ADC12DL500: Using ADC12DL500 on ADC12DL3200EVM Development Board

Part Number: ADC12DL500
Other Parts Discussed in Thread: ADC12DL3200EVM

Tool/software:

Hello,

I need a development board that includes the ADC12DL500 ADC chip.
During my research, I came across the ADC12DL3200EVM evaluation board.

The Gerber and design files for this board have already been shared. I believe that if I manufacture the board and mount the ADC12DL500 ADC chip on it, it should work.
According to the ADC12DL3200EVM User Guide, all SPI register configurations for the ADC are done via USB using the HSDC Pro software.
I also own a Xilinx AC701 FPGA development board. However, the FMC interface of the ADC12DL3200EVM is not compatible with the AC701's FMC connector.

I have two main questions:

  • If I mount the ADC12DL500 onto the custom-built ADC12DL3200EVM board, will I still be able to configure the device using HSDC Pro software via USB?
  • I am planning to design an adapter board to make the FMC output of the ADC board compatible with the AC701. Would such a board introduce any signal integrity issues, particularly for the LVDS lines?

Any suggestions or experiences regarding this would be greatly appreciated.

    Hi Enes,

    You can develop your own spi interface and/or use the FPGA to program the ADC device. You don't need to use a USB or HSDCPro SW to capture the data.

    If you layout your interposer board incorrectly, then yes, there could be issues with signal integrity, etc. Make sure you use good SI practice when laying out 100ohm diff pair LVDS traces.

    Regards,

    Rob

    Hello, thank you for your quick response.

    Developing a new SPI interface would be quite time-consuming.
    However, is it still possible to use the HSDC Pro software just to perform the SPI configuration?
    If the answer is no, do you have any guidance or documentation for developing a USB-to-SPI interface for this purpose?

    Thank you.

    Hi Enes,

    HSDCPro SW captures the data from the our TSW data capture boards. It does not have anything to do with the USB or spi interface.

    The ADC or DAC device will have a specific GUI SW program for programming the spi interface thru a USB connector on the ADC/DAC EVM itself.

    If you use the same USB/FTDI circuit on your customer board, you can certainly use the ADC GUI to program and configure the device.

    Regards,

    Rob

    I thought that data capture and SPI configuration were handled through a single interface. I’ve now learned that the ADC GUI is a separate interface.

    Thank you for your support.
