Off-the-shelf, Low Cost Devices Augment ASIC/FPGA Implementations Providing CPRI Standard between Radio Cards and Baseband Processing Modules
2月 26, 2008
SAN JOSE, Calif., February 26, 2008 – IDT® (Integrated Device Technology, Inc.; NASDAQ: IDTI), a leading provider of essential mixed signal semiconductor solutions that enrich the digital media experience, today announced a new family of common public radio interface (CPRI)-based functional interconnect chip (FIC) solutions. These products, which bridge adjacent standards within the wireless infrastructure, will reduce development time and cost and enable developers of base station architectures to more readily meet the needs of the rapidly evolving wireless market sector. These FIC solutions are the first such devices optimized to allow the common CPRI standard to span the interface between the wireless radio card and a Serial RapidIO-enabled base band processing system.
With the IDT family of FICs, system architects are able to offload the translation and connection tasks from the current alternatives – typically an ASIC or FPGA- thus reducing design development time and risk along with providing significant cost savings.
“In order to meet the ongoing consumer demand for advanced wireless services, such as mobile video, while maintaining competitive pricing and reducing development time, wireless infrastructure OEMs need devices which address a variety of standards,” said Ramesh Kumar, world wide marketing director for Texas Instruments' Wireless Baseband Infrastructure Group. “These types of functional interconnect chips, coupled with TI’s single- and multicore digital signal processors are a cost effective means for extending the RapidIO and CPRI standards that enable the further delivery of cost-effective and value-added services to the telecommunications market.”
CPRI is the standard developed and adopted by leading wireless infrastructure companies to provide a common interface that allows system designers flexibility to optimize base station modules independently to meet the fast-paced performance enhancements demanded by the wireless market. The IDT family consists of two devices: a CPRI to serial RapidIO device for baseband processing systems and a CPRI to TDM (time-division multiplexing) interface device for radio card applications. The two devices together provide IDT customers with a complete, off-the-shelf, end-to-end CPRI base station solution enabling faster time-to-market for both initial system development and performance enhancements. Each device has three independent CPRI ports that are compliant to the CPRI 2.1 specification, providing a wide range of popular distributed base station architectures including chain, tree, and mesh topologies.
“The FIC solutions complement our industry-leading portfolio of RapidIO solutions, the pre-processing switches, the central packet switches and the 10G Serial Buffer. These newest devices benefit our customers and the markets they serve because they not only bridge all adjacent standards – a first in the wireless infrastructure - but they also reduce or eliminate the need for costly ASIC and /or FPGA devices,” said Thomas Brenner, vice president and general manager for the IDT Flow Control Management Division. “At IDT one of our goals is to help reduce system costs within the wireless infrastructure, and we do that by breaking down bottlenecks and opening up the ability to use standards. We want our customers and their customers to wirelessly get to whatever information, phone call, and digital media content they want, as fast as they want.”
About the IDT Functional Interconnect Solutions
Like existing members of the IDT family of wireless infrastructure solutions, the FIC devices incorporate in-house third-generation IDT SerDes technology to provide customers with superior flexibility, scalability, performance, and power consumption. Each device contains three CPRI lanes and is CPRI specification 2.1 compliant running at Mbaud performance of up to 2547.6 per lane. The 80HFC1000 CPRI-to-RapidIO device also offers four RapidIO lanes (RapidIO v 1.3 compliant) and is configurable as 1x or 4x port at up to 3.25 Gbaud performance per lane. The 80HFC1001 CPRI-to-TDM FIC offers a 64-bit TDM interface that supports a 150MHz clock rate along with control pins that provide seamless connection to industry standard radio card components.
Pricing and Availability
The 80HFC1000 CPRI-to-RapidIO device is currently sampling to qualified customers and is priced at $20.00 in quantities of 10,000. The 80HFC1001 CPRI-to-TDM device will be sampling in the first half of 2008 and is also priced at $20.00 in quantities of 10,000. Both devices will be available in a RoHS 324-pin BGA package.
