ST802RT1A - ST Microelectronics

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 100BaseTX of IEEE802.3u and 10Base-T of IEEE802.3i and 100Bas.
