Vishay Siliconix Releases New 20-V and 30-VP-Channel Power MOSFETs With Industry’s Lowest On-Resistance

The devices will be used as the adaptor switch and for load switching applications in notebook computers and industrial/general systems. Adaptor switches (switching between the adaptor/wall power and the battery power) are always on and drawing current. The lower on-resistance of the Si7135DP and Si7633DP translates into lower power consumption, saving power and prolonging battery life between charges. [Read more...]

 

Infineon Presents Complete ADSL2+/VoIP and DECT Residential Gateway

09.10.2006 18:30 - Source: Infineon Technologies
Munich, Germany, October 9, 2006 – Infineon Technologies today introduced a wireless broadband integrated access device (IAD) reference design for Digital Home Networks. The new design is based on Infineon’s IAD-on-a-Chip solution, the Danube, which combines an ADSL2/2+ transceiver, a 32-bit MIPS CPU, a VoIP co-processor and two integrated codecs. Infineon’s IAD reference design also features 802.11n WLAN connectivity based on the draft 1.0 specification, and a low-power Digital Enhanced Cordless Telecommunications (DECT) base-station that provides a robust and reliable solution for wireless phone calls over VoIP. This complete hardware/software solution is intended to help companies to rapidly develop broadband IADs and residential gateways that support multiple wireless electronic devices and multiple cordless handsets via a single ADSL2+ broadband connection.

“Having a turnkey reference design frees system manufacturers from dealing with basic technology integration, and allows them to focus on product customization and feature set,” said Alex Green, Research Director, Access & Connectivity IMS Research. “To this end, Infineon’s new reference design not only saves its OEM customers precious time-to-market, but also allows them to differentiate themselves from the competition.” According to IMS Research the market for residential IADs will grow from around 6 million unit shipments in 2006 to around 20 million in 2010. This represents an annual average growth rate of 26% and a growth of 212% over the five year period.

“Infineon is committed to building comprehensive and innovative IAD platforms and system solutions that can continuously provide better value to our customers,” said Christian Wolff, Senior Vice President of the Communication Solutions Business Group and General Manager of the Wireline Access Business Unit at Infineon. “With our complete reference design solutions we provide our customers with a competitive advantage by enabling them to reduce design efforts and gain faster time to market,” he added.

Infineon’s ADSL2+ Residential Gateway reference design is based on the company’s advanced semiconductor solutions and Linux-based application software. Residential gateways based on the Infineon design will enable advanced services such as IPTV, video on demand and online gaming. Integrating DECT into the design will allow users to enjoy low-cost VoIP services via a cordless digital phone which is economic, provides excellent coverage and Telco-grade voice quality. Users will also enjoy wireless home networking with an 802.11n access point that optimized for whole home coverage with peak throughput levels of 150 to 180 Mbps.

About Infineon’s ADSL2+ IAD

Infineon’s Residential Gateway reference design consists of the following components:

Danube: Infineon’s single-chip solution comprises an ADSL2/2+ transceiver, a 32-bit MIPS CPU, a VoIP co-processor and two integrated codecs.  With unparalleled CPU power, hardware acceleration, USB 2.0 Host interface and integrated VoIP telephony, the single-chip device supports full 24 Mbit/sec ADSL2+ data rates for advanced media services, including IPTV, and provides headroom for additional applications.  

DECT Step 8: Infineon’s DECT solution provides a robust and reliable technology for wireless phone calls over VoIP. Already proven in base-band and handset applications, DECT makes for long loop-lengths (better coverage) with excellent voice quality. DECT also allows for lower bill of material (BOM) and much lower power consumption of the handset, resulting in lower system costs.

Spinacer software suite: Spinacer is a software suite for a wide range of broadband CPE applications based on Infineon’s semiconductor solutions. Based on Infineon’s embedded Linux distribution, Spinacer reduces the memory capacity by up to 60 percent depending on the application, while offering maximum flexibility. Spinacer’s modular architecture with easy-to-combine building blocks provides system designers the flexibility to choose the exact software functionality they require.

WLAN 802.11n: The Infineon residential gateway design takes advantage of 802.11n solutions based on the draft 1.0 specification. 802.11n chips are optimized for whole home coverage with peak throughput levels of 150 to 180 Mbps and significantly increase throughput of legacy 802.11g and 802.11a/g products at extended ranges and greater reliability.
