Description
The NWK933 is a single chip 3.3V CMOS physical
layer solution from MII to the magnetics. It is designed
for 10BASE-T and 100BASE-TX Ethernet, based
on the IEEE 802.3 specifications.
The NWK933 is compatible with the Auto Negotiation
section of IEEE 802.3u and provides all the support
needed for the 802.3 Full duplex specification.
