If a design uses external termination, the receiver must be externally
terminated and biased to 0.85 V or 1.2 V.

Programmable Equalizer
The Stratix II GX receivers provide a programmable receive equalization
feature to compensate the effects of channel attenuation for high-speed
signaling. PCB traces carrying these high-speed signals have low-pass
filter characteristics. The impedance mismatch boundaries can also cause
signal degradation. The equalization in the receiver diminishes the lossy
attenuation effects of the PCB at high frequencies.
