Chip Can Forward Packets At OC-48/-192/-768 Speeds

An advanced Ternary Content Addressable Memory (T-CAM) architecture and clock speeds as high as 100 MHz are said to enable the SiberCAM Ultra-2M SCT2000 packet-forwarding engine to perform up to 100 million multi-layer, multi-protocol look-ups per second. With this and other capabilities, the IC can support OC-48 (2.4 Gbits/s), OC-192 (10 Gbits/s) and OC-768 (40 Gbits/s) transmission systems, such as multi-gigabit routers and high-performance Ethernet switches.
The Ultra-2M can hold 64K Layer 3 (IPv4) addresses-- at least twice the capacity of existing CAMs-- and by cascading up to 16 of the devices together, over one million addresses can be supported in a single routing sub-system with no search throughput performance penalty. It also has an independently clocked, synchronous maintenance port that allows look-up table addresses to be updated without interrupting the search path. The 569-pin BGA costs $70 each in volume quantities.
