The Cyclone 10 GX development kit includes an FMC connector with loads of LVDS lanes, so the LVDS receivers need termination, right? I don't see terminators on the schematic and I don't see that the Cyclone 10 GX can do OCT (on chip termination) for LVDS. I sure can't find this as an option in Quartus Pro! Does this mean there's no way to do the termination on the development board.

Differential termination can be also enabled in Pin Planner. The respective column must be switched on in context menu first.

Cyclone 10 GX LVDS termination, can it do OCT?

Cyclone 10 GX does support On-Chip I/O Termination which you can refer Table 43 from below link on the OCT schemes supported for LVDS I/O.

Furthermore, Figure 78 shows the termination for differential receiver. It also mentioned that you can enable on-chip termination in the Assignment Editor inside Quartus Prime Pro software. For more details, you can refer below link:

    Thanks to both of you. It makes sense, I just didn't stumble across anything when searching through the help.
