| 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. 2.0 FEATURE 2.1 Industry standard * IEEE802.3u 100BASE-TX / FX and IEEE802.3 10BASE-T compliant Figure 1.
