Designed for any Ethernet peripheral up to 12WSilver Telecom launched its IEEE 802.3af-compliant Ag9000 series of Power-over-Ethernet (PoE) modules that is designed 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, network drives, Bluetooth access points and video servers.

The Ag9000 is a fully self-contained 10-pin SIL (single-in-line) device, providing an isolated dc-dc converter with signature recognition compliant to IEEE 802.3af. Available with outputs of 3.3-, 5- or 12V, this new module requires just one external capacitor. The combination of features and packaging offers extremely efficient use of board area, saving significant system size and cost, minimizing time to market for developers of Ethernet peripherals, said the company.

Silver Telecom has developed a device that contains the signature recognition circuitry listed in IEEE 802.3af, which 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 1,500V 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.

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 percent. The Ag9000 makes up to 12W of power available to the powered device.

Production volumes of the Ag9000 series are already available.
