STMicroelectronics introduces ST802RT1  10/100 Ethernet transceivers

ST802RT1 is a high performance Fast Ethernet physical layer interface for 10Base-T, 100Base-TX and 100Base-FX applications. It is designed with advanced CMOS technology to provide MII and RMII interfaces for easy attachments to 10/100 Media Access Controllers. ST802RT1 supports the 10Base-T of IEEE802.3i, 100Base-TX of IEEE802.3u and 100Base FX of IEEE 802.3u (only B version).

The ST802RT1 supports both half-duplex and full-duplex operation at 10 and 100Mbps speed. Its operating mode can be set using auto negotiation, parallel detection or manual control. It also allows the support of auto-negotiation functions for speed and duplex detection.
Utilizing the Auto MDI-X feature, the ST802RT1 automatically detects what is on the other end of the network cable and switches the TX & RX pins functionality accordingly.
