PRELIMINARY

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

Ω differ-

ential transmission line environment, LVDS drivers require a

matched load termination of 100

Ω across near the receiver in-

put. For a multiple LVDS outputs buffer, if only partial outputs

are used, it is recommended to terminate the un-used outputs.

LVDS

All unused LVDS output pairs can be either left floating or

terminated with 100

Ω across. If they are left floating, we

recommend that there is no trace attached.
