ADVANCE DATA SHEET BCM5238 10/100BASE-TX Octal-Φ™ Transceiver GENERAL DESCRIPTION The BCM5238 is an octal 10/100BASE-TX transceiver for Fast Ethernet switches. The device contains eight fullduplex 10BASE-T/100BASE-TX Fast Ethernet transceivers, each of which performs all of the physical layer interface functions for 10BASE-T Ethernet on Category 3, 4 or 5 unshielded twisted-pair (UTP) cable and 100BASE-TX Fast Ethernet on Category 5 UTP cable. Pseudo-100BASE-FX mode is supported through external fiber-optic tranceivers. The BCM5238 is a highly integrated solution using 0.18micron technology, combining digital adaptive equalizers, ADCs, phase locked loops, line drivers, encoders, decoders and all the required support circuitry into a single monolithic CMOS chip.
