Simulation of Crosstalk and De-sense in a Mobile phone

This interactive infographic uses short videos to explain the electromagnetic compatibility (EMC) and signal integrity (SI) issues affecting the design of a mobile phone.

USB 3.2 offers data speed up to 20GBit/s. These fast signals create broadband noise that can affect other electronics systems even at radio frequencies (RF). This often leads to RF de-sense and crosstalk.

Electromagnetic simulation can be used to analyze the distribution of currents and electromagnetic fields inside devices, showing how they propagate and identifying the coupling paths that can cause interference issues. With this information, engineers can improve the routing of traces and add interference mitigation components such as via fences.
