3.3V LVDS Driver Termination
A general LVDS interface is shown in Figure 3. In a 100Ω differential
transmission line environment, LVDS drivers require a matched load
termination of 100Ω across near the receiver input. For a multiple
LVDS outputs buffer, if only partial outputs are used, it is
recommended to terminate the unused outputs.
