Overview
The SN65LVDM31D is a high-speed differential line driver produced by Texas Instruments. This device incorporates four differential line drivers that implement the electrical characteristics of low-voltage differential signaling (LVDS). It is designed to operate with a single 3.3-V supply and is suitable for both point-to-point and multiplexed baseband data transmission over controlled impedance media such as printed-circuit board traces, backplanes, or cables.
