IDT's Optimized CPRI Solution Addresses Rapidly Evolving Wireless Market

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.
