Electromagnetic interference (EMI) is an issue every designer of Ethernet-connected devices has to deal with. Making sure the devices are compliant with or meet the requirements of electromagnetic compatibility (EMC), the process of keeping EMI under control so other nearby devices are not impacted, can be frustrating.
While simulation modeling and other design tools will help achieve 90% of EMC goals, the following additional steps are required to complete the final 10%.
Complete the printed circuit board (PCB) layout.
Components are fully populated on the PCB and…
