Differential I/O Termination
8–12:

The Stratix IV device family provides a 100-Ω, on-chip differential termination option
on each differential receiver channel for LVDS standards. On-chip termination saves
board space by eliminating the need to add external resistors on the board. You can
enable on-chip termination in the Quartus II software Assignment Editor.
On-chip differential termination is supported on all row I/O pins and dedicated clock
input pins (CLK[0,2,9,11]). It is not supported for column I/O pins, dedicated clock
input pins (CLK[1,3,8,10]), or the corner PLL clock inputs.
