Questions from customer:
1. Where can I find ADV7611, ADV7612 scripts?
2. How can they be modified to accept other video standards? (1080p23, 1080p24, 720p24) ???
1. All scripts are available on EZ.analog websites (Design Support Files):
2. There is really no need to modify scripts. Basic scripts accept wide range of video modes and require no additional modificiation based on vertical frequency or pixel clock frequency. Below is a comparision between 480i...576p, (720p, 1080i) and 1080p on the right. We can see the only difference is in following write:
98 06 A6; Invert VS, HS polarity on output pins.
This write is used to satisfy back-end device requirement and it might be even not needed (deepending on what you are connecting to).
