The device is used in Ethernet switches and Midspans to enable network devices to share power and data over the same cable. PD69008 device is an 8-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 PD69008 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 PD69008 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 80 79 78 77 76 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 Vport_pos0 Vport_pos1 Vport_pos2...
