Preliminary Data Sheet September 2000 3X38FTR 208-Pin SQFP OCTAL-FET (Fast Ethernet Transceiver) for 10Base-T/100Base-TX/FX Overview The 3X38FTR 208-Pin SQFP is an eight-channel, single-chip plete transceiver designed specifically for dual-speed 10Base-T, 100Base-TX, and 100Base-FX switches and repeaters. It supports simultaneous operation in three separate IEEE - standard modes: 10Base-T, 100Base-TX, and 100Base-FX. The 3X38 uses 0.25 µm low-power CMOS to achieve extremely low power dissipation and operates from a single 3.3 V power supply. Each channel implements the following: s s s s s s s Autopolarity detection and correction. Adjustable squelch level for extended line length...
