We don't add chips; we just replace already established chips,” said Harel, referring to the LNA and PA. Also, while the algorithms run on an ARM [processor], they're processor-independent.” The processing consumes less than 0.5 percent of an ARM7's or ARM9's processing ability, he said.

The device replaces six discrete functions, said Elantec's director of marketing, Sameer Vuyyuru, including a differential input buffer, a 20-dB gain block, an equalizer and a common-mode recovery function.

The IC touts 150 MHz of bandwidth at -3 dB and consumes 33 mA of no-load supply current from a 5-volt supply. Although aimed at KVM applications, the EL9110 can also be used in twisted-pair receiving, VGA over twisted pair and security video applications, Vuyyuru said.

The units are housed in 16-pin QSOP packages with a per-piece price of $6.75 in 1,000-unit quantities.

DALLAS — The CDMA silicon market has seen a long string of challengers run up the slope dominated by king-of-the-hill Qualcomm Inc. and then stagger back down, felled by the technical intricacies of code-division multiple-access technology. Now Texas Instruments Inc. is preparing for a charge, and analysts believe the chip giant may have a shot when it enters the market with a commercial cdma2000 chip set.

Executives speaking at the company's annual analysts' meeting here last week said TI will very soon” announce plans for cdma-2000 merchant silicon that will begin sampling to customers next quarter.

Tom Engibous, TI's president, said the commercial CDMA chip set was developed primarily by a group based in San Diego that came to TI two years ago with the acquisition of CDMA startup Dot Wireless Inc. TI is expected to work with partners for the RF and other portions of the chip set, but Engibous declined to identify them. He said the company's Nokia business unit has separately developed custom silicon that Nokia has used for its successful CDMA handset business.

TI is putting everything in place to offer the CDMA market a more-integrated solution,” said Gilles Delfassy, senior vice president of the company's wireless-terminals business unit. For TI, this is an untapped opportunity in a market where one company has ruled the roost,” said Richard Kerslake, a director in the wireless business unit.

Executives at Qualcomm (San Diego) declined to comment last week. A public relations staffer said the managers were tied up in meetings.

The bad news is that ASIC starts will never return to same levels as the industry experienced at the end of the 1990s, according to Steve Sutton, vice president of Texas Instruments Inc.'s ASIC business.

The market will recover, but it will look different,” Sutton said.

ASICs have become so complex that design and production costs have skyrocketed, resulting in a limited number of new wafer starts, he said.

The common perception is that the extremely high photomask costs at 0.13-micron and 90nm-processing nodes will constrain new ASIC starts.

But while mask costs may jump as high as $1.5 million for 90nm processing, that is only part of the economic problem, Sutton added.
