2. Description
The Ag9800M Power-over-Ethernet (PoE) modules are designed to extract power from a
conventional twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3af PoE
standard.
The Ag9800M 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 Ag9800M 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.
