Highly integrated, cost-effective unmanaged-smart gigabit switch. The switch design is based on the field-proven, industry-leading ROBO architecture.This device combines all the functions of a high-speed switch system including packet buffers, PHY transceivers, media access controllers (MACs), address management, port-based rate control and a non-blocking switch fabric into a single 65 nm CMOS device. Designed to be fully compliant with the IEEE 802.3 and IEEE 802.3x specifications, including the MAC-control PAUSE frame, the BCM53128 provides compatibility with all industry-standard Ethernet, Fast Ethernet and Gigabit Ethernet (GbE) devices. The BCM53128 has a rich feature set suitable for not only standard GbE connectivity for desktop and laptop PCs, but also for next-generation gaming consoles, set-top boxes, networked DVD players and home theater receivers. It is also specifically designed for next-generation Small Office/Home Office and Small/Medium Business routers and gateways.
