The SPoE Interface from an EMC Perspective
Explore the electromagnetic compatibility (EMC) challenges and solutions of the Single-pair Power over Ethernet (SPoE) interface in our comprehensive App Note, "The SPoE Interface from an EMC Perspective." With growing data and power needs in fields like industrial automation, automotive systems, and IoT networks, SPoE offers an efficient solution, enabling both data and power transmission through a single pair of twisted wires. This App Note delves into the EMC performance of our SPoE Reference Design (RD041), focusing on its low emissions and high immunity to continuous and transient interference.
Key findings highlight how the Reference Design meets residential and industrial EMC standards, achieving reliable data integrity and system resilience. The testing in the EMC-Laboratory assesses radiated and conducted emissions, while immunity tests show the ability to maintain function under high-stress interference conditions. With insights into cable shielding effects, performance criteria, and transient resilience, this App Note is an essential guide for engineers and designers looking to implement compact, cost-effective, and robust SPoE solutions in environments where space, reliability, and EMC compliance are critical.
