Silvertel Ag5412 | Demoboard ANX-POE-Power

Available power over PoE

Overview

TopologyLAN / POE
Output 112 V
IC revision1.1

Description

There is a common misconception regarding the power available to a device with Power over Ethernet (PoE) over the advertised power available for each standard. This application note is created as a guide to help understand the power available, and where power can be lost in a PoE application, in order to assist in adhering to the correct power limits when implementing a Silvertel module into an application such that (classification) power limits are not being exceeded.
