SN65LVDS109: Are external termination resistors required across the LVDS receiver input pins (1A &1B), (2A & 2B)?

The question is basically fully stated in the title, the datasheet did not mention that external termination resistors where required, nor did it mention if termination resistors are included inside the enclosure.

    This device does not have integrated termination resistors (this would have been mentioned).

    Termination resistors are not strictly necessary, but if you do not have termination that matches the characteristic impedance of the cable, reflections will cause ringing.
