PoE全称为Power Over Ethernet，是指通过10BASE-T、100BASE-TX、1000BASE-T以太网网络供电，其可靠供电的距离最长为100米。通过这种方式，可以有效的解决IP电话、无线AP、便携设备充电器、刷卡机、摄像头、数据采集等终端的集中式电源供电，对于这些终端而言不再需要考虑其室内电源系统布线的问题，在接入网络的同时就可以实现对设备的供电。
The DM9161B is a physical layer, single-chip, and low power transceiver for 100BASE-TX and 10BASE-T operations. On the media side, it provides a direct interface either to Unshielded Twisted Pair Category 5 Cable (UTP5) for 100BASE-TX Fast Ethernet,
The DM9331A is a physical-layer, single-chip, low power transceiver for media converter application. On the media side, it provides a direct interface either to Unshielded Twisted Pair Category 5 Cable (UTP5) for 100BASE-TX Fast Ethernet, and it als
Abstract: Support for optionally powering a 10BASE-T, 100BASE-TX or 1000BASE-T DTE device via the Power Interface (PI) using physical layers defined in Clauses 14, 25, and 40. The Power Sourcing Equipment (PSE) is located at an endpoint or midspan,
100Base-T1 与100Base-Tx 快速以太网转换器，内置NXP PHY. 用于车载以太网芯片调试，模块测试，仿真等； The 100BASE-T1 MediaConverter_NXP establishes one direct point-to-point conversion between automotive ECU’s using 100BASE-T1 and any standard Fast Ethernet device with RJ-45 connector.
