Skyworks Solutions Inc. Si3474-KIT PoE PSE Evaluation Kit

Skyworks Solutions Inc. Si3474-KIT PoE PSE Evaluation Kit is designed to evaluate Si3474 Power Source Equipment (PSE) ICs. These ICs are suitable for use in either a four-port 802.3bt PSE, eight-port 802.at PSE, or a mix of 802.3bt and 802.3at ports. Skyworks Solutions Inc. Si3474 evaluation board includes a four-layer daughter card, a four-layer baseboard, and an RJ45 connector board. This RJ45 interface board called the POE_BT_CB allows the evaluation of the Si3474 in a mixed 802.3bt and 802.3at system. The baseboard consists of status LEDs, terminal blocks for power, USB connector, and AUTO mode selection jumpers.

The Si3474 kit can power up power devices without any software installation. This Si3474-EVB can be jumper-selected (J8) to automatically configure the Si3474 Port Power Allocation (PPA). The Si3474 evaluation kit allows access to the Si3474 registers through a USB interface using the CP2112 USB to I2C bridge. And a Python interface is provided to allow evaluation through Windows PC, Linux, or MacOS computers. The daughtercard is available in 61mm x 61mm size and the baseboard is available in 76mmx 136mm size.
