SPE with PoE: overview, ref design circuit principle, key EMC challenges

This presentation provides a focused insight into the innovative Single Pair Ethernet (SPE) and Power over Ethernet (PoE) technologies, highlighting their fundamental functionalities and critical circuit blocks. SPE and PoE are increasingly vital for modern industrial and automotive applications, simplifying cabling and power delivery. A clear understanding of their internal workings and electromagnetic compatibility (EMC) is essential for robust system design. 

The session will cover: 

• An in-depth understanding of the functionality of SPE/PoE technology, explaining how data and power are transmitted efficiently over a single pair of wires. 
• A detailed explanation of the critical circuit blocks within SPE/PoE systems, outlining their roles and interactions. 
• An outline of key EMC requirements, specifically focusing on immunity to external interference and managing electromagnetic emissions, crucial for reliable operation in challenging environments.
