10/100BASE-TX OCTAL-Φ™ TRANSCEIVER

The Broadcom BCM5238 is a single-chip device 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 BCM5238 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 BCM5238 is compliant with the IEEE 802.3 standard.
