Modal Crosstalk in High Speed PCB Common Mode to Differential Mode Conversion
In high-speed PCB design, modal crosstalk in high speed PCB—specifically common mode to differential mode conversion—is a critical signal integrity challenge. This mechanism degrades differential signaling performance by converting unwanted common-mode noise into differential-mode errors. Understanding this conversion is essential for engineers designing boards for 10 Gbps+ SerDes, DDR5, or PCIe Gen 5/6. Fundamentals of…
