The services, aimed at businesses and government agencies, include switched voice, dedicated voice, long distance, virtual private networks, Asynchronous Transfer Mode and Internet Protocol service.

Agere expects to have the 90-nm serdes block available for ASICs next summer. The company did not say when a standalone 90-nm serdes chip would be available.

MANHASSET, N.Y. ” Demand for integrated RF mobile-handset devices has been pallid so far, but that's expected to change as next-generation phone standards prompt redesigns to accommodate the attendant shifts in technology. Suppliers thus are stepping up development of integrated RF devices, and some are reporting a pickup in business as new phone models emerge.

Suppliers are integrating antenna switches and SAW filters into front-end modules and are integrating power amps with auxiliary control circuitry to form power amplifier modules. But with low-cost phones still dominating mobile-phone shipments, demand for older, discrete parts such as SAW filters remains strong, forcing suppliers to continue to stock them along with the integrated solutions they're developing for next-generation handsets.

It remains to be seen whether the high end will pick up,” said Philip Gadd, worldwide marketing manager for the Wireless Semiconductor division of Agilent Technologies Inc. (San Jose, Calif.). The slower-than-expected rollout of third-generation phones has been one factor in the lackluster device sales thus far, Gadd said.

Because 3G and advanced phones are more apt to incorporate features such as gaming and Internet access, they are more likely to use integrated parts to pack more functions in a smaller space. But analysts say OEMs will balk at designing in integrated parts if those devices raise the cost of the phone. Mobile-phone suppliers want to reduce costs as they increase functionality,” said Scott Smyser, an analyst for iSuppli Corp. (El Segundo, Calif.). They want the functionality but don't want to pay a premium.”

Though analysts and suppliers say the cost premium for integrated parts is difficult to quantify, they acknowledge that limited production yield often results in the integrated devices' commanding a premium over discrete parts.

We have lots of work to do in reducing cost,” said Greg Thompson, vice president of sales for RF Micro Devices Inc. (Greensboro, N.C.). People are looking for the best performance and smallest size. We're working on smaller die geometries, better yields ” anything to reduce cost.”

But there's evidence the pendulum is starting to swing in favor of integrated RF parts.

According to iSuppli, sales of older discrete mobile-phone parts such as SAW filters and synthesizers are slated to decline in the next few years. Sales of integrated parts like RF transceivers, power amplifiers, front-end switches and duplexers will grow as 2.5- and 3G phones increasingly replace 2G designs, the firm said.

Research firm In-Stat/MDR (Phoenix) pegs the structured-ASIC market at $30 million this year, with growth to $760 million by 2007, according to analyst Jerry Worchel. And that picture is backed up by various vendor reports from the field.

We are definitely seeing traction for the concept,” said Doug Bailey, vice president of marketing at Chip Express Corp. (Santa Clara, Calif.). The company is seeing 10 percent quarter-on-quarter revenue growth, Bailey said. In addition, its book-to-bill ratio hit 1.6 in the third quarter and is likely to be near 1.2 in the fourth quarter.

The encouraging thing for the long term is that big companies are starting to vet structured-ASIC vendors specifically,” Bailey said. We have people calling and asking for structured ASICs for a portion of their planned ASIC designs next year.”

Other vendors related similar experiences. AMI Semiconductor Inc. (Pocatello, Idaho) reported 18 percent growth in its structured products between the second and third quarters. NEC Electronics America Inc. (Santa Clara, Calif.) also has seen significant growth, according to NEC associate vice president and general manager Phillip LoPresti. We are starting to see RFQs specifically asking for structured devices,” he said.

And Fujitsu Microelectronics America Inc. (San Jose, Calif.) reported that customer acceptance of its AccelArray has been so rapid that the company is expanding the staff of the structured products group to support the designs.
