Software Defined Radio (SDR) OMAPL-138-based Hardware & Software Reference Design


Design files


Software Defined Radio (SDR) is a popular application within the wireless infrastructure market.  This hardware reference design, leveraging the real time signal processing of the TI DSP and its Universal Parallel Port (uPP), along with TI ADC and DAC, offers SDR algorithm developers a quick platform to enable quick development and demonstration of algorithms and solutions.

  • Offers a Software Defined Radio (SDR) platform is based on the MityDSP-L138F System on Module (SOM) from Critical Link, LLC that provides a hardware and software framework designed to accelerate the development  of SDR applications.
  • Includes both a Xilinx Spartan 6 FPGA and a TI OMAP-L138 dual core processor, as part of Critical Link’s production-ready MityDSP-L138F System on Module (SOM).
  • Offers Source design files for the base Industrial Input and Output card, the ADC board, and the DAC board
  • Offers an easy interface to OMAP-L138-based SOM.
  • Offers ARM based GUI software.
  • Offers sample uPP software.
  • Supports standard peripherals supported including ENET, USB, SATA and LCD
