Overview
The SN65LVDT390PW is a high-speed differential line receiver produced by Texas Instruments. This component is part of a family of 4-, 8-, or 16-differential line receivers that implement the electrical characteristics of low-voltage differential signaling (LVDS). The LVDS technique reduces power consumption, increases switching speeds, and allows operation with a 3-V supply rail, making it suitable for high-speed data transmission applications.

Applications
The SN65LVDT390PW is intended for point-to-point baseband data transmission over controlled impedance media of approximately 100 Ω, such as printed-circuit board traces, backplanes, or cables. It is particularly useful in synchronous parallel data transfers, allowing precise timing alignment of clock and data signals. When used with its companion drivers (SN65LVDS389 or SN65LVDS387), it can achieve over 200 million data transfers per second in single-edge clocked systems with minimal power consumption.
