PHY for AT91RM9200 ?

Started by George Pontis November 6, 2006
Just beginning a new design here, built on the AT91RM9200. I am
searching for RoHS-compliant components that will be available now and
hopefully well into the future. First up is a enet PHY.

AMD says that they have successfully tested these PHY chips: Intel
LXT971A, Davicom DM9161E, AMD Am79C874.

However, the chip that seems to be most readily available (and low
power) is the National DP83848C. Is the MII standard complete enough to
ensure that the DP83848C would work if I design it in ?

It works, no problems whatsoever. --- ****************************************************************** * KSI@home KOI8 Net < > The impossible we do immediately. * * Las Vegas NV, USA < > Miracles require 24-hour notice. * ****************************************************************** -- Posted via a free Usenet account from http://www.teranews.com

Excellent, thanks for the feedback. Was that in RMII or MII connection ? --

I used RMII. --- ****************************************************************** * KSI@home KOI8 Net < > The impossible we do immediately. * * Las Vegas NV, USA < > Miracles require 24-hour notice. * ****************************************************************** -- Posted via a free Usenet account from http://www.teranews.com
