CommAgility announced today that it has successfully completed interoperability testing of its AMC-2C6670 AMC (Advanced Mezzanine Card) with a MTI Remote Radio Head (RRH) equipped with CPRI (Common Public Radio Interface), as well as with a Xilinx CPRI IP core.

The interoperability tests were carried out using the AIF2 interface of high performance TMS320C6670 and TMS320TCI6618 digital signal processors (DSPs) from Texas Instruments Incorporated (TI) running on the AMC-2C6670. To test with a Xilinx CPRI core, an additional AMC-V6 module from CommAgility was used with an optical SFP+ interface.

Tests were successfully completed up to the maximum DSP AIF2 data rate of 4.9152 Gbaud, which is the CPRI x8 rate. I/Q data transport was tested in various combinations including multiple channels and carrier aggregation. Vendor specific and fast C&M control channels were also tested.

CommAgility's AMC-2C6670 AdvancedMC includes two TMS320C6670 DSPs. The card also provides a Xilinx LX240T Virtex-6TM FPGA for additional I/O and co-processing flexibility. The AMC-2C6670-3AIF variant links 3 of the DSP AIF2 interfaces to SFP+ connectors on the module's front panel, allowing

optical or electrical connection to external RF equipment using the CPRI or OBSAI standards.

Dr. Christian Lanzani, Senior Product Manager at MTI Radiocomp, said: CommAgility has proven that its AMC-2C6670 card is fully interoperable with our CPRI interface, which is an integral part of our RRH offering for both TD-LTE and FD-LTE markets. With instantaneous RF bandwidths in excess of 40

MHz supported by CPRI v.4.2 interface up to 9.8 Gbps our RRH platforms are suited for IMT-Advanced applications including carrier aggregation.

Edward Young, managing director at CommAgility, said, This successful testing proves our latest product family and demonstrates our expertise with the latest generation of DSP processors. This means that customers can use our AMC-2C6670 card with confidence in LTE systems.

CommAgility's DSP expertise and extensive example and library software is available to users of its telecoms and signal processing boards, helping them to bring successful designs to market quicker and more efficiently.
