Hi,

there is a pin named Vbb in CDCLVD110, and I don't know what it for. Is it for reference voltage used by external chips? If I want to use this chip driving FPGA's LVDS pins, can we ignore this Vbb?

THX!

Hello Donald,
the VBB pin is a reference voltage output. You can find the characteristics in the electrical section. It is intended for usage with the inputs of the device when you AC couple them.
best regards,
Patrick

Thanks!

So you mean if I use DC coupling, I don't need Vbb?

Hello Donald,
when you are sure that your input signals can meet the input specs: yes.
