Silvertel specialises in the design and development of power modules and advanced telecom interface solutions. These solutions include Power over Ethernet modules supporting applications up to 200W. Smart Lighting modules combining PoE with LED driver functionality.



Ag9900 is now the smallest PoE module in the world, superseding the Ag9800. The three versions offered:-

M – standard IEEE802.3af compliant surface mount module;

MT – standard + Industrial temperature surface mount module;

LP – same PoE standard with Low profile (less than 8mm high).

It is designed such that adding just two diode bridges and an electrolytic capacitor to this truly tiny module is enough to enable PoE functionality in a product. Ag9900 is fully compliant to the IEEE 802.3af PoE standard. It provides a PoE signature, classification, isolation and DC to DC conversion options for 12V, 5V, 24V or 3.3V, while taking up minimal PCB space. It is ideal for space constrained PoE applications such as IP phones, wall mount appliances, IP cameras, thermostats, smoke detectors and room sensors, and is perfect for a whole range of new IoT and building automation sensors and devices.

Evaluation Kits

These are a range of evaluation boards for testing and evaluation of Silvertels ultra-miniature IEEE802.3af Ag9900M 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 the Ag6100 (and complementary Ag7100) and Ag6400 PSE modules. It can be ordered as one of eight options, dependent on the module/output voltage variant fitted, from either Ag9924M, Ag9912M, Ag9905M or Ag9903M or with additional over-temperature protection fitted, with the MT suffix.

The Ag9900 Power-over-Ethernet (PoE) modules are the smallest POE solution in the world and designed to extract power from a conventional twisted-pair Category 5 Ethernet cable, conforming to the IEEE 802.3af PoE standard. The Ag9900 signature and control circuit provides the PoE compatibility signature required by the Power Sourcing Equipment (PSE) before applying up to 15W power to the port. The Ag9900 provides a Class 0 signature. The DC/DC converter operates over a wide input voltage range and provides a regulated output. The DC/DC converter also has built-in short-circuit output protection
