LPC2378 with Ethernet Problem

Started by tmwc...@126.com August 17, 2009
I use RTL8201CL for ethernet phy. But this function is not work.
Has anyone been experience on ethernet and know how to use RTL8201CL for ethernet phy?

An Engineer's Guide to the LPC2100 Series

RTL8201 is MII only, dont?

Dear Marcelo,
I don't know what MII is.
I design it first time.

You should read datasheets then...
LPC23xx ethernet accepts only "RMII" PHYs. RTL8201 is "MII", which need more
signals not available on LPC23xx.
You must select another PHY chip.

Hi

Can someone point to a doc that explains the verious signals
standards RMII PHY , MII etc and what they are used?

I have being trying Google for this but I am sure someone has a good link to one

Regards

Plus the data sheet of any part with an RMII interface.
