What's the difference between terminations "LVDS_crin" to "LVDS_crin_t100" ?

Both "LVDS_crin" and "LVDS_crin_t100" OCT are differential terminations.

Asfar as I know, a differential termination is a 100 ohm resistor between P and N. Whose one of the above is 100 ohm termination and what's the difference between them ?

Thanks,

    No. LVDS_crin is LVDS input with termination off. Look at the Ibis file input currents and you'll see.
