I think I'm beginning to understand.  I'm stepping into a field I'm not 
familiar with but from the looks of things that is a 
serializer/deserializer only.  It is meant to be part of a multi-chip set 
with another chip providing the MAC and protocol functions.

Trying to hookup a lpc2138 directly to this strikes me as an exercise in 
futility.   It might be possible to add FIFO between the two but that's a 
fair amount of work for little return.  Why not hookup a 10base-t 
module?  It would probably still be faster than you can manage.
