August 10, 1998, Issue: 1121 Section: Communications CDMA chipsets keep coming Mark LaPedus Silicon Valley -- The gradual deployment of CDMA (Code Division Multiple Access) technology in the worldwide cellular arena is prompting numerous chip makers to develop products designed especially for this emerging standard. One such company is PrairieComm Inc., a small, little-known fab- less IC house in Arlington Heights, Ill., which plans to play in the big leagues by quietly showing OEMs its first device that supports the CDMA cellular standard. PrairieComm's new product, the 21C CDMA Baseband Processor, combines several elements in a single IC. These include a 32-bit RISC processor from Advanced RISC Machines Ltd. and an Oak digital signal processor core from the DSP Group Inc. Designed for use in dual-mode handsets, the 21C will begin shipping in volume in early 1999, according to Andrew Yu, corporate marketing manager for PrairieComm. Like most cellular-chip makers, PrairieComm is scrambling to get its CDMA chipset out the door for good reason. The cellular world is slowly moving toward a "third-generation" (3G) protocol based on CDMA. However, several companies are currently battling over two new, competing 3G CDMA standards-Wideband cdmaOne and W-CDMA. "We're not driving the standards, so we have to position ourselves to support whatever [CDMA] standard comes out," Yu said. On the chip side, meanwhile, DSP Communications Inc., Qualcomm Inc., and VLSI Technology Inc. are now either shipping or sampling CDMA chipsets. LSI Logic Corp. will ship its CDMA chipset in the second half of this year, while Lucent Technologies Inc.'s Microelectronics Group and others will soon introduce similar products. But buyers should beware, according to analyst Ray Jodoin of In-Stat Inc., Scottsdale, Ariz. "A lot of companies have announced CDMA chipsets, but it takes a huge depth of technical expertise to develop real silicon," he said. PrairieComm, which now sells parts for the rival GSM cellular standard, has high hopes for this CDMA device. The part consumes only 2.7 to 3.6 V and uses standard serial I/O and RF components.
