AT&T T7220PC IC information...

[William R. Walsh]

Hello all...

The above-mentioned IC is used on an Ethernet adapter that I have here. The
adapter works just fine. I am just curious what this IC does. So far I have
been unable to locate any information on it. What I'd really like to find is
a datasheet or description of its function.

Thanks!

William

Can't help you, but suggest you also do your search using Lucent
Technologies and Agere Systems since AT&T MicroElectronics became Lucent,
then Agere after spin offs in 1996 and 2001 respectively. If I had to
guess, I'd say it is a Physical Layer Ethernet communications or control
chip since this is what AT&T ME specialized in.

Good luck.
