Design of a Single Pair Ethernet System with Power over Data Lines (SPoE)

Overview

TopologyLAN / POE
IC revision1.6

Description

This reference design note describes a system that cantransmit data between two points via a two-wire line. Themain unit supplies the peripheral unit with power via thesame two-wire line over which the data is transmitted. Thismethod is called "Single Pair Ethernet" with "Power over DataLines".

Features

 Supports multiple power levels of Power overEthernet Detecting and classifying the PD, sourcing the rightamount of power to the PD PoDL class 12 up to 30 V / 8.3 W USB 3.1 port (no power) 10 / 100 Mbit/s Ethernet port 10 Mbit/s SPE port Data transfer between USB 3.1 and 10 / 100 Mbit/sEthernet Data transfer between USB 3.1 and SPE (10 Mbit/s) Data transfer between SPE (10 Mbit/s) and10 / 100 Mbit/s Ethernet
