5.6.6. Programmable Differential Output Voltage6.3.4. 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 Intel® Quartus® Prime software Assignment Editor.
