LXT9784

Low-Power Octal PHY

Datasheet

The LXT9784 is an eight-port Fast Ethernet PHY Transceiver supporting IEEE 802.3 10Mbps

and 100Mbps physical layer applications. It provides both a Reduced Media Independent

Interface (RMII) and a Serial Media Independent Interface (SMII) for switching and other

independent port applications. In RMII mode, each PHY has a discrete exposed RMII interface,

and in SMII mode a discrete exposed SMII interface. All network ports provide a Twisted-Pair

(TP) interface for a 10/100BASE-TX connection.

The LXT9784 provides three discrete LED driver outputs for each port. The device supports

both half- and full-duplex 10Mbps and 100Mbps operation, and requires only a single 3.3V

power supply. For low power applications the devices may be powered by a single 3.0V power

supply. Advanced design techniques result in very low power requirements.

The LXT9784 also supports an auto-MDIX feature as well as an integrated Hardware Integrity

(HWI) feature that utilizes a Time Domain Reflectometry (TDR) technique to locate and report

problems with the cable plant.
