Description

The ST802RT1x is a high-performance fast

Ethernet physical layer interface for 10Base-T,

100Base-TX and 100Base-FX applications. It is

designed using advanced CMOS technology to

provide MII and RMII interfaces for easy

attachment to 10/100 media access controllers

(MAC). The ST802RT1x supports the 100Base-

TX of IEEE802.3u and 10Base-T of IEEE802.3i

and 100Base FX of IEEE 802.3u (B version only).

The ST802RT1x 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 allows for the support of auto-

negotiation functions for speed and duplex

detection. The automatic MDI / MDIX feature

compensates for the use of a crossover cable.

With auto MDIX, the ST802RT1x automatically

detects what is on the other end of the network

cable and switches the TX & RX pin functionality

accordingly.
