Broadcom BCM5228
The BCM5228 is an octal 10/100BASE-TX/FX transceiver targeted at Fast Ethernet switches. The device contains eight full-duplex 10BASE-T/100BASETX/FX Fast Ethernet transceivers, each of which perform 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. The 100BASE-FX is supported at each port through the use of external fiberoptic transmit and receive devices.| Part No. | BCM5228 |

GENERAL DESCRIPTION
FEATURES
The BCM5228 is a highly integrated solution combining digital adaptive equalizers, ADCs, phase locked loops, line drivers, encoders, decoders, and the required support circuitry into a single monolithic CMOS chip. The BCM5228 complies with the IEEE 802.3 specification, including the auto-negotiation subsections. The effective use of digital technology in the BCM5228 design results in robust performance over a broad range of operating scenarios. Problems inherent to mixedsignal implementations (such as analog offset and onchip noise) are eliminated by employing field-proven digital adaptive equalization and digital clock recovery techniques.● 10BASE-T/100BASE-TX/FX IEEE 802.3u compliant
