ADSL2+ Chip from Infineon Sets New Standards for Power Consumption and System Costs
With the new semiconductor chip for future DSL central offices, Infineon Technologies is underscoring its leading role in the booming market for the chips that are being used in broadband data networks, emphasizes Christian Wolff, Vice President Communications Business Group and General Manager Wireline Access Business Unit at Infineon. At the beginning of 2005, there were approximately 100 million DSL connections throughout the world. Approximately 40 percent of these connections were added last year. This growth is expected to continue over the next few years. In the process, the new ADSL2+ standard is to replace the current DSL connections soon. With ADSL2+, data can be transmitted at up to 25 megabits per second. This is approximately ten to twenty times faster than the DSL connections that are typically in use today, and it is sufficient to transmit several high-definition television broadcasts, Internet data and inexpensive Internet telephone calls simultaneously.
Less Heat More Connections Within the Same Space
The new GEMINAX PRO ADSL2+ chipset from Infineon offers DSL central offices performance features that are unmatched to date. Power consumption is about 30 percent lower than is the case with conventional chips, and a correspondingly lower amount of heat is produced. Thanks to these features and to the small overall size, it is possible to install the chips in switching systems at much higher densities without requiring any additional cooling. Over all, GEMINAX PRO now makes it possible to install approximately one third more ADSL2+ connections without increasing the amount of cabinet space that is required.
The switched-mode technology that is used in GEMINAX PRO is already being employed widely in portable audio devices (such as MP3 players) due to its extremely low power consumption levels. Through a multitude of technological innovations, Infineons developers have now succeeded in adapting and advancing this technology for broadband applications, although the requirements in this area are much more stringent and the frequency that is used is 100 times higher. The first prototypes for the new chip will be shipped in May, and volume production will begin in autumn 2005.
Infineon Technologies AG, Munich, Germany, offers semiconductor and system solutions for automotive, industrial and multimarket sectors, for applications in communication, as well as memory products. With a global presence, Infineon operates through its subsidiaries in the US from San Jose, CA, in the Asia-Pacific region from Singapore and in Japan from Tokyo. In fiscal year 2004 (ending September), the company achieved sales of Euro 7.19 billion with about 35,600 employees worldwide. Infineon is listed on the DAX index of the Frankfurt Stock Exchange and on the New York Stock Exchange (ticker symbol: IFX). Further information is available at www.infineon.com.
Consisting of a 16-channel ADSL2+ Digital Front End (DFE) and a 4-channel Analog Front End (AFE), with integrated low-power Class D line drivers, the GEMINAX PRO chipset reduces power dissipation, footprint and overall system costs by up to 30 percent, in comparison to other chipsets currently available.Press Photo
