2. Description
The Ag9900 Power-over-Ethernet (PoE) modules are the smallest POE solution in the
world and designed to extract power from a conventional twisted pair Category 5 Ethernet
cable, conforming to the IEEE 802.3af PoE standard.
The Ag9900 signature and control circuit provides the PoE compatibility signature required
by the Power Sourcing Equipment (PSE) before applying up to 15W power to the port. The
Ag9900 provides a Class 0 signature.
The DC/DC converter operates over a wide input voltage range and provides a regulated
output. The DC/DC converter also has built-in short-circuit output protection.
