Overview
The SN65LVDS100DGK is a high-speed differential receiver and driver produced by Texas Instruments. This component is designed to operate as a buffer, repeater, and translator for low-voltage differential signaling (LVDS), positive-emitter-coupled logic (PECL), and current-mode logic (CML) signals. It supports signaling rates up to 2 Gbps and is characterized for operation over a temperature range of –40°C to 85°C. The device is available in an 8-pin VSSOP (DGK) package, making it suitable for various high-speed data transmission applications.
