ADS5407EVM: Problem about ADS5407EVM. Does ADS5407EVM module board support dma function and memory buffer without go through computer?

Part Number: ADS5407EVM

Hello,
I have some questions about ADS5407EVM.
I have bought ADS5407EVM module board and wonder if it has dma function and memory buffer inside?
Since I don't want the sampling path to go through the computer, and I can't find any solution about it in ADS5407EVM datasheet.

In my previous testing, I tried to use ADS5407EVM to sample analog signal in 500MHz and got the adc output data by MCU.
But the testing result is not that good, and I wonder if it is because the dma function and memory buffer is not equipped in the board.
If ADS5407EVM module board not have "buffer function", can you tell me any product in TI can help me to do this work with ADS5407EVM?
Or can you provide any information about this work in hardware soultion.
Thank you for your helping.

Best,

TYLiu

    Hi TY Liu,

    The ADS5407 is a straight pipeline based ADC. It is typically meant to transfer data in LVDS fashion directly to the FPGA. The ADC itself have no memory element like DMA and memory buffer to "hold" the data. It relies on the FPGA to do all the data interface and baseband processing (basically all the other digital heavy lifting).

    You may use the ADS5407 EVM with the TSW1400EVM FPGA based capture card and HSDC PRO software for FFT processing.

    See the following user's guide for detail:
