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.
