BCM5389IFBG [Broadcom]

The Broadcom BCM5389 is a highly integrated switch-on-a-chip solution that combines all functions of a high-speed switch system, including packet buffer, SerDes, MACs, address management, and 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, integrating eight SerDes cores and nine IEEE compliant 10/100/1000 MACs. The device supports jumbo frames (9-KB), VLAN (4k 802.1Q or port-based), port trunking with load balancing, QoS (802.1p and DiffServ), rate control, Spanning Tree, and more. It operates at low power (<1.5W) in a fanless design and is packaged in a small 256-pin FBGA (17 mm x 17 mm).
