STE100P

10/100快速以太网收发器3.3V 10/100 FAST ETHERNET 3.3V TRANSCEIVER

The , also referred to as STEPHY1, is a high performance Fast Ethernet physical layer interface 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-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.
