PD69000 96-port HPoE MCU
PD69000 is a ninety-six-port, mixed-signal, Power over Ethernet Microcontroller Unit. Used with the PD69012 and PD69008, it allows the detection of IEEE 802.3af-2003, IEEE802.3at-draft2.0 and pre-standard devices, ensuring safe power feeding and removal over Ethernet ports. It also supports 4-pairs IEEE802.3at devices consuming up to 59W. With full digital control via a serial communication interface and a minimum of external components, the MCU integrates in multi-port and highly populated Ethernet switches.
Features IEEE 802.3af-2003 and IEEE802.3at-draft2.0 Compliant with standard and pre-standard IEEE 802.3af PD's and IEEE802.3at PD's 96-ports standalone PoE control for IEEE802.3af and IEEE802.3at PD's 2-event power classification with bypass option AC disconnect DC disconnect with DC modulation Supports RFC3621 Freedom to power all PoE PD's including Cisco's inline power Highest integration on the market, enabling the lowest real-estate occupation Enables building IEEE802.3at-draft2.0-compliant solutions with no need for additional software Reliable and simple AC disconnect implementation Supports low power devices Enables integration in Managed Switches Architecture I C or UART host interface 7-bit I C address selectability Opto-coupler compatible communication lines Up to 96 ports operating autonomously Up to 768 ports operated on a single power budget
