hi, I am working design an LTPoE++ PD which require 90W power. I am using LT4275 as PD controller and ENC28J60 as ethernet controller. The goal is making a pi compute module(raspberry pi CM3) powered and connected to the internet. right now, the ENC28J60 can make it connect to the internet without using LT4275 and PoE feature, and LT4275 can support the power with no problem. However, when put them together, the ethernet part stops working. I check the backward compatibility and known it not work with other types of PSE, so we get a 90W PoE Injector which supports bt, but it still not working. I also try to change CLS and CLS++ resistors to reduce the power requirement, it also not working. do anyone can give a help?
