Pre-emphasis percentage is defined as V
differential emphasized voltage (peak-to-peak) and V
steady-state voltage (peak-to-peak).
Programmable Transmitter Termination
The programmable termination can be statically set in the Quartus II
software. The values are 100 Ω , 120 Ω , 150 Ω , and off.

Receiver Input Buffer
The Stratix GX receiver input buffer supports the 1.5-V PCML I/O
standard at a rate up to 3.1875 Gbps. Additional I/O standards, LVDS,
3.3-V PCML, and LVPECL can be supported when AC coupled. The
common mode of the input buffer is 1.1 V. The receiver can support
Stratix GX-to-Stratix GX DC coupling.
