Silvertel Ag5305 20 W PoE module for the powered device

Silvertel has announced its IEEE 802.3at compliant Ag5305 PD (powered device) module. Aimed at developers of Ethernet equipment requiring up to 20 W of power, such as IP cameras, PTZ cameras, WiMAX access points, door entry systems, digital signage, and VoIP phones and terminals, the product offers a drop-in IEEE802.3at solution.

The module is a Class 4 PD, which provides up to 20 W of power by displaying the correct class pulses to an IEEE802.3at PSE. A complete high-efficiency DC-DC converter is included and generates a nominal 5 V output, which can be programmed down to 4.4 V or up to 5.8 V. Additional features include 1500 V isolation (input to output), as well as overload, short-circuit and thermal protection.

Requiring just a few external components, the product is easy to use and occupies a minimum of PCB real estate. The device supplements Silvertel’s extensive offering of Power over Ethernet products for both the PD and PSE.
