FM2212 - 12-Port 10-Gigabit Ethernet Switch Chip

The FM2212 fully-integrated single-chip wire-speed 10-Gigabit Ethernet switch chip leads the market in low-latency intelligent switching, delivering cut-through latency as low as 200ns. With its robust layer-2 switching capabilities and the ubiquity of Ethernet, the FM2212 fits comfortably in a number of existing and emerging applications. And, with the unprecedented level of integration, it removes the cost barrier for rapid and far-reaching 10G Ethernet deployment. The FM2224 has 12 interfaces that can independently function in 10G, 2.5G, and 10/100/1000 modes.
