PMC-Sierra Announces Availability of Complete CPRI Reference Design for Standards-Compliant Third Generation Wireless Base Station Interconnects.SANTA CLARA Santa Clara, city, Cuba Santa Clara (sän`tä klä`rä), city (1994 est. pop. 217,000), capital of Villa Clara prov., central Cuba. , Calif. -- PMC-Sierra's solution enables the rapid development of low-cost, CPRI-compliant interfaces for distributed antenna systems 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 the immediate availability of a complete Common Public Radio Interface (CPRI CPRI Common Public Radio Interface CPRI Computer-based Patient Record Institute CPRI Central Power Research Institute (India) CPRI Central Potato Research Institute (India) (TM)) reference design that provides Base Station vendors with a significant time to market advantage by allowing low-cost prototype CPRI solutions to be quickly developed and validated. PMC-Sierra's offering is the industry's most complete standard product solution and provides a clear path to higher integration and lower cost CPRI solutions through the migration to a single chip ASSP (Application Specific Standard Part) An ASIC chip that is designed as a generic device for a particular market. Whereas an ASIC is typically used only by its creator, ASSPs are used by many different companies in the design of their products. See ASIC. solution for production systems. The PMC-Sierra CPRI solution is already being deployed by major OEMs and has been successfully tested for interoperability with other CPRI implementations. It meets all the most demanding CPRI requirements including accurate delay calibration and high-quality clock recovery. With the PM7815 PALADIN(R) Digital Correction Signal Processor already shipping in production OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and systems, PMC-Sierra has further solidified its role as a key vendor for 3G Wireless Base Station silicon. Providing the Complete Solution PMC-Sierra's complete CPRI reference design is comprised of three main components -- --10 Gigabit Ethernet An Ethernet standard that transmits at 1 Gbps. Used mostly to connect high-end workstations and servers as well as for network backbones, Gigabit Ethernet transmits full duplex from point to point using switches and half duplex in a shared environment (CSMA/CD) using a hub. Serializer/Deserializer (SERDES See serializer/deserializer. ): PMC-Sierra is leveraging the superior signal integrity of its PM8358 QuadPHY 10GX SERDES device to implement the CPRI physical layer. The QuadPHY 10GX provides four low-jitter serial transceivers that are fully compliant to the CPRI electrical specifications and support simultaneous operation at all CPRI line rates. In addition, the QuadPHY 10GX supports a broad range of applications for high speed serial links such as XAUI XAUI 10 Gigabit Attachment Unit Interface XAUI Extended Auxiliary Unit Interface XAUI XSBI Attachment Unit Interface (IEEE 802.3ae) XAUI Ten Gbps Attachment Unit Interface , OBSAI RP3, Serial RapidIO, PCI Express, and Infiniband 4X. --CPRI Framing: The CPRI data link layer framing, delay calibration and control sub-channel insertion/extraction functions are performed separately in an FPGA (Field Programmable Gate Array) A type of gate array that is programmed in the field rather than in a semiconductor fab. Containing up to hundreds of thousands of gates, there are a variety of FPGA architectures on the market. device. --CPRI Frequency Synchronization: Discrete components are used to implement a circuit for cleaning and de-jittering a high stability master timing reference from the recovered serial line clocks. "The availability of standard product solutions that meet interconnect specifications such as CPRI addresses the growing demand for standardized wireless base station architectures," said Bill Richardson, marketing manager for Wireless Products at PMC-Sierra. "By delivering these solutions, we are enabling our end customers to reduce their development cycles, achieve interoperability, and lower their time to market and overall development costs." Availability PMC-Sierra will demonstrate its complete CPRI reference design at the SuperComm show in Chicago, Ill on June 7-9, 2005. The PMC-Sierra CPRI solution is immediately available for evaluation to qualified customers. For further information, please email mailto:cpri@pmc-sierra.com.
