Questions About Potential SDR and DSP Evaluation Boards


My name is Todd Christiansen, and I am an undergraduate Electrical Engineering student at University of Colorado, Colorado Springs. I'm currently involved in a Senior Capstone project which involves building a software-controlled channel simulator for use in a radar simulation lab.
The device will take an analog input signal (either 20.5 MHz or 23.5 MHz with 1 MHz bandwidth), and perform time delay and phase shift as instructed on the signal before outputting it as an analog signal. We have looked into a number of DSP and SDR options, but none have had suitable evaluation boards for our needs. The basic input / output needs of our board are as follows:
 - Analog SMA in (followed by minimum 12-bit ADC)
 - RJ45 ethernet for control signal
 - RJ45 ethernet (configured as LVDS with two pins forming a 60 MHz global clock and two pins forming a sync pulse that will occur roughly every 50 milliseconds)
 - Analog SMA out (preceded by minimum 12-bit DAC)
The biggest stumbling block at this point is the LVDS ethernet connection. Many evaluation boards have onboard ethernet, but very few have a PHY configured for receiving and interpreting LVDS. We also noticed that many of the DSP evaluation boards from ADI were configured for audio input and output rather than SMA.
Are there any SDR or DSP evaluation platforms (along with any peripherals for the LVDS needs) that might satisfy our requirements? We have found a few FPGA options, but our preference would be to work with something that doesn't rely heavily on Hardware Description Language if at all possible.
Thank you for your time, and I hope to hear from you soon.

    Thanks for your interest in Analog Devices Processors.

    Analog Devices' SHARC® processor family dominates the floating-point DSP market with exceptional core and memory performance and outstanding I/O throughput. With multiple products variants and price points, SHARC brings real-time floating-point processing performance to many applications where dynamic range is key. Latest products provide leading performance/power efficiency and advanced connectivity with an integrated ARM® core.  

    You can get more information about SHARC processors in the below link:

    New multi core processors are the latest in a growing series of high-performance, power-efficient, real-time platforms that deliver greater than 6 giga-floating-point operations per second using two enhanced SHARC+ cores and advanced DSP accelerators (FFT, FIR, IIR).

    The ADSP-SC5xx processors have the multi-core SHARC+ with ARM in the architecture. Please refer the below link for more details:

    Analog devices Blackfin® 16-/32-bit fixed point embedded processors offer software flexibility and scalability for convergent applications: multiformat audio, video, voice and image processing, multimode baseband and packet processing, control processing, and real-time security.

    The ADSP-BF60X and ADSP-BF70X are the new processors in Blackfin family. The ADSP-BF60x processors are the Dual-Core processor up to 1GHz with Hardware Support for HD Video Analytics. The ADSP-BF70x processors are the latest Low Power 400MHz Blackfin+ embedded processor with 1MByte L2 SRAM & DDR2/LPDDR Interface.
