Overview
The SN65MLVD206B is a multipoint-low-voltage differential signaling (M-LVDS) line driver and receiver produced by Texas Instruments. This device is optimized to operate at signaling rates up to 200 Mbps and complies with the M-LVDS standard TIA/EIA-899. It is designed for demanding industrial applications, offering robust performance and high signal integrity. The SN65MLVD206B operates from a single 3.3-V supply and features a Type-2 receiver that can detect bus states with as little as 50 mV of differential input voltage over a common-mode voltage range of –1 V to 3.4 V. The device also includes on-chip ESD protection against ±8-kV human body model (HBM) and ±8-kV IEC 61000-4-2 contact discharge.
