DS25BR120: LVDS Input common mode voltage when ac coupling

Kazuhiko Hirano

Part Number: DS25BR120

Hello,

My customer would like to connect differential LVDS output to DS25BR120 IN+/IN- with ac coupling like Figure 5 in the datasheet. In this case, how much is the IN+/IN- common dc voltage?

Best regards,

Please see this app note, https://www.ti.com/lit/an/slaa840/slaa840.pdf. You need to provide external common mode voltage. Please also note that the data must be DC balanced when using AC coupling on the LVDS input.

Thanks

David
