3.3V LVDS Driver Termination
A general LVDS interface is shown in Figure 2. 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.
