SI3453B-B02-GM Overview
Embedded in the Tray package, it is used by many applications.In this case, it is packaged in the same way as 40-VFQFN Exposed Pad.Controller (PSE) is the type of PoE controller.There is a strong/weak growth in the number of channels: 4.In order to ensure PoE reliability, it is designed to operate at a temperature of -40°C~85°C.This electrical Po E controller receives its supply voltage from 45V~57V.The base part number SI3453 determines the Po E controllers.A 40 termination involves terminating the transmission line with a power over ethernet controller of the same impedance as the line.The ethernet over power controller has 40 pins.The board has 40 pins.It is necessary to have a greater voltage than 3.3V in the supply.To work properly, 4mA needs to receive supply current.A PoE controller such as this will be able to deliver a maximum power output of 40W.
