DS80PCI102SQ/NOPB

Signal Buffers, Repeaters, Splitters Overview

The DS80PCI102SQ/NOPB is a single-lane PCI Express repeater designed for data rates of 2.5 Gbps, 5.0 Gbps, and 8.0 Gbps. It integrates equalization and de-emphasis capabilities to extend signal reach in high-speed serial links. The device operates on a single supply voltage and supports transparent management of link training protocols. It is housed in a WQFN-48 package and functions as a redriver to restore signal integrity across PCB traces or cables.
