BCM5702 OVERVIEW

The BCM5702 is a fully-integrated 10/100/1000BASE-T Gigabit Ethernet media access control and physical layer transceiver solution for high-performance network applications. The BCM5702 is a highly integrated solution combining a triple-speed, IEEE 802.3 compliant media access controller (MAC), PCI bus interfaces, an on-chip buffer memory, and an integrated physical layer transceiver in a single device. The BCM5702 is fabricated in a low-voltage 0.13-μm CMOS process, providing a low-power system solution. By itself the BCM5702 provides a complete, single-chip, Gigabit Ethernet NIC or LOM solution.
