Scaling AI Infrastructure: The Critical Role Of PCIe 7.0 Retimers


In a previous blog, Scaling in the AI Era: The Role of PCI Express 7.0 Switches in Next-Gen Data Centers, we explored how PCIe 7.0 switches enable high-bandwidth, low-latency interconnects for AI-driven data centers. Switches are essential for building flexible, composable architectures that connect thousands of GPUs, accelerators, and memory subsystems. But as AI clusters grow in size and comp... » read more

Integrating Ethernet, PCIe, And UCIe For Enhanced Bandwidth And Scalability For AI/HPC Chips


By Madhumita Sanyal and Aparna Tarde Multi-die architectures are becoming a pivotal solution for boosting performance, scalability, and adaptability in contemporary data centers. By breaking down traditional monolithic designs into smaller, either heterogeneous or homogeneous dies (also known as chiplets), engineers can fine-tune each component for specific functions, resulting in notable im... » read more

Essential Insights for Design PCIe 6.0 Interconnects


PCI Express (PCIe) is a serial communication protocol that has progressed through generations to enhance data rates and functionality. The latest version, PCIe 6.0, doubles the data rate to 64 GT/s, enabling up to 256 GB/s of bandwidth in an x16 configuration. The technology incorporates PAM4 signaling and forward error correction to maintain high speeds with improved signal integrity and relia... » read more
