Do the reference clock input pins have internal DC bias voltage?

I am using Cyclone 10 GX device. The reference clock differential pins are set to be LVDS standard. I hope to use AC coupling and on-chip RD termination. If the pins have an internal DC bias voltage, I will not need to implement on-board bias network.

Thanks.

Hello,

Cyclone 10 GX does not have internal DC bias voltage. You can refer for both of these link as you reference for your design.
