GENERAL DESCRIPTION
The STE100P, 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 and 10BASE-T. The twisted pair interface directly drives a 10/100 twisted pair connection. STE100P is an excellent device perfectly suited for hub, switch, router and other embedded Ethernet applications.
