Using Differential Outputs
Differential input signals do not require any special voltage. LVDS and RSDS differential
outputs signals, on the other hand, require a 2.5V supply on I/O Bank 0. The board
provides the option to power I/O Bank 0 with either 3.3V or 2.5V.
highlights the location of jumper JP9.
If using differential outputs on the FX2 connector, set jumper JP9 to 2.5V. If the jumper is
not set correctly, the outputs switch correctly but the signal levels are out of specification.

I/O standards. These header connections are shared with the 6-pin accessory headers, as
