3.3V, 2.5V 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
un-used outputs.
