Spectrum Offers Digital IF Interface Module, Reference Design for SDR

11/17/2004 - Spectrum Signal Processing Inc. (NASDAQ: SSPI / TSX: SSY) announced the availability of the TM1-3902 digital Intermediate Frequency (IF) interface module and reference design kit for its industry leading SDR-3000 software defined radio platform. The TM1-3902 is targeted at customers who require their own custom digital IF interface between Radio Frequency (RF) front-ends and Spectrumís Software Communications Architecture (SCA)-enabled SDR-3000 products. The module supports a sustained 1280 Megabytes per second full-duplex interface suitable for digitized signals having bandwidths in excess of 500 MHz being sampled at rates in excess of 1 GHz. The TM1-3902 can also be used to support various multi-channel architectures such as those required for direction finding or smart antenna applications.

The TM1-3902 serves two functions. First, it can be used as-is to provide a digital IF interface to SDR-3000 products. Developers may connect third-party products supporting a digital interface directly to the fully-documented daughter sites on the TM1-3902. These daughter sites support the digital IF interface integrated in RF solutions from Digital Receiver Technology, Inc. (DRT) and DRS Signal Solutions, Inc.. The second function is that of a complete reference design package consisting of documentation, source code, hardware pin-outs, schematics and firmware to enable customers to create their own modules based on the digital IF interface. Test code showing full-speed operation of the interface to the SDR-3000 channelizer is also supplied.

ďThe TM1-3902 further enhances the ability of the SDR-3000 to address a variety of different and very demanding signal processing problems in signals intelligence, military satellite communications, and electronic warfare,Ē stated Mark Briggs, Spectrumís Director of Marketing. ďWe expect the TM1-3902 reference design to help our customers realize significant cost and time savings throughout their development and deployment cycle, by facilitating the use of a single platform to address multiple applications.Ē

The TM1-3902 incorporates a user-programmable Xilinx® Virtex-II ProTM XC2VP30 field programmable gate arrays (FPGA) that allows users to tailor the digital IF interface to their specific application needs. The XC2VP30 connects to two daughter-site connectors that can be used directly for external interfacing. The daughter-site interfaces are the same as those present on Spectrumís ePMC-FPGA and ePMC-8120 modules, and support Spectrumís LINK-IF interface protocol, which has been adopted by DRS Signal Solutions, Inc. for use in their SI-9136A receiver, and is compatible with the Digital IF interface of the DRT RFT2 receiver. The XC2VP30 interfaces to other logic implementing the SDR-3000 TM1 digital IF interface bus. A control interface is provided to allow the embedded controller on the SDR-3000 channelization card to load and read/write the XC2VP30 using the quicCommTM library that is included.
