MAX5969BEVKIT+

MAX5969BEVKIT+ is a MAX5969B evaluation kit (EV kit) which is a fully assembled and tested surface-mount circuit board featuring an Ethernet port, network powered-device (PD) interface-controller circuit for IEEE® 802.3af/at-compliant power-over-Ethernet (PoE) systems. The EV kit features the MAX5969B IEEE 802.3af/at-compliant network PD interface controller IC in a 10-pin TDFN package. The MAX5969B is used in PoE applications requiring DC power from an Ethernet network port for PDs such as IP phones, wireless access nodes, and security cameras. The EV kit receives power from IEEE 802.3af/at-compliant power-sourcing equipment (PSE). The PSE provides the required -30V 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 1GbE RJ45 magnetic jack and two diode bridges for separating the DC power provided by an end span or midspan Ethernet system. The EV kit can also be powered by a wall adapter power source.
