LU3X54FTL Datasheet | Agere Systems

Data Sheet July 2000 LU3X54FTL QUAD-FET for 10Base-T/100Base-TX/FX Introduction Configuration The LU3X54FTL is a four-channel, single-chip plete transceiver designed specifically for dual-speed 10Base-T, 100Base-TX, and 100Base-FX repeaters and switches. It supports simultaneous operation in three separate IEEE standard modes: 10Base-T, 100Base-TX, and 100Base-FX. The LU3X54FTL provides a 3.3 V or 5.0 V MII interface logic level. Each channel implements: s s s s s s Autopolarity detection and correction Adjustable squelch level for extended line length capability (two levels) Interfaces with IEEE 802.3u media independent interface (MII) or a serial 10 Mbits/s 7-pin interface On-chip...
