LU3X54FT Datasheet | Agere Systems

Data Sheet July 2000 LU3X54FT QUAD-FET (Fast Ethernet Transceiver) for 10Base-T/100Base-TX/FX Introduction The LU3X54FT 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. Each channel implements: 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 filtering eliminates the need for external filters Half-...
