San Jose, Calif. Power X Networks Inc. has added the SP-200 switch fabric line card IC to its TeraChannel switch fabric chip set for designers of switches and routers.
The line card IC is said to offer fully redundant port and fabric capability to reduce system downtime, two-times overspeed operation to effectively double internal port bandwidth and the ability to accommodate a wide range of common switch interface (CSIX) frame size options. The company said latter ability provides maximum switch implementation efficiency regardless of traffic protocol.
Bill Weir, vice president of marketing, said per-port and fabric redundancy is an essential feature in carrier-class environments where packet loss due to system downtime is unacceptable. The redundancy capability allows real-time transfer of line and fabric card functionality within the switch from the existing cards to standby cards, he said. The SP-200 also supports hot-swap capability, also intended to eliminate downtime.
Weir added that the overspeed feature is useful in variable-packet-size environments, which are common in Internet Protocol and Ethernet-based traffic. The feature includes the transfer of minimum size packets with no saturation.
CSIX frame size options range from 29 through 89 payload bytes in 12-byte increments, for efficiency across commonly used protocols like ATM, Gigabit Ethernet and IP.
Other features include synchronous transmit and receive; embedded physical-layer high-speed, serial-link technology; CSIX interconnect to the network processor; and provisions for up to 321 virtual output queues in a 16-port implementation.
Designed in Power X's mixed-signal CMOS technology, the SP-200 offers typical power dissipation of 3.5 watts. The part will be packaged in a 672-pin ball grid array and priced at $295 in sample quantities. Samples are expected in the fourth quarter.
