . I couldn't find details on setting it in the documentation.
Is it because the ADV7393 doesn't support 875i?
If yes, what is the alternative?
We don't have any specific scripts to configure the ADV7393 for 875i. There 's no reason why the part can not support 875i. I would start with a close resolution like NTSC or 1080i and tweak it as needed. I am not sure how the luma filter should be set.
Any recommendations where to tweak and what to tweak?
The registers in the data sheet do not provide any details or hints.
Unfortunately not. I'd start with NTSC since it is close to 875i and see how that responds, then I'd move the luma filter. The only other information on 875i in this forum has to do with decoding, not encoding.
My advice would be to use the ADV7123/5 DAC. I would not expect that the encoder has the flexibility to configure for standards no listed in the datasheet.
