Device Overview

Summary

XpressConnect™ Retimers provide best-in-class signal conditioning for PCI Express® 5.0 and Compute Express Link™ 1.1/2.0 interconnects and support Intel's® PCIe 5.0 Retimer Supplemental Features and Standard BGA Footprint specification. XpressConnect Retimers triple the reach of PCIe Gen 5 electrical signals with minimal impact to latency to enable the most demanding computational workloads in artificial intelligence, machine learning, communication systems and high-performance computing applications.

XpressConnect Retimers support x1/x2/x4/x8/x16 bifurcation to connect to a wide range of PCIe and CXL devices. XpressConnect Retimers delivers the industry's lowest latency retimer solution with over 80% lower latency than the PCIe specification to maximize performance for PCIe and CXL devices. XpressConnect Retimers includes comprehensive diagnostics features, multiple configuration options, a simple management interface and low power to reduce total cost of ownership during design, bring-up, validation and production.

XpressConnect Retimers are ideal for enterprise servers, PCIe NVMe enclosures, all Flash NVMe arrays, PCIe fabrics, CXL accelerator/memory solutions, and other applications that require low latency, low power and secure PCIe and CXL retiming.
