Hello, I am starting an investigation to determine the easiest migration path to move an existing product from 10 Base-T ethernet to 100 Base-T ethernet. The current product is a small embedded system running Linux (2.4.9 kernel) on a StrongArm processor, using the CrystalLAN CS8900A chip for the MAC/PHY. This chip is in a 100-pin QFP package.
I'd love to hear that there is a drop in replacement for this chip that will allow us to move up to 100 MBps without much trouble, but I've looked around and can't see to find any after a first pass. I did find an application note from SMSC entitled "Migrating from a 10 Mbps Ethenet Controller to the SMSC LAN91C111" which does support 100 Mbps, but it isn't exactly "pin-compatible" from what I can see.
Any other solutions out there?
Thanks in advance for the help...
John O
