Hi !

 

I have a question about ADV739x.

Our customer are using ADV739x with separated sync.

But the input range is 16-235 SD.

 

So my question is this.

 

1)

Is there any resister to change the input range to Full-range or Limited-Range when the customer are using SD input?

Is it this resister?

If we set 0x30[1:0] to 2'b11 would it be Full-Range?

But this is for ED/HD so if our customer are using SD, I think this is not the resister to change the range.

Or is there no way to use Limited-range with separate  sync?

 

2)

If we use ADV739x with Embedded sync, can ADV739x output 100% white(100IRE)?

I mean if the input code is 235 , can ADV739x output 100% white?

 

Best regards.

Kawa
