The FocalPoint family of 10-Gbit Ethernet switch chips contains fully integrated solutions with as many as 24 10-Gbit Ethernet ports. At the core of each chip are the company's patented highthroughput Terabit crossbar and RapidArray packet memory technology. The crossbar can deliver more than a terabit/s of non-blocking throughput with an internal latency of less than 3 ns. The FM2224's 24 quad serializer-deserializer (SERDES) 10-Gbit Ethernet interfaces can be configured to operate at 10 or 2.5 Gbits/s or 1 Gbit/s as well as 100 and 10 Mbits/s. The FM2112 packs eight quad SERDES 10-Gbit interfaces along with 16 single SERDES interfaces that can support 2.5 Gbits/s or 1 Gbit/s or 100- or 10-Mbit/s operating modes. Each 10-Gbit port on the switch chips contains an integrated 10-Gbit XAUI interface and 8 Mbits of on-chip packet storage. The chips also provide standards-compliant layer 2 Ethernet switch features, including port and MAC-based virtual local-area networks, link aggregation, port-and MAC-based security, and spanning tree link management. Samples of both chips are available. In quantities of 5000, the FM2112 and FM2224 cost $285 and $450 each, respectively.
