Product Summary

The BCM5389KFBG is an 8-GE port switch with integrated SerDes. The BCM5389KFBG is is a highly integrated solution ideally suited for standalone Gigabit Ethernet switches and Gigabit Ethernet control plane and backplane applications. The BCM5389KFBG combines all the functions of a high-speed switch system, including packet buffer, SerDes, media access controllers, address management, and a non-blocking switch fabric into a single 0.13μm CMOS device.
