Hi

 

Attached is script for evaluation boards:

EVAL-ADV7611EB1Z,

EVAL-ADV7611EB2Z,

EVAL-ADV7612EB1Z,

EVAL-ADV7612EB2Z

 

It gets 576i (2x) and outputs as an 656 stream 8-bit to encoder. Encoder outputs it as CVBS.

Same script will work for 480i after changing encoder settings to 480i.

 

Scripts for 656 8/10/12-bit require not only setting appropriate OP_FORMAT_SEL, but also doubling the clock (In red)

Same applies to ADV7619.
