PD70100/PD70200 IEEE® 802.3af/at PD Front End IC Product Overview The PD70100 and PD70200 devices are part of Microchip’s series of Power over Ethernet (PoE) Powered Devices chips (PD). The PD70100 and PD70200 devices transmit integrated power and analog data in a single 12-pin package. They are used in Powered Devices (PD), thus enabling next generation network devices to share power and data over the same cable. Microchip’s PD family offers a solution to any PD application compliant with IEEE® 802.3af and IEEE 802.3at standards and 4-pairs extra power applications. The IC family’s components can be used in both indoor and outdoor applications.
