STE100P
10/100 FAST ETHERNET 3.3V TRANSCEIVER
1 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.
