As embedded applications continue to demand higher bandwidth, lower latency, and superior scalability, PCIe has become a key interface, offering predictability, reliability, and backward compatibility across industrial, automotive, communications, and computing platforms. Unlike data center deployments, embedded designs must balance performance improvements with long-term stability, space constraints, and cost sensitivity. However, integrating PCIe into embedded designs presents challenges related to signal integrity, power management, clocking architecture, layout, and connector selection.
Eight experts' opinions on PCIe for new embedded systems analyze these issues in detail and offer practical, expert advice to ensure a reliable PCIe implementation. The ebook reviews the evolution of PCIe, from the established designs of PCIe 4.0 to PCIe 5.0, 6.0, and 7.0, and examines advancements in input/output and peripheral connectivity, signal integrity, timing architectures, routing, and high-speed interconnects, and how all of these factors influence system-level design.
Based on contributions from Microchip and Samtec, the chapters demonstrate how high-performance PCIe controllers and switches, clock devices, and interconnects are used in embedded architectures, including ways to scale to AI and edge workloads while maintaining predictable latency and long-term stability. The technologies discussed are available in Mouser and are well-suited for embedded designs that require performance, scalability, and reliability.
