Overview
The SN65LVDM176D is a high-speed differential line transceiver produced by Texas Instruments. This device is configured as a transceiver that utilizes low-voltage differential signaling (LVDS) to achieve signaling rates as high as 400 Mbit/s. It is designed for half-duplex or multiplex baseband data transmission over controlled impedance media, such as printed-circuit board traces, backplanes, or cables. The SN65LVDM176D is similar to TIA/EIA-644 standard compliant devices but with doubled output current, allowing for double-terminated lines and enhanced performance.
