(1) For interfacing LVDS outputs to CML or LVPECL compatible inputs, refer to the applications section of this datasheet (planned).
(2) The LVDS outputs do not support a multidrop (BLVDS) environment. The LVDS output characteristics of the DS15MB200 device have
been optimized for point-to-point backplane and cable applications.
