Hello,

My customer use ADV7610 in their system.

And the block of their system is like below and for more detailed things, please refer attached their schematic"HDMITOSDI_REV01.pdf".

 

"HDMI"  Input --> ADV7610 --> MDIN325 (Video Scaler) --> GV7600 (Video Transmitter) --> Output "SDI"

 

In this system, MDIN325 only do a Color Conversion, not Resolution Conversion.

 

But they got some issues at their SDI output.

When they confirm the SDI output using SDI Monitor, they can see strange opuput screen like attached picture "20150820_104036.jpg".

 

So they need your help for fixing Issue.

 

Q1) Would you confirm their register setting values in attached file " Register values of ADV7610.txt"?

 

Q2) Would you confirm attached their schematic?

 

Q3) Would you advise how to fix this issue?

 

Please advise me.

(Unfortunately, they don't have ADV7610 EVM.)

If you have any questions, please let me know.

 

Regards,

Se-woong
