STE100P

10/100 FAST ETHERNET 3.3V TRANSCEIVER

PRODUCT PREVIEW

1.0 DESCRIPTION

The STE100P, also referred to as STEPHY1, is a

high performance Fast Ethernet physical layer inter-

face for 10BASE-T and 100BASE-TX applications.

It was designed with advanced CMOS technology to

provide a Media Independent Interface (MII) for easy

attachment to 10/100 Media Access Controllers

(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-du-

plex operation, at 10 and 100 Mbps operation. Its op-

erating mode can be set using auto-negotiation,

parallel detection or manual control. It also allows for

the support of auto-negotiation functions for speed

and duplex detection.
