This classroom covers Single-Pair (SPE) advancements along with Power over Data Line (PoDL) integration, the role of inductors in SPE in the context of signal integrity and power delivery, and the evolving SPE standards.

SPE with PoDL, as well as dedicated inductors, are enabling forces behind streamlined and efficient connectivity. Engineers faced with complex designs in diverse applications can optimize overall system performance using these technologies that offer higher date rates, enhanced power delivery, and standardized protocols.
