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.
