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 count interfaces to save both real estate and cost in system design. The LU3X34FTR was designed from the beginning to conform fully with all pertinent specifications, from the ISO 1/ IEC 2 11801 and EIA 3/TIA 568 cabling guidelines to ANSI 4 X3.263TP-PMD to IEEE 5 802.3 Ethernet specifications.
