Is LVDS supported on the dedicated clock input of the Cyclone 10 GX 3.3V IO Bank?

I do not see where it says this is not allow (handbook, pin connection guidelines) but Quartus is not presenting LVDS as an option. The dedicated clock inputs have always supported LVDS in Altera FP...

my bad...you had that written as GX.

anyway, Cyclone 10 GX does not support 3.3V io bank. Did you mean 3.0V instead?

You are right, LVDS input are powered by VCCPT = 1.8V.

Are you saying that because the bank is powered by 3.0V, you cannot select LVDS as your dedicated clock inputs? when you change the VCCIO to 1.8V, it works? what error do you see? Could you paste the error message here.
