Analog Devices Introduces Global System for Mobile Communications

12/22/2003 - TTPCom's partner, Analog Devices, Inc. (NYSE: ADI) announced that the first GSM (Global System for Mobile Communications) mobile phones resulting from a joint development program with Chinese manufacturer, TCL Mobile Communication Co., Ltd., have entered mass production after successfully completing GCF (Global Certification Forum) testing. A host of ADI’s high-performance analog and digital signal processing chips enable advanced media features such as color displays, camera, games and polyphonic ring tones, with optional features such as JavaTM, speech recognition, hands-free operation and GPRS (General Packet Radio Service) data service. The new phones include the SoftFone® baseband chipset and Othello® direct conversion radio frequency IC.

“ADI’s SoftFone chipset and development tools have enabled the fast addition of new features and capabilities to our phones, allowing us to develop a broad range of products based on the same platform,” according to Du Xiaopeng, Executive VP of TCL Mobile. “Because we have used ADI chipsets for several previous midrange products, we have been able to leverage our R&D expertise with SoftFone to add media-rich features to our product line, increasing the ease with which we can deploy phones with advanced features to our customers".

“TCL is one of the leading domestic Chinese handset manufacturers and it is an honor to work with them on this program,” said Brian McAloon, group vice president and general manager, Digital Signal Processing Systems division, Analog Devices, Inc. “These new phones have features and performance comparable to the best phones in the global market".

The collaboratively developed Analog Devices/TCL platform is based on the SoftFone RAM-based digital baseband processor family incorporating the digital signal processing (DSP), microcontroller, GSM logic, fast on-chip SRAM, and high-performance analog baseband interface with integrated power-management circuits and stereo audio playback capability. The radio section of the platform is based on the award-winning Othello OneTM direct-conversion radio transceiver. The platform can operate in up to four GSM frequency bands, enabling operation in Asia, Europe and North America. Protocol stack software for the platform is supplied by TTPCom of Cambridge, England.
