You don't need to connect differential termination to see specified LVDS voltage range. Unterminated pins simply swing to VCCIO and GND for 1 and 0 state. In so far termination isn't required to see LVDS output working. There must be another elementary problem in your test, e.g. probing wrong FMC pins.

So, I don't need an LVDS IP ?
