Switchtec™ PFX PCIe Gen 5 high performance switches double the data rate of PCIe Gen 4.0, while delivering ultra-low latency and advanced diagnostics

To meet the demands of applications such as data analytics, autonomous-driving and medical diagnostics that are driving extraordinary demands for machine learning and hyperscale compute infrastructure, Microchip Technology has announced the first PCI Express (PCIe) 5.0 switches. The Switchtec PFX PCIe 5.0 family doubles the interconnect performance for dense compute, high speed networking and NVM Express® (NVMe®) storage. Together with the XpressConnect™ retimers, Microchip is the industry’s only supplier of both PCIe Gen 5 switches and PCIe Gen 5 retimer products, delivering a complete portfolio of PCIe Gen 5 infrastructure products with proven interoperability.

“Accelerators, graphic processing units (GPUs), central processing units (CPUs) and high-speed network adapters continue to drive the need for higher performance PCIe infrastructure. Microchip’s introduction of the world’s first PCIe 5.0 switch doubles the PCIe Gen 4 interconnect link rates to 32 GT/s to support the most demanding next-generation machine learning platforms,” said Andrew Dieckmann, associate vice president of marketing and applications engineering for Microchip’s data center solutions business unit. “Coupled with our XpressConnect family of PCIe 5.0 and Compute Express Link™ (CXL™) 1.1/2.0 retimers, Microchip offers the industry’s broadest portfolio of PCIe Gen 5 infrastructure solutions with the lowest latency and end-to-end interoperability.”
