Complete Power over Ethernet (PoE) module for the PD (Powered Device)
[June 22, 2005]

Complete Power over Ethernet (PoE) module for the PD (Powered Device)

Silver Telecom has announced the launch of the IEEE 802.3af compliant Ag9000 series of Power over Ethernet modules.

Ag9000 is ideal for any Ethernet peripheral up to 12W, such as IP phones and gateways, wireless access points, web cameras and security cameras.

The device is a fully self-contained 10-pin SIP (single in line package) device, providing an isolated DC-DC converter with signature recognition compliant to IEEE 802.3af. Available with outputs of 3.3V, 5.0V or 12.0V, the Ag9000 requires just one external capacitor. The combination of features and packaging offers extremely efficient use of board area, saving significant system size and cost, minimising time to market for developers of Ethernet peripherals.

The product also contains the signature recognition circuitry listed in IEEE 802.3af. This ensures that it will inter-operate with any PSE (power sourcing equipment) midspan or endspan that conforms to the same standard. Also included is a DC-DC converter with 1500V input to output isolation, which takes the 48V fed by the PSE via the Category 5 Ethernet cable over either the spare pairs or the signal pairs. It is a complete solution in a single package with emphasis on small size, low cost and ease of use.

Additional features include the ability to program the IEEE 802.3af power classification (default is class 0), and the ability to vary the output voltage by up to ± 10%. Ag9000 makes up to 12W of power available to the powered device.


Forthcoming variants including SMT packages, low cost versions and high power options are currently in development.

Production volumes of the Ag9000 series are now available. For further information, please contact Silver Telecom or their local representative.
