Product Summary
The BCM5238BA3KFB is an octal transceiver containing eight independent Fast Ethernet transceivers. Each performs all the physical layer functions for 100BASE-TX full- or half-duplex Ethernet on Category 5 UTP cable and 10BASE-T full- or half-duplex Ethernet on Category 3, 4, or 5 UTP cable. The BCM5238BA3KFB chip performs encoding and decoding, clock and data recovery, digital adaptive equalization, line transmission, carrier sense and link integrity monitoring, autonegotiation and RMII/SMII management functions. The BCM5238BA3KFB is compliant with the IEEE 802.3 standard.
