(1) Drive strength is programmable according to values in found in the Stratix GX Architecture chapter of the
Stratix GX Device Handbook, Volume 1.
Figures 6–1 through 6–3 show receiver input and transmitter output
waveforms, respectively, for all differential I/O standards (LVDS, 3.3-V
PCML, LVPECL, and HyperTransport technology).
