8FE+2GE PORT SWITCH WITH ON-CHIP PACKET BUFFER

The Broadcom BCM5382M 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 802.3x specifications, including the MAC control, pause frame, and autonegotiation subsections, providing compatibility with all industrystandard Ethernet, Fast Ethernet, and Gigabit Ethernet devices.
