Product Summary

The LXT9785HC is an 8-port Fast Ethernet PHY Transceiver that supports IEEE 802.3 physical layer applications at both 10Mbps and 100Mbps. This device provides both Serial/Source Synchronous (SMII/SS-SMII) and Reduced Media Independent (RMII) Interfaces for switching and other independent port applications. All network ports provide a combination twisted-pair (TP) or pseudo-ECL (PECL) interface for both 10Mbps or 100Mbps (10BASE-T and 100BASE-TX) Ethernet over twisted-pair, or 100Mbps (100BASE-FX) Ethernet over fiber-optic media. The LXT9785HC provides three discrete LED driver outputs for each port. The device supports both half-duplex and full-duplex operation at 10Mbps and 100Mbps and requires only a single 2.5V power supply.
