FREMONT, Calif. ( ChipWire)-- Centillium Communications Inc. here is sampling a four-port chip set for asymmetric digital subscriber lines (ADSL) that it calls the most highly integrated, least power hungry ADSL
product available today, said Al Gharakhanian, marketing director for Centillium's network access products. The two-chip CopperFlite product consumes less than 1 watt, and can support any of several ADSL formats.
Aimed at central office equipment, CopperFlite is sampling now to most of Centillium's current customers. Among OEMs using the company's current products are Copper Mountain Networks Inc., Orckit Communications Ltd. and Promatory Communications Inc., among others. The chip set is scheduled to ramp into volume production in March, and Gharakhanian said the company is in negotiations with at least two other major vendors interested in using it.
Although pricing has not been released yet, Gharakhanian said "we don't claim to be the least expensive in the industry. We just claim to be the best solution that's available." Gharakhanian said most vendors consider density and power consumption even more important than cost, which would give CopperFlite an advantage, he said.
The chip set features an analog CMOS front end, which is manufactured by Taiwan's UMC Group, and a digital CMOS back end, produced by Mitsubishi. Along with an external driver and some
other necessary component, Gharakhanian said a total of six active chips are required to implement an entire four-port system. "We're used to systems that need three or four chips to drive a single port,
so this is a real improvement," he said.
Since the chip set is software programmable, it can be used with several different ADSL formats, including full-rate ADSL and the slower, G.Lite version. It can also work with the Japanese G.Lite
annex-C standard, and Centillium claims to be the only vendor in the industry currently fielding a product for that specification.
