Preliminary Data Sheet July 2000 LU3X34FTR Quad 3 V 10/100 Ethernet Transceiver TX/FX Overview The LU3X34FTR is a fully integrated, 4-port 10/100 Mbits/s physical layer device with an integrated transceiver. This part was designed specifically for 10/100 Mbits/s switches. These applications typically require stringent functionality in addition to very tight board space, power, and cost requirements. The LU3X34FTR supports RMII and SMII interfaces, offering the designer multiple reduced pin coun.
