Document Table of Contents Programmable Differential Output Voltage

The programmable VOD settings allow you to adjust the output eye opening to optimize the trace length and power consumption. A higher VOD swing improves voltage margins at the receiver end, and a smaller VOD swing reduces power consumption.
Figure 8. Differential VOD This figure shows the VOD of the differential LVDS output.

You can statically adjust the VOD of the differential signal by changing the VOD settings in the Intel® Quartus® Prime software Assignment Editor.
