Overview
The SN65MLVD082DGGG4, produced by Texas Instruments, is an 8-channel half-duplex Multipoint-Low-Voltage Differential (M-LVDS) line transceiver. This device is designed to transmit and receive M-LVDS signals in compliance with the TIA/EIA-899 standard, supporting signaling rates up to 250 Mbps and clock frequencies up to 125 MHz. It is optimized for multipoint data and clock transmission via backplanes and cables, offering a low-power, high-speed alternative to TIA/EIA-485 interfaces.
