FM3103 - 6-Port Multi-Speed Ethernet Multi-Layer Switch
The FM3103 is a single chip wire-speed 10-Gigabit Ethernet multi-layer switch chip that leads the market in low-latency deep packet inspection along with providing the QoS and congestion management features required in applications such as Telecom backplanes and Carrier Ethernet switch-routers. The FM3103 has 2 interfaces that can independently function in 10G XAUI, or 10/100/1000/2500 SGMII modes, and 4 interfaces that can independently function in 10/100/1000/2500 SGMII modes.
