Low-Latency PCI Express 5.0 and CXL 2.0 Retimers for Cost-Effective and High-Speed Signal Connectivity in Data Center’s

Low-Latency PCI Express (PCIe) 5.0 and Compute Express Link (CXLTM) 1.1/2.0 Retimers

Microchip Technology has introduced low-latency PCI Express (PCIe) 5.0 and Compute Express Link (CXLTM) 1.1/2.0 retimers that can triple the reach of PCIe Gen 5 electrical signal reach without compromising performance or security for demanding PCI Express (PCIe) and Compute Express Link (CXL) applications.


Supporting x1/x2/x4/x8/x16 bifurcation, comprehensive diagnostics features, multiple configuration options, simple management interface, and low power, these remitters reduce the total cost of ownership during design, bring-up, validation, and production. 


With the ultra-low-latency, the XpressConnect retimers can deliver demanding computational workloads in AI, ML, communication systems, and high-performance computing applications. Compared to the PCIe specification, these new retimers can deliver >80% lower latency with a pin-to-pin latency of <10 nanoseconds.


XpressConnect retimers are available in multiple lane count variants of up to 16 lanes of PCIe Gen 5 to connect to a wide range of PCIe and CXL devices. This device can be used in various applications such as motherboard, backplane, cable, and riser card use cases.
