Overview
The SN65LVDM176DGKR is a high-speed differential line transceiver produced by Texas Instruments. This device is configured as a transceiver that uses low-voltage differential signaling (LVDS) to achieve signaling rates as high as 400 Mbit/s. It is designed for half-duplex operation and is compliant with the TIA/EIA-644 standard, with modifications to double the output current of the drivers. This allows for double-terminated lines and enhances the signal integrity over controlled impedance media.
