Overview
The SN65LVDT41QPWREP is a high-speed, low-voltage differential signaling (LVDS) interface extender chip produced by Texas Instruments. This component is designed to extend the reach of LVDS signals in applications requiring long interconnects, such as those found in Memory Stick™ and MultiMediaCard™ (MMC) interfaces. The SN65LVDT41 combines four LVDS line drivers with a single terminated LVDS line receiver, making it ideal for use at the host end of LVDS-based interface extensions.
