To drive inputs higher than V
LVTTL and LVCMOS input levels to overdrive input buffer option in the Quartus II software.
These pins support SSTL-18 class II and 1.8- and 1.5-V HSTL class II inputs.
PCI-X does not meet the IV curve requirement at the linear region. PCI-clamp diode is not available on top and
bottom I/O pins.
Pseudo-differential HSTL and SSTL outputs use two single-ended outputs with the second output programmed
as inverted. Pseudo-differential HSTL and SSTL inputs treat differential inputs as two single-ended HSTL and
SSTL inputs and only decode one of them.
This I/O standard is not supported on these I/O pins.
This I/O standard is only supported on the dedicated clock pins.
PLL_OUT does not support differential SSTL-18 class II and differential 1.8 and 1.5-V HSTL class II.
mini-LVDS and RSDS are only supported on output pins.
LVPECL is only supported on clock inputs.

High-Speed Differential Interfaces
Cyclone II devices can transmit and receive data through LVDS signals at
a data rate of up to 640 Mbps and 805 Mbps, respectively. For the LVDS
transmitter and receiver, the Cyclone II device’s input and output pins
support serialization and deserialization through internal logic.
