Differential signaling conventions are shown in
differential amplitude represents the value of the voltage between the
true and complement signals. Peak-to-peak differential voltage is defined
as 2 × (V
mode voltage is the average of V

Programmable Pre-Emphasis
The programmable pre-emphasis module controls the output driver to
boost the high frequency components, and compensate for losses in the
transmission medium, as shown in
statically using the ALT2GXB megafunction or dynamically through the
dynamic reconfiguration controller.
