Data Link Layer Classification

The Ag9330 Power-over-Ethernet (PoE) module is designed to extract power from a conventional twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3at PoE standard. With two additional auxiliary inputs, one for an auxiliary DC supply and the other for an auxiliary AC supply. This module is ideal for security cameras where 12Vdc or 24Vac is used. The Ag9330 has been designed to extract power from Power Sourcing Equipment (PSE) over a conventional twisted pair Category 5 Ethernet cable. The modules input conform to the IEEE803.2at standard for signature recognition and class programming. The high-efficiency DC/DC converter operates over a wide input voltage range with a low ripple and low noise output. The DC/DC converter also has built-in output overload, output short-circuit and over-temperature protection and provides a 1500Vdc (input to output) isolation barrier.
