Quad Integrated BroadR-Reach™ Power Over Ethernet (PoE) Controller

The BCM59105 is a highly integrated quad PSE controller compatible with BroadR-Reach technology. The controller extends the distance of PoE to 500m and CAN be used on a single twisted-pair, so that PoE Ethernet and IP services CAN be deployed over installed telephone wiring. The PSE controller CAN also be used with coax cable for IP Video solutions that extend beyond 100m. The controller is the first in the industry to offer a highly integrated architecture with revolutionary enhancements that are targeted at reducing the complexity of PoE designs for BroadR-Reach applications. The BCM59105 integrates the Microcontroller Power Switches low-loss Current Sense function, detection, classification, and voltage converters 3.3V bias Regulator (DC:DC converter) and AC disconnect functionality. The high-level of integration and innovation make the device the most power efficient integrated IEEE 802.3at PoE system. By Broadcom Corp.
