How to avoid later modifications in the early design of a power line carrier PLC?

To avoid EMC rework in power line carrier PLCs, EMC design must be integrated from the outset. Establish EMC design specifications in the early stages, including PCB stack-up, layout partitioning, and grounding strategies. Select proven EMC components, such as the common-mode inductor CML4532A-510T and TVS diode SMCJ24CA. Use simulation tools to perform SI/PI/EMC simulations to predict potential problems. Conduct prototype pre-testing to identify and resolve issues early. Establish a design review process and invite EMC experts to participate. Thorough early design can reduce rework costs by over 90% and shorten the development cycle.
