The EP2C35 Nios II board as shipped has no I/Os suited for LVDS usage. The proto and PMC expansions signals have level converters for 5 V tolerance and are fixed to 3.3V VCCIO. Only the mictor connector signals are basically prepared to be used for LVDS. But VCCIO8 has to be changed to 2.5V by a solder jumper, also termination resistors must be possibly added to the board. See the board schematic for details.
