RECOMMENDATIONS FOR UNUSED OUTPUT PINS
OUTPUTS:
LVDS Output
All unused LVDS outputs can be left floating. We recommend
that there is no trace attached. Both sides of the differential
output pair should either be left floating or terminated.
2.5V LVDS DRIVER TERMINATION

transmission line environment. For buffer with multiple LDVS driver,
it is recommended to terminate the unused outputs.
