1 / 19 page  PD64004AH - 4-Port Power Sourcing Equipment Manager for Power over Ethernet Systems Description Applicable Documents Key Features Microsemi’s™ PD64004AH is a 4-port, mixed-signal, high-voltage Power over Ethernet (PoE) Manager designed to support IEEE 802.3af-2003 and 802.3at- 2009 PoE applications. PD64004AH is used in Ethernet switches (endspans) and midspans to enable next generation network managers to share power and data over the same cable. With full digital control via a serial communication interface and a minimum of external components, the PD64004AH can be placed in multi-port and highly populated Ethernet switches. PD64004AH integrates power, analog and logic functions in a single 48-pin, QFN-PS package allowing compact designs. The PD64004AH detects IEEE 802.3af- 2003 compliant Powered Devices (PDs) and 802.3at-2009 PDs which exceed IEEE802.3af power levels, ensuring safe power feeding and port disconnection. The PD64004AH executes all real time functions as specified in the IEEE 802.3af- 2003 standard and the IEEE802.3at-2009 standard including detection, 1-event classification and port status monitoring. It also executes system level activities such as power management, and MIB support for system management. The PD64004AH is designed to detect and disable disconnected ports, using both DC and AC disconnection methods, as defined in IEEE 802.3af-2003 and IEEE802.3at-2009. The PD64004AH, in conjunction with the PD63000G or in Automatic mode, can be configured to support 2-pair 802.3at-2009 (up to 600 mA.) and 2-pair standard “af” power (up to 350mA) for full IEEE802.3af compliant functionality. Further, in AF mode the PD64004AH and PD63000G can support 8-ports operation (when working together, the units are in Enhanced mode). Performance of the PD64004AH can be fully evaluated using the PD-IM-7316AH evaluation board.
