Product Introduction

Overview

The DS80PCI402SQE/NOPB, produced by Texas Instruments, is a 2.5-Gbps, 5.0-Gbps, and 8.0-Gbps 4-lane PCI Express repeater designed to enhance the reach of PCI Express serial links in various interconnect scenarios. This device is part of a comprehensive family of PCI Express repeaters, offering proven system interoperability and automatic rate detection and adaptation to Gen-1, Gen-2, and Gen-3 data rates. It is ideal for x4 (or lower) PCI Express configurations and supports longer distance transmission in lossy copper cables and backplanes.
