DSPC Develops Multi-Mode CDMA Chip Set

DSP Communications (DSPC) has introduced the D5421 WorldCDMA baseband chipset for multi-mode CDMA applications. This new chip set supports the multiple frequency bands and the multiple vocoders used in worldwide CDMA applications. Using this functionality, designers can develop a single CDMA handset that works in multiple countries and supports both 8 and 13 kb/s vocoding rates.

The new chip set includes a single CDMA digital application-specific IC (ASIC) and an analog interface ASIC. In addition, this new solution integrates ARM' ARM7TDMI microcontroller and the OAK digital signal processor (DSP) core.

DSPC plans to offer samples of the D5421 chip set in the fourth quarter of 1998. The D5421 chipset will employ 0.25 µm technology and will run from +2.5 VDC supplies. All ICs in the chip set will be housed in ball-grid-array (BGA) packages.
