[ADV7611] How to output no Hsync/Vsync signals from the pin in the BT.656 (Embedded Sync) 8bit output mode.

Hello,

 

I have a question about ADV7611.

 

When we use ADV7611 as BT.656 (Embedded Sync) 8bit output mode, the IC which receives the 8bit BT.656 does not have to get the Hsync/Vsync from the HS pin/VS pin of the ADV7611.
Even if I set the registers of ADV7611 as the 8bit BT.656 (Embedded Sync) mode (OP_FORMAT_SEL[7:0] = 0x00, 8-bit SDR ITU-656 mode), I can see the Hsync/Vsync signals from the HS pin/VS pin of the ADV7611.

 

Question:
 Is there a method or register setting that ADV7611 does not output the Hsync/Vsync signals from HS/VS pin in the   BT.656 (Embedded Sync) 8bit output mode?
 Is this possible?

 

If this is possible, it's useful for debugging our customer's board. I'll try it.

 

Thank you!
Best regards.
Tamu
