In high-speed PCB designs, with faster edge transitions, tighter trace spacing, and lower noise margins, crosstalk can seriously affect signal integrity. It can distort the victim signal\u2019s amplitude, timing, or edge shape, leading to data errors, jitter, or false switching.<\/p><p>For this reason, controlling crosstalk is no longer optional; it is a core PCB engineering requirement. In this article, we explore the main causes of crosstalk and share practical strategies to reduce it, helping engineers achieve reliable, high-performance
