Differential Pair Routing Rules for High-Speed PCB Design
High-speed PCB design relies heavily on differential pair routing rules to maintain signal integrity, suppress common-mode noise, minimize crosstalk, and reduce EMI radiation. With the rapid upgrade of high-speed interfaces such as PCIe 5.0, USB 4, and 100G-KR4, improper differential layout easily causes impedance discontinuity, signal skew, bit errors, and system instability.
