PMC-Sierra Announces Enhanced PALADIN Architecture to Enable Next Generation 3G Wireless Base Stations.Business Editors/High-Tech Writers SANTA CLARA, Calif.--(BUSINESS WIRE)--Feb. 16, 2004 Extending Support for CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. 2000 1xEV-DO, 1xRTT, and WCDMA (Wideband CDMA) A 3G high-speed digital data service provided by cellular carriers that use the TDMA or GSM technology worldwide, including AT&T (formerly Cingular) and T-Mobile in the U.S. Wireless Standards PMC-Sierra, Inc. (Nasdaq:PMCS PMCS PMC Sierra (stock symbol) PMCS Project Management Control System PMCS partial mission-capable, supply (US DoD) PMCS Preventive Maintenance Checks & Services PMCS Professional Military Comptroller School ) today announced enhancements to the PALADIN(R) family of digitally-based processors used in wireless base transceiver stations (BTS BTS - Bug Tracking System ), the equipment required to link wireless handsets to voice and data networks. The enhanced PALADIN architecture incorporates new features to simplify the design of 3G wireless base stations for WCDMA and CDMA2000. Notably, the updated PALADIN architecture now supports 1xEV-DO, the newest generation of CDMA2000 technology. In Asia, CDMA2000 1xEV-DO is already being used for videoconferencing on wireless handsets. PMC-Sierra's new PALADIN architecture enables OEMs and module vendors to build the next-generation BTS today. "Our 2G, 2.5G, and 3G CDMA customers in Asia, Europe, and North America can seamlessly upgrade their existing BTS systems with our latest PALADIN architecture and significantly reduce developmental time and costs," said Bill Richardson, manager of Strategic Marketing, for PMC-Sierra's Service Provider Division. "Since our PALADIN processors are designed to accept digital baseband signals directly, as required by new industry interoperability specifications, system vendors deploying the PALADIN architecture will have a head start in implementing emerging standards such as OBSAI and CPRI CPRI Common Public Radio Interface CPRI Computer-based Patient Record Institute CPRI Central Power Research Institute (India) CPRI Central Potato Research Institute (India) ." PMC-Sierra's third generation PALADIN architecture utilizes digital pre-distortion (DPD DPD Department of Planning and Development DPD Dihydropyrimidine Dehydrogenase DPD Dead Peer Detection (Cisco) DPD Division of Parasitic Diseases (US CDC) DPD Dominant Wave Period DPD Drug Product Database ) technology to improve power efficiencies by more than 50 percent over traditional analog feed-forward solutions, providing substantial OpEx savings for wireless carriers. In addition, DPD technology eliminates many complex analog components from the base station systems. By replacing these expensive analog components with simple and compact digital circuitry, OEMs can reduce CapEx today and take advantage of Moore's Law to realize additional savings in the future. Integrating Enhanced PALADIN Features The enhanced PALADIN architecture uses the new PALADIN 10/15 Release 03 Firmware. The firmware includes extended support for CDMA2000 1xEV-DO and Automatic Gain Control (AGC AGC Automatic Gain Control AGC Automotive Glass Cartridge (fuse) AGC Associated General Contractors AGC Associated General Contractors of America AGC Atypical Glandular Cells AGC Attorney-General's Chambers ) to improve linearization In mathematics and its applications, linearization refers to finding the linear approximation to a function at a given point. In the study of dynamical systems, linearization is a method for assessing the local stability of an equilibrium point of a system of nonlinear differential performance and reduce cost and time in the factory. A user-configurable training signal also has been incorporated into the firmware that eliminates the need for factory test equipment and extra circuitry to initialize To start anew, which typically involves clearing all or some part of memory or disk. the PALADIN device's compensation parameters. Using the internally generated signal has the added advantage of reducing factory training time. PMC-Sierra's PALADIN Product Family The PALADIN family includes the new PALADIN 10/15 Release 03 Firmware, PM7800 PALADIN 10, PM7815 PALADIN 15, and PM7819 PALADIN Waveshaper(TM) devices (see Figure 1). All PALADIN devices support both WCDMA and CDMA2000 technology and work seamlessly together. The PALADIN 10 is suitable for up to 2-carrier WCDMA and up to 8-carrier IS-95/CDMA2000 systems. The PALADIN 15 is suitable for up to 3-carrier WCDMA and up to 12-carrier IS-95/CDMA2000 systems. The PALADIN Waveshaper performs digital multi-carrier combining and crest-factor reduction optimized for WCDMA and CDMA2000 systems. Availability and Customer Support The PALADIN 10/15 Release 03 Firmware is now released to full production. The firmware license is included with the purchase of the PM7800 PALADIN 10 and the PM7815 PALADIN 15. The PALADIN 10/15 Release 03 Firmware datasheet is available at www.pmc-sierra.com/products/ or www.pmc-sierra.com/wireless.
