ADV7623 - Latest SW Manual?

Hi everyone,

 

I recently started working with the ADV7623-P but I feel like there are a lot of missing information in the SW manual (downloaded from ADV7623 Design Support Files). Addresses and/or bits seem to be missing!

 

Here is an example, taken from one of the scripts provided by Analog:

##Scripts HDMI - PCM,For Pixel CLK Less than 70MHz##

:1-0 Port A - Audio Output Port:

[....]

68 00 F0 ; Set HDMI Input Port to A (Enable BG monitoring)

68 01 00 ; Enable clock terminators

68 0D F4 ; ADI Recommended Write <- Bits[7:4] not documented

68 1A 8A ; Unmute audio & enable new compressed audio mute mask bit

68 3D 10 ; ADI Recommended Write <- whole address not documented

68 44 85 ; ADI Recommended Write <- whole address not documented

68 60 88 ; ADI Recommended Write <- whole address not documented

68 61 88 ; ADI Recommended Write <- whole address not documented

68 57 B9 ; ADI Recommended Write <- whole address not documented

[....]

 

Q1: What are these registers? Why those values? I would like to understand every I2C command before sending them.

 

Q2: Are Analog's scripts all it it takes to get basic video (1080p@60?) IN and OUT from the chip?

 

Q3: Would it be possible to get documentation for ALL the (missing) registers?

 

 

I don't have a demo board yet and I would like to make sure that I have all the information I need to work on my project, before actually picking this chip.

 

Thank you in advance.

 

Best regards,

Kevin
