Differential I/O standards typically require a termination resistor between the two
signals at the receiver. The termination resistor must match the differential load
impedance of the bus
The Cyclone III device family supports differential SSTL-2 and SSTL-18, differential
HSTL-18, HSTL-15, and HSTL-12, PPDS, LVDS, RSDS, mini-LVDS, and differential
LVPECL.
