Design of a Single Pair Ethernet System with Power over Data Lines (SPoE)
Overview
| Topology | LAN / POE |
| IC revision | 1.6 |
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
