NORWOOD, Mass. -- Analog Devices, Inc. (NYSE NYSE
See: New York Stock Exchange : ADI), a global leader in high-performance semiconductors for signal processing applications, today announced the availability of its second-generation chipset for developers of advanced multimedia mobile handsets based on the 3G TD-SCDMA Low Chip Rate (LCR See least cost routing. ) air interface. The new SoftFone[R]-LCR+ chipset expands Analog Devices' portfolio of TD-SCDMA technology solutions and builds upon the company's legacy as a leader in TD-SCDMA technology development by adding support for a wide range of enhanced multimedia functions. Analog Devices became the first company to offer a complete TD-SCDMA chipset from a single supplier and the company's SoftFone chipsets have been an integral part of network trials held by wireless operators in China over the past three years, most recently achieving dual-mode operation and completing file transfers on a 384 kbps data connection with its SoftFone-LCR+ chipset. In addition, Analog Devices and its SoftFone-LCR chipsets have achieved successful market adoption, as evidenced by design wins with leading 3G TD-SCDMA handset manufacturers, including ZTE ZTE Zalaegerszegi Torna Egylet (Hungarian sports club) Corporation, Holley Communications and Inventec, along with leading Chinese mobile phone design houses, including Longcheer and Simcom.
The TD-SCDMA (Time-Division - Synchronous Code-Division Multiple Access) standard was proposed by the China Wireless Telecommunication Standards group (CWTS CWTS Civic Welfare Training Service (Phillipines)
CWTS Christian Witness Theological Seminary (Concord, CA)
CWTS Chinese Wireless Telecommunication Standard ) and approved by the 3GPP GPP Government Performance Project
GPP General Purpose Processor
GPP General Physical Preparedness
GPP Gambian People's Party
GPP Good Pharmacy Practice
GPP Gross Primary Productivity
GPP Green Procurement Program
GPP Generic Packetized Protocol (3rd Generation Partnership Project) as the low-chip-rate TDD (Time Division Duplexing) A transmission method that uses only one channel for transmitting and receiving, separating them by different time slots. No guard band is used. Contrast with FDD. See also TDD/TTY.
TDD - Telecommunications Device for the Deaf 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 See WCDMA. deployments since it uses the same network backbone. Trial TD-SCDMA networks and 3G services are now established in various cities in China China is a geographical area encompassing multiple territories, under two states. You may be looking for:
With the addition of the SoftFone-LCR+ chipset to its 3G product portfolio, TD-SCDMA handset manufacturers have the option to choose between a single platform for either voice-centric or cutting-edge multimedia capable handsets. The SoftFone-LCR+ chipset provides support for enhanced multimedia functions such as 3 megapixel cameras, USB USB
in full Universal Serial Bus
Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. , multi-format audio encode/decode, as well as advanced video capture and playback, and stereo audio codecs. The chipset supports video algorithms such as MPEG (Moving Pictures Experts Group) An ISO/ITU standard for compressing digital video. Pronounced "em-peg," it is the universal standard for digital terrestrial, cable and satellite TV, DVDs and digital video recorders (DVRs). 4, H.263 and H.264 for screen sizes up to QVGA (Quarter VGA) A screen resolution of 320x240 pixels, which is used on handheld devices. Although 320x240 seems half the 640x480 VGA resolution, the "quarter" comes from the total number of pixels, which is one fourth the number (320 times 240=76800; 640 times 480=307200). ; stereo audio codecs including MP3, AAC+, WMA and others; and it offers 128-voice MIDI ringtones - all handled in software. The chipset also supports full "boot from NAND (Not AND) A Boolean logic operation that is true if any single input is false. Two-input NAND gates are often used as the sole logic element on gate array chips, because all Boolean operations can be created from NAND gates. See flash memory. " capability, so that cost-effective NOR-less designs for feature phones are possible. The chipset enables dual-mode TD-SCDMA/GPRS operation and achieves full 384 kbps 3G performance, enabling faster download speeds, video streaming, video telephony and Web browsing capabilitiesacritical requirements in supporting the migration to 3G wireless networks in China. In addition, the SoftFone-LCR+ chipset features the industry's highest performance RF transceiver, Othello[R]-W, which offers the lowest call drop rates and best sensitivity available.
"Today's announcement of our second-generation SoftFone-LCR chipset strengthens our technology offering and clearly demonstrates Analog Devices' commitment to accelerating the development of TD-SCDMA technology," said Christian Kermarrec, vice president, RF and wireless systems, Analog Devices, Inc. "As China migrates to 3G networks, our expanded technology offering is well positioned to address the wide-ranging needs of carriers and handset manufacturers - some of whom will choose to transition existing customers, focusing on voice-centric features, while others will immediately target the high-end of the market with advanced audio and video capabilities. The performance and functionality of the SoftFone-LCR+ chipset ensures that users will be able to have a multimedia-rich 3G experience on the new networks"
According to Michael Thelander, CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of Signals Research Group, LLC, "Analog Devices' expanded portfolio of TD-SCDMA silicon solutions is a positive indicator for both the company and for the continued development of TD-SCDMA as a wireless standard that can support a wide range of applications and end users. As TD-SCDMA trials move into the next phase toward full commercialization, this announcement is another indicator that ADI is well-positioned to benefit from the ramp of the burgeoning 3G standard."
About the SoftFone-LCR+ Chipset
The SoftFone-LCR+ chipset supports all the critical functions required to build a TD-SCDMA handset, including the baseband signal processing and control, analog-interface functions and radio. It is based on the popular RAM-based SoftFone architecture also used in Analog Devices' GSM/GPRS, EDGE and W-CDMA chipsets. ADI's SoftFone-LCR+ dual-mode chipset consists of five chips, including the AD6903 digital baseband processor that utilizes the company's Blackfin Processor achieving 260 MHz along with an ARM9 microcontroller, to perform both the communications and audio/video signal processing tasks in a media-rich handset. The software-based approach of the SoftFone architecture enables terminal developers to maintain maximum software flexibility. Additionally, the SoftFone-LCR+'s AD6857 Stratos-T analog baseband and power management IC provides a full set of audio features, as well as efficient power management. 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.
In addition, the SoftFone-LCR+ chipset includes the Othello-W direct-conversion radio transceiver, offering solid performance and flexibility for either LCR time division duplex Time division duplex
Time division duplex (TDD) is the application of time-division multiplexing to separate outward and return signals. It emulates full duplex communication over a half duplex communication link. (TDD) or W-CDMA frequency division duplex (FDD) terminals. For dual-mode operation, the chipset adds the award-winning Othello-G transceiver, which enables the world's smallest GSM/GPRS radio.
The SoftFone-LCR+ chipset is sampling now and volume production is expected to begin in spring, 2007.
