10/100/1000BASE-T CONTROLLER WITH INTEGRATED TRANSCEIVER
The BCM5721 is a fully integrated 10/100/1000BASE-T Gigabit Ethernet media access control and physical layer transceiver solution for high-performance network applications. The BCM5721 combines a triple-speed, IEEE 802.3 compliant media access controller (MAC), PCI Express bus interface, on-chip buffer memory, and integrated physical layer transceiver in a single device. The BCM5721 is fabricated in a lowvoltage silicon process, providing an ultra-low power solution. By itself, the BCM5721 provides a complete single-chip Gigabit Ethernet NIC or LOM solution.
