Ethernet Switch Chips Smash Latency, Cost Barrier

Switch and Memory Technology Drives Low Latency

At the core of both devices are two patented Fulcrum technology blocks: Nexus(R) Terabit Crossbar and RapidArray(TM) Packet Memory. Nexus leverages Fulcrum's asynchronous technology foundation to deliver more than a Terabit-per-second of non-blocking throughput with 3ns of internal latency. RapidArray combines the ultra-fast data path of the Nexus crossbar with standard foundry state bits to deliver packet memories that offer twice the throughput of commercial memories, while maintaining comparable density and yield.

Both Nexus and RapidArray are power-efficient technologies, drawing about half the power per port of competing solutions and consuming power in direct proportion to traffic load. This results in power consumption of a modest 150mW per Gbps under full load.

Pricing and Availability

Both chips will be sampling in January 2006. The US list price for the 24-port FM2224 is $450 in 5,000 unit quantities (less than $20 per port); the price for the 8/16-port FM2112 is $265 in 10,000 unit quantities. A fully-integrated 1U-high evaluation platform containing 24 10-Gigabit Ethernet CX4 interfaces will be available in January for rapid test and development.
