MAX5996CEVKIT#

MAX5996CEVKIT# is a MAX5996C evaluation kit (EV 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 EV kit uses the MAX5996C IEEE® 802.3af/at/bt-compliant network PD interface controller in a 16-pin TQFN package with an exposed pad. The IC is used in Power-over-Ethernet (PoE) applications requiring DC power from an Ethernet network port for PDs such as VoIP phones, wireless access nodes, security cameras, lighting, and building automation. The EV 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 EV kit’s RJ45 magnetic jack. The EV kit features a 1 x 1 Gigabit RJ45 magnetic jack for separating the DC power provided by an endspan or midspan Ethernet system.
