Hi !

 

I have few question about ADV7511W.

One of our customer want to use ADV7511W the camera system.

And they are thinking that insert Common Mode Choke Filter to

TXC-(17),TXC+(18),TX0-(20),TX0+(21),TXC-(23),TXC+(24),TX0-(26),TX0+(27)

And at the Eval-board circuit , it has a comment like this.

"ROUTE THESE AS 100 OHM DIFFERENTIAL PAIRS"

So my question is this.

 

1)

With their understanding, the important thing is to make the impedance 100Ohms.

So they gonna find the Common Mode Choke Filter with impedance near the 100Ohms.

Is their understanding correct?

 

2)

And is there any other thing to take care about choosing Common Mode Choke Filter?

If you have some advice about this , can you give me?

 

Best regards.

Kawa
