2 M-LVDS Standard Overview

The M-LVDS standard specifies electrical characteristic of line drivers and receivers intended for general data transport over a multipoint bus (Figure 2-1) where up to 32 nodes may be connected. More specifically, it defines driver output characteristics, and input characteristics of two receiver types. The following two sections summarize the key M-LVDS driver and receiver characteristics and compare them to the characteristics of drivers and receivers conforming to the two other popular differential standards: RS-485 (TIA/EIA-485-A) and LVDS (TIA/EIA-644-A).
