Overview
The SN65MLVD201DR, produced by Texas Instruments, is a multipoint-low-voltage differential (M-LVDS) line driver and receiver. This half-duplex transceiver is designed to operate at signaling rates up to 200 Mbps and complies with the M-LVDS standard TIA/EIA-899 for multipoint data interchange. It is optimized for use in multipoint bus applications, offering features such as controlled driver output voltage transition times for improved signal quality and a wide common-mode voltage range to handle significant ground noise.
