Ag8000

Low cost Power over Ethernet (PoE) solution for the PD (Powered Device)

Silver Telecom has announced the launch of Ag8000, their latest range of low cost PoE modules.

Focusing on low cost applications Ag8000 is ideal for any ethernet peripheral up to 12W,
such as IP phones and gateways, wireless access points, web cameras and security cameras,
door entry systems, RFID tag readers, security systems (PIR, fire detectors, etc), network
drives, Bluetooth access points and media servers.

The device is a fully self-contained 10-pin device, providing a non-isolated DC-DC converter
with signature recognition compliant to IEEE 802.3af. Available with outputs of 3.3V, 5.0V or
12.0V, the Ag8000 require s only one external decoupling capacitor. The combination of
features and packaging provides extremely efficient use of board area, saving significant
system size and cost, and minimising time to market.

This new product contains an IEEE802.3af compliant signature circuit; 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, which takes the 48V, fed by the PSE via
the Cat5 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. It is
also pin compatible with the established Ag9000 range of isolated PoE modules.

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, so that the range covers any
output from 2.5V to 13V. Ag8000 makes up to 12W of power available to the powered device.

Forthcoming variants include high efficiency, and SMT packages. High power options are
currently in development.

Production volumes of the Ag8000 series are now available. For further information, please
contact Silver Telecom or their local representative.
