Power over Ethernet (PoE) enables power to be delivered over the same ethernet cable as data with no danger of cross-talk, interference, or corruption of the data streams. This reference design showcases end-to-end power tree for an IP network camera powered using PoE or 12-V adapter based on the TI’s DaVinci™ Digital Media Processor or different application processor. The power tree also derives rails required for different peripherals of an IP network camera like: Image sensor, motor control, Ethernet PHY, RS485 interface, IR LED illumination, audio, motion sensing and the alarm interface.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
