ST802RT1A 10/100 real-time Ethernet 3.3 V transceiver
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 autonegotiation 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
