Branched to a new discussion

The CRC frame-checking block on the ADV7850 is of particular interest to me. The application note AN-1277 [PDF] describes this feature in detail, but the datasheet [PDF] omits it. Is there a newer version of the datasheet?

2.       Can the CRC block be configured over HDMI DDC, or must this be done using the dedicated I²C interface?

3.       What other ADI parts provide the CRC feature? Is there one on the roadmap with HDMI 2.0 support?

4.       Can the ADV7850 be powered solely by the HDMI 5-V line, given the maximum of 500 mA? I won’t be using the analog video inputs or audio, and it may be acceptable to limit the HDMI ports to one input and no output.
