Cyclone 10 GX LVDS termination, can it do OCT?

[Oliver_I_Sedlacek]

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.

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:

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

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