ADV7511: AVI Infoframe setting for 1920 x 384 59.94Hz

Hi all,

We develop and sell boards using Xilinx MPSoC and ADV7511.

We are investigating the settings of the ADV7511 for a 1920 x 384 size HDMI output receiving customer's request who purchased board.
We made the settings and confirmed that the HDMI analyzer could output the signal, but We was pointed out that there was no AVI Infoframe data, and We do not know how to set it on the ADV7511. From the programming guide of ADV7511, We think that it is necessary to set the following address properly, but We don't understand which one should We choose.

Address: 0x56

Bits: [5: 4]

Register Name: Picture Aspect Ratio


00 = no data

01 = 4: 3

10 = 16: 9

11 = None

if We need other register setting related AVI InfoFrame, We hope to know the other settings too.

Thank you very much for your help.

Best regards,

Katsumi Yajima
