LAN91C111 reference hardware design

I'm having trouble locating a reference hardware design for the LAN91C111 chip. I need to have 10/100 ethernet in my soft processor. If I understand my options, I can either use a standalone...

Thanks for the link. Funny you mention the state machine approach because the vast majority of my design is state machine based. I too have a very low data rate need, I am currently fitting all of my data (without much protocol overhead) into a 460 Kbps RS-422 line.

Probably for electrical isolation issues, we need to locate the ethernet magnetics on a separate board away from the main FPGA board. I wonder if I could make this chip work on a separate board.

Anyway, thank you very much. If you still have state machine code to interface to this chip handy, I would be interested.
