Analog Devices Unveils Details of Single-Chip Octal ADSL Transceiver With 75 Percent Reduction in Component Count - New chipset to lead industry in port density and low-power dissipation
NORWOOD, Mass., June 21 /PRNewswire/ -- Analog Devices, Inc. (NYSE: ADI - news) today unveiled details of its new Octal-Port ADSL (Asymmetric Digital Subscriber Line) chipset, offering a 75 percent component count reduction from current chipsets. DiamondBack(TM) previewed at Supercomm 2000 in early June, is a fully programmable, multi-mode, eight-channel, single-chip transceiver that enables simultaneous G.Lite and Full-rate ADSL operation.

Designed with the world's best signal processing expertise coupled with industry-leading analog and mixed signal technology, ADI's DiamondBack features unparalleled integration that will quadruple the density of ADSL line cards to as high as 64 ports. With the majority of manufacturing cost of today's ADSL solutions composed of external analog components, decreasing the number of system components, chip placements and connections reduces transceiver and analog component integration significantly reduces bill-of- materials and manufacturing cost by 60 percent over current ADSL systems.
Similar to ADI's previous generation ADSL chipsets, the DiamondBack Octal- Port chipset offers numerous features that safeguard infrastructure investments, increase manufacturers' competitive advantage, and provide manufacturing and design flexibility. Such features include support for all worldwide ADSL standards, widespread field-proven interoperability, and support for next-generation voice over data and video applications.
Diamondback(TM) Delivers Twice the Density of Competitive Octal-port Solutions
Complete ATM interface to line circuitry using Diamondback occupies less than 0.7 square inches per port, significantly less than competing octal-port chipsets multi-mode as well as G.lite optimized chipsets. Power dissipation is projected at an industry-leading 1.15 Watts per port, better than most multi- mode chipsets and equaling G.lite optimized chipsets. The power dissipated by the ADSL transceiver is projected at 350 milliWatts per port.
About ADI's DiamondBack(TM) Octal-Port
DiamondBack is a five component, ATM-to-Line ADSL solution consisting of an integrated octal-port transceiver that includes the analog front end and four dual-channel integrated line drivers, receive amplifiers and attenuators. The chipset, an evolution of ADI's field-proven AD20msp930 and CopperHead(TM) Quad-port chipsets, leverages the same architecture and proven firmware, thereby providing equipment vendors a low risk, time-to-market solution. In addition, ADI's solutions offer certified interoperability with leading ADSL semiconductor vendors, including Alcatel and Texas Instruments. Initial versions of DiamondBack will be available in early 2001. More information is available by contacting Analog Devices.
``We are most satisfied with the level of integration that we have been able to achieve with DiamondBack'' said Jacques Ruch, product line director for broadband communications, Analog Devices. ``DiamondBack offers unparalleled density that no other silicon vendor is able to match, and surpasses manufacturers' expectations of size and power dissipation.''
The World's First Dual-channel Integrated Driver/Receiver to Deliver Full- rate ADSL Signals
ADI is also introducing the world's first dual-channel integrated driver/receiver dissipating a low 800 milliWatts of power per channel for full-rate ADSL signals. The integrated driver/receiver includes the line driver, receive amplifier and attenuator required to deliver ADSL signals to the line without compromising performance. Analog circuitry complexity and component counts are reduced by more than 75 percent. A quad-channel integrated driver/receiver for short-loop, digital loop carrier (DLC) applications dissipating 600 milliWatts per channel, in full-rate ADSL mode, will also be available. Advanced features such as automatic line sensing and power cutback will be added later in 2001.
``Analog signal expertise is critical to ADSL performance'', said Vic Jayasimha, director of business development, broadband communications, Analog Devices. ``The ability to detect the ADSL signal through line noise and deliver it down the line without impairment is crucial. With its world-leading expertise in analog and mixed-signal design, Analog Devices is the only silicon vendor able to deliver highly integrated, small package, high- performance analog technology that allow telecommunications vendors to successfully differentiate their products.''
Simplifying Cost-Effective Voice Over Data and Video Service Deployment Similar to ADI's AD20msp930 and CopperHead(TM) chipsets, DiamondBack has been optimized for voice over data and video transport with each modem supporting multiple dual-latency channels to carry time-sensitive voice, video or data traffic. The chipset supports traditional voice-over-data implementations such as Voice over ATM and Voice over IP. In addition, the chipset supports the recently announced Voice enabled DSL (VeDSL(TM)) that gives service providers a cost-effective means of provisioning multiple phone lines to residential users by eliminating the need for expensive network voice gateways. When combined with Analog Devices' industry-leading Voice over Network (VoN) processors supporting up to 40 simultaneous voice channels, DiamondBack will provide the industry's most cost-effective VoDSL platform. The chipset will also offer simplified software upgrades to boost downstream data rates over short loops to support multiple MPEG-2 high definition video channels.
Standards Compliance
ADI's ADSL chipsets support multiple worldwide ADSL standards including: International Telecommunications Union (ITU) G.992.1 (full-rate ADSL), G.992.2 (lite ADSL) and G.994.1; American National Standards (ANSI) T1.413 issue 2; and European Telecommunications Standards Institute (ETSI) TR328. In addition all chipsets support Annex A (POTS) and Annex B (ADSL over ISDN - Europe) standards. Starting with Diamondback, ADI now extends its standards support to Annex C (ADSL over ISDN - Japan).
