OVERVIEW

The Broadcom BCM5384 device is a highly integrated solution. It combines all the functions of a high-speed switch system, including packet buffer, PHY transceivers, media access controllers, address management, and a nonblocking switch fabric into a single 0.13 µm CMOS device. It complies with IEEE 802.3, 802.3u, 802.3ab, and 802.3x specifications, including the MAC control, pause frame, and auto-negotiation subsections, providing compatibility with all industrystandard Ethernet, Fast Ethernet, and Gigabit Ethernet devices.
