Product Information

The Si3454 8-port evaluation kit (Si3454-KIT) is intended for Power over Ethernet (PoE) Power Sourcing Equipment (PSE) system designers interested in evaluating the 4-port Si3454 PSE controller. The Si3454 is controlled through an I2C (or SMBus) interface. For convenience in evaluation, a graphical user interface (GUI) is provided, giving an easy-to-use visual display and control of the Si3454 I2C registers. The evaluation kit assumes the user has access to a PC to control the evaluation board using the provided GUI. The user is also responsible for providing an appropriate high-voltage power supply. The power supply should be 45 to 57 V for normal PoE or 51 to 57 V for PoE+. The Si3454 can supply over 30 W to each port. Thus, the two Si3454 controllers for the 8-port demo system can provide over 240 W of total power. Normally, a 50 to 100 W power supply is used. While the classification and actual current consumption of each port is available, the demo GUI interacts with the Si3454 on a per-port basis and does not implement system-level power management.

Contact Silicon Laboratories for more information about system-level power management options.

The Si3454-KIT kit has been thoroughly tested for standards compliance and interoperability. Contact Silicon Laboratories for test reports using Sifos PoE test equipment and University of New Hampshire PoE standards compliance and interoperability reports.
