STMICROELECTRONICS STE800P

STE800P
10/100 BASE-TX/FX 8 PORT TRANSCEIVER
PRODUCT PREVIEW
1.0 DESCRIPTION
The STE800P is a high performance Octal Fast
Ethernet physical layer interface for 10BASE-T and
100BASE-TX/ FX applications.
It was designed with advanced CMOS technology to
provide a RMII/SMII for easy attachment to 10/100
Media Access Controllers (MAC) and a physical media interface for 100BASE-TX / FX of IEEE802.3u
and 10BASE-T of IEEE802.3.
The STE800P supports both half-duplex and full-duplex operation, at 10 and 100 Mbps operation. Its operating 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.
