3.3V LVDS Driver Termination

A general LVDS interface is shown in Figure 3. In a 100

 differential

transmission line environment, LVDS drivers require a matched load

termination of 100

 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.
