OVERVIEW
The BCM5703 is a fully integrated 10/100/1000BASE-T Gigabit Ethernet media access control and physical layer transceiver solution for high performance network applications. The BCM5703 is a highly integrated solution combining a triple-speed, IEEE 802.3 compliant media access controller (MAC), PCI and PCI-X bus interfaces, an onchip buffer memory, and an integrated physical layer transceiver in a single device. The BCM5703 is fabricated in a low-voltage, 0.13-µm CMOS process providing a low-power system solution. The BCM5703 provides a complete single-chip Gigabit Ethernet NIC or LOM solution.
