Reflection in Transmission Line for Differential Pairs Common Mode vs Differential Mode
In high-speed PCB design, managing signal integrity (SI) is paramount, especially for differential pairs used in protocols like USB, HDMI, PCIe, and Ethernet. One of the most critical yet often misunderstood phenomena is reflection in transmission lines, specifically the distinction between common mode and differential mode. While differential signaling inherently offers noise immunity, reflections can…
