Analog Devices Highlights TD-SCDMA Technology Achievements at 3G Mobile International Summit & Exhibition; Analog Devices Will Showcase Its SoftFone-LCR Chipset Capable of Making Live TD-SCDMA Voice and Data Calls.

NORWOOD, Mass. -- Analog Devices, Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal processing applications, today announced that it will be highlighting its innovative 3G cellular technology at the China 3G Mobile International Summit & Exhibition taking place at the China World Hotel in Beijing on June 28 and 29. Taking center stage will be Analog Devices' SoftFone(R)-LCR chipset, a flexible, highly integrated solution for developers of 3G mobile terminals based on the TD-SCDMA Low Chip Rate (LCR) air interface, which continues to gain momentum as one of the 3G technologies expected to be implemented in China. The SoftFone-LCR chipset incorporates all the functions necessary to build a TD-SCDMA handset, including the baseband signal processing and control, analog-interface functions and radio, making it the industry's only complete TD-SCDMA solution from a single silicon supplier.

Currently capable of making live TD-SCDMA voice and data calls, the SoftFone-LCR chipset is also featured as the core component in the DTivy(TM)--A Series reference design from Datang Mobile, the developer of the TD-SCDMA standard. Designed through a collaborate effort between Analog Devices and Datang Mobile, the DTivy--A Series reference design is a complete hardware and software solution providing significant BOM savings and faster time-to-market to manufacturers of next-generation 3G TD-SCDMA products such as high-end camera phones, camcorder phones, multimedia phones, and video phones.

Also at the summit, Lining Wang of Analog Devices RF and wireless systems group, will lead a technical presentation on delivering next-generation mobile devices through software and semiconductor innovation. Mr. Wang's presentation will cover challenges faced by handset designers and highlight technology solutions that incorporate reconfigurable analog functions and software-based radio architectures. The presentation will take place on Wednesday, June 29 at 4:40 p.m. local time.

"We are very excited with the industry momentum that is continuing to build around the TD-SCDMA standard as well as our SoftFone-LCR chipset," said Christian Kermarrec, vice president, RF and wireless systems, Analog Devices, Inc. "Because TD-SCDMA uses unpaired frequency bands and is very efficient in its use of spectrum, we believe that it is a good underlying technology for 3G cellular networks in China."

The China 3G Mobile International Summit & Exhibition is intended to bring together leading mobile operators and service providers, infrastructure providers, chipset suppliers, handset developers, content providers and application developers from China and around the world. Discussions will focus on the hottest issues for China in launching 3G, including policies and regulatory initiatives for the 3G market, case studies and lessons from leading international 3G operator deployments, as well as strategies for developing the market for new 3G mobile services and applications in China.

About the SoftFone-LCR Chipset

Analog Devices' SoftFone-LCR chipset is based on the popular RAM-based SoftFone architecture used in Analog Devices' GSM/GPRS, EDGE, and W-CDMA chipsets. The chipset incorporates a digital baseband processor, which is based on Analog Devices' successful Blackfin(R) Processor, achieving more than 250 MHz performance and exceptionally low power consumption through Blackfin's Dynamic Power Management capability. The SoftFone-LCR's baseband signal processing, including joint detection and decoding, is performed entirely in software running on the embedded Blackfin Processor core instead of a hardware implementation. This allows terminal developers to quickly and easily adapt to any changes necessary as the initial TD-SCDMA networks rollout.

The SoftFone-LCR's analog baseband and power management IC provides a full set of audio features, as well as efficient power management. The SoftFone-LCR chipset also includes the Othello(R)-W direct-conversion radio transceiver, offering solid performance and flexibility for either LCR time division duplex (TDD) or W-CDMA frequency division duplex (FDD) terminals. Additionally, the SoftFone-LCR chipset includes interfaces for cameras, color displays, IR, USB and SD/MMC, allowing handset manufacturers to create several designs with varying levels of feature sets for a wide range of phone models. Analog Devices is unique among chipset suppliers of TD-SCDMA solutions in offering a complete baseband and RF chipset solution, which enables complete signal chain optimization and highly integrated and cost effective solutions.

About TD-SCDMA

The TD-SCDMA (Time-Division - Synchronous Code-Division Multiple Access) standard was proposed by the China Wireless Telecommunication Standards group (CWTS) and approved by the 3GPP (3rd Generation Partnership Project) as the low-chip-rate TDD standard of the 3G standard family. Designed for 1.6 MHz channels, it is compatible with 5 MHz unpaired 3G bands in any region of the world. TD-SCDMA can serve as a complement to W-CDMA deployments since it uses the same network backbone.

The use of time-division duplexing allows the network to adapt dynamically to varying combinations of voice and data traffic, allocating uplink and downlink time slots as needed and using spectrum more efficiently than frequency-division duplexing. In addition, the cost of terminals is reduced by eliminating the need for duplex filters.

The TD-SCDMA standard has been further developed by numerous Chinese and multinational corporations and consortia. Additional details are available at www.tdscdma-forum.org.
