SAN DIEGO -- Applied Micro Circuits Corp. here today announced the Ganges, an OC-192 framer that supports full-duplex mapping of asynchronous transfer mode (ATM) cells or packet-over-Sonet (POS) for either concatenated or channelized Sonet/SDH payloads.
Ganges' flexibility and high performance make it ideal use in carrier-class core routers and switches that enable Internet service providers to quadruple the throughput of the IP data networks, according to AMCC. Like its AMCC predecessors, the Ganges also allows for the mapping of any type of traffic, including 10-Gigabit Ethernet.
Ganges joins AMCC's Indus framer IC and the S3091/S3092 PHY chip to form a complete OC-192 product family, allowing AMCC to support any type of traffic including ATM, IP, 10-Gigabit Ethernet, DWDM and TDM at OC-192/STM-64 data rates. "With the acquisition of Yuni Networks, AMCC also has the switch technology to support applications that deliver such explosive bandwidth," said Ram Sudireddy, vice president of digital products at AMCC (see April 20 story).
The new chip was defined with the help of the Terabit Router development community in order to address the existing bottleneck at the core of the IP data network, Sudireddy said. ISPs can take advantage of the device's concatenated mode, which enables maximum use of 10-Gigabit Ethernet bandwidth.
Ganges also supports channelized traffic, a requirement for the big carrier-class ATM switches. ATM switches use the channels to provision the switch on STS boundaries. This capability enables the carrier to efficiently provision the bandwidth based on customer need and priority. Ganges can split the 10-Gigabit OC-192/STM-64 into 16 channels of 622-megabits-per-second STS-12, four channels of 2.5-gigabits/sec., or any logical combination.
Packaged in a 624-pin CBGA and manufactured in 0.18-micron CMOS, the Ganges (designated S19202) is priced at $725 in quantities of 1,000. Currently sampling to development partners, volume production is scheduled for the third quarter.
