Product Introduction

Overview

The DS90LV804TSQ/NOPB is a high-speed, 4-channel LVDS (Low Voltage Differential Signaling) buffer/repeater produced by Texas Instruments (TI). This device is designed to enhance signal integrity in large systems where signals are distributed across cables, ensuring reliable data transmission at speeds up to 800 Mbps. The DS90LV804TSQ/NOPB features internal input and output terminations, which eliminate the need for external components and improve signal quality, especially over longer cables. It operates from a single 3.3V supply and is packaged in a compact WQFN (Leadless Leadframe Package) with 32 pins, making it suitable for various applications requiring high-speed data transmission with low noise and efficient power usage.
