5.5.3.6. 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. You can statically adjust the VOD of the differential signal by changing the VOD settings in the Quartus® Prime software Assignment Editor.
Figure 83. Differential VOD This figure shows the VOD of the differential LVDS output.
