USB PCB Design Guide: USB 2.0, 3.x, and USB4 Routing Rules for Industrial & High-Speed Applications
USB PCB design remains the most widely adopted wired high-speed interface across consumer electronics, industrial embedded systems, medical devices, and high-performance computing. From legacy USB 2.0 at 480 Mbps to USB 3.x up to 10 Gbps and modern USB4 reaching 40 Gbps with PAM3 modulation, each generation imposes stricter PCB routing and layout constraints. Poor…
