DESCRIPTION

The STE100P, also referred to as STEPHY1, is a

high performance Fast Ethernet physical layer in-

terface for 10Base-T and 100Base-TX applica-

tions.

It was designed with advanced CMOS technology

to provide a Media Independent Interface (MII) for

easy attachment to 10/100 Media Access Control-

lers (MAC) and a physical media interface for

100Base-TX of IEEE802.3u and 10Base-T of

IEEE802.3.

The STEPHY1 supports both half-duplex and full-

duplex operation, at 10 and 100 Mbps operation.

Its operating mode can be set using auto-negotia-

tion, parallel detection or manual control. It also al-

lows for the support of auto-negotiation functions

for speed and duplex detection.
