San Jose, Calif. Integrated Device Technology, Inc. (IDT) has launched a new family of common public radio interface (CPRI)-based functional interconnect chips (FICs). These products, which bridge adjacent standards within the wireless infrastructure, are expected to reduce development time and cost, in part by offloading the translation and connection tasks from the current alternatives, typically an ASIC or FPGA. These FIC devices are said to be the first that are optimized to allow the common CPRI standard to span the interface between the wireless radio card and a Serial RapidIO-enabled baseband processing system.
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 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 offers 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.
Like existing members of the IDT family of wireless infrastructure solutions, the FIC devices incorporate in-house third-generation IDT SerDes technology. Each device contains three CPRI lanes and is CPRI specification 2.1 compliant running up to 2547.6 Mbaud per lane. The 80HFC1000 CPRI-to-sRIO device also offers four sRIO lanes (sRIO v 1.3 compliant) and is configurable as 1x or 4x port at up to 3.25 Gbaud per lane. The 80HFC1001 CPRI-to-TDM FIC offers a 64-bit TDM interface that supports a 150-MHz clock rate along with control pins that provide connection to industry standard radio card components.
Pricing: The 80HFC1000 CPRI-to-sRIO and 80HFC1001 CPRI-to-TDM devices are priced at $20.00 in quantities of 10,000.
Availability: The 80HFC1000 CPRI-to-sRIO device is currently sampling to qualified customers. The 80HFC1001 CPRI-to-TDM device will be sampling in the first half of 2008. Both devices will be available in a RoHS 324-pin BGA package.
