Applications

Description

The STE101P 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 MII, RMII and SMII interfaces 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 STE101P 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. The

Automatic MDI / MDIX feature compensates for

using a cross over cable. With Auto MDIX, the

STE101P automatically detects what is on the

other end of the network cable and switches the

TX & RX pins accordingly.
