Kyocera Chooses DSPC Chip Set for CDMA Phone Design

Japanese handset manufacturer Kyocera has selected Cupertino, CA-based DSP Communications' (DSPC's) D5421 WorldCDMA chip set. Kyocera will use this system solution during the development of a cdmaOne handset for the Japan wireless market.

The D5421 WorldCDMA baseband chipset is designed 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.

Japanese carrier DDI Corp has already publicly announced the availability of the Kyocera's new cdmaOne handset within its service areas. IDO, another Japanese carrier, will also offer the phones to its customers when it launches its CDMA service in the Kanto and Tokia region of Japan in April.
