Analog Devices / Maxim Integrated MAX5996CEVKIT Evaluation Kit
Analog Devices MAX5996CEVKIT Evaluation Kit is a fully assembled and tested surface-mount circuit board featuring an Ethernet port, network-powered device (PD) interface controller circuit for -57V supply rail systems. The Evaluation Kit implements the MAX5996C IEEE® 802.3af/at/bt-compliant network PD interface controller in a 16-pin TQFN package with an exposed pad. Analog Devices MAX5996CEVKIT Evaluation Kit receives power from IEEE 802.3af/at/bt compliant power-sourcing equipment (PSE). The PSE provides the required -36V to -57V DC power over an unshielded twisted-pair Ethernet network cable to the eval kit’s RJ45 magnetic jack. The Analog Devices MAX5996CEVKIT features a 1 x 1 Gigabit RJ45 magnetic jack for separating the DC power provided by an endspan or midspan Ethernet system.
