Description
The Ag9900 Product Series are the smallest PoE module solutions in the world, measuring as small as 21mm(L)x14mm(W)x8mm(H), and are available in MTB and LPB (Low-Profile) options.
The modules are designed such that adding just two diode bridges and an electrolytic capacitor to this miniature module is enough to enable PoE functionality in a product. Ag9900 product series are fully compliant to the IEEE802.3af PoE standard, and they provide a PoE signature, classification, isolation and DC to DC conversion options for 3.3V, 5V, 12V or 24V, while taking up minimal PCB space. They are ideal for space constrained PoE applications such as IP Phones, Wall Mount appliances, IP Cameras, Detectors, Sensors, and are perfect for a whole range of new IoT and Smart Automation Devices.

Ag9900 Evaluation Board
These are a range of evaluation boards for testing and evaluation of Silvertels ultra-miniature IEEE802.3af Ag9900 SMT package PoE PD modules. It is designed to work with Power Sourcing Equipment (PSE) that supplies power over either the spare pair or the data pair. It is fully compatible with Silvertel’s Ag6120 and Ag6130 PSE Modules (and complementary Ag7100 DC/DC Converter). It can be ordered as one of eighteen options, dependent on the module/output voltage variant fitted, from any of: MTB, LPB, M, MT or LP and 3V, 5V, 12V or 24V variants. Please contact your local distributor, or use the Buy Samples button provided below to order boards. The User Manual can also be downloaded below.
Evaluation Boards are supplied pre-loaded with a sample module. Please ensure that you specify which variant you wish populated into the Eval board on request or ideally on your PO.
