Small article from Mar 6 EE Times: AMCC parts promise to lower cost of 10-Gbit/s optical nets By Craig Matsamoto SAN MATEO, CALIF. -Advanced Micro Circuits Corp. (AMCC) has produced what it says are the first high-volume standard parts capable of handling OC-192 (10 Gbit/second) optical networking. The crux of AMCC's offering is Indus, a Sonet framer that aggregates four OC-48 (2.5-Gbit/s) feeds into a single 10Gbit/s stream. The company also has announced silicon-germanium parts for interfacing between Indus and fiber-optic cables. The 53091 and 53092 tap the SiGe process to run at OC-192 speeds. The 53091 and 53092 are a cheaper and simpler alternative to the ASICs that have been used in early OC-192 implementations. They also cater to networking startups that lack the infrastructure to develop such ASICs, said Ken Prentiss, AMCC director of marketing for telecom products. Indus is a 0.25-micron CMOS part developed by Cimarron Communications (Andover, Mass.), which was acquired by AMCC last year. While Indus' CMOS nature keeps costs low and manufacturability high, it also means the part can't truly perform at 10 Gbit/s; it achieves that speed by transmitting or receiving data from a 16bitwide, 622-MHz parallel bus. Ian the case of OC-192 transmission, Indus sends the data feed to the 53091; it serializes the data into a 1-bit-wide, 10-Gbit/s stream, which is fed onto a fiber-optic cable. The corresponding 53092 receiver does the reverse: It collects the OC-192 stream and deserializes it, transmitting it to the Indus across the 16-bit bus. Fruits of a partnership AMCC developed its SiGe technology though a partnership with IBM that began in 1998. "At the time, the market was pretty much covered by gallium arsenide," Prentiss said. But as demand for high-speed optical networking has surprisingly shot up, OEMs have demanded parts that can be produced in higher volumes and at lower costs than GaAs can provide, Prentiss added. Indus is packaged in an 824-pin CCGA and costs $635 in quantities of 1,000. The part is sampling now, with production volumes slated for the second quarter. The 53091 and 53092 come in 148pin flipchip BGA packages and cost $495 in quantities of 1,000. Also on the same subject: biz.yahoo.com
