PD81101 Description
RPF PSE Manager PD81101 Introduction Microchip's PD81101 Reverse Power Feeding (RPF) manager is a mixed-signal, high-voltage IC, which integrates power, analog, and logic into a single 56-pin, plastic QFN package. It allows Customer Premises Equipment (CPE) devices and Distribution Point Units (DPU) to share and deliver power and data over the same cable. Microchip's PD81000 RPF controller is a cost-effective,...
