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

[Twincreeks]

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. 

1. Cyclone 10 GX Device Datasheet: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cyclone-10/c10gx-51002.pdf

2. Cyclone 10 GX GPIO: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cyclone-10/c10gx-51003.pdf

Thank you.
