IDT has announced a new family of common public radio interface (CPRI )-based functional interconnect chip (FIC) solutions that bridge adjacent standards within the wireless infrastructure. 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 development time and risk whilst providing significant cost savings.

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 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 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. Both devices will be available in a RoHS 324-pin BGA package.
