This reference design shows an implementation of a single-pair Ethernet (SPE) communication back end including power over data lines (PoDL). The design uses a Sitara™ AM2434 MCU interfacing an analog front end on one side and a Ethernet physical (PHY) layer on the other. The powerful MCU allows not only forwarding sensor data to the Ethernet, but also for performing data processing on the edge.
