Hi,

I would like to use PoE at the project that I am working on. It is the application of RTL8019AS - AT89C51ED2 which should be powered via PoE. I have no experience with that so I would like to ask you for a help. Probably I use Si3400 in connection with Bel Fuse MagJack Connector. Don't you have any experience with that? In datasheet there is written that you can use isolated or non-isolated power output from power input. The first case is more difficult and harder to design. I don't know which one should I use. Is necessary to use the isolated power or can I make the design easier with non-isolated one? Thank you very much for you reply and excuse for my English...
