The device is used in Ethernet switches and Midspans to enable network devices to share power and data over the same cable. PD69012 device is a 12-port, mixed-signal, highvoltage Power over Ethernet driver. It enables detection of IEEE802.3af-2003 pliant PDs (Powered Devices) and IEEE802.3AT High Power Devices, thus, ensuring safe power feeding and disconnection of ports. With full digital control via a serial munication interface and a minimum of external ponents, the device integrates into multiport and highly populated Ethernet switches and routers. The PD69012 executes all real time functions as specified in the IEEE802.3af-2003 (“AF”) standard and IEEE802.3at High Power (“AT”) functionality, including load detection, “AF” and “AT” classification and port status monitoring. In addition it performs system level activities such as: power management and MIB support for system management. The Po E device is designed to detect and disable disconnected ports utilizing both DC and AC disconnection methods, as specified in the IEEE 802.3af-2003 standard. The PD69012 is designed to support 2 main configurations: - Auto mode: For Basic ”AF” and “AT” PSE equipment - Enhanced mode: For High End, Extended Features set of AF and AT PSE equipment Pin Configuration _____________ Port_neg5 port_sense5 gate_5 gate_4 port_sense4 Port_neg4 Port_neg3 port_sense3 gate_3 gate_2 port_sense2 Port_neg2 Port_neg1 port_sense1 gate_1 gate_0 port_sense0 Port_neg0 Agnd2 Sense_Neg Vport_pos0...
