AD9629 Read

Hi,

I am new to reading ADC. I want to use AD9629 in my design. And i want to read this with FPGA. How can i handle it? Where should i start when writing the VHDL code? What are the things i should be aware of?

Best regards.

  • Hi Harun,

    You should have seen some difference in your captured data when you changed the DCO-data timing. Did you see any change? How many different values did you try?

    Earlier in this thread you wrote that CSB is connected to DRVDD, which is why I thought you did not have SPI communication. Is CSB now being driven by a SPI controller of some sort?

    I'm sorry but at this moment I do not have more ideas for you to try. As an ad hoc solution you might have to subtract 2^11 from your result when MSB = 0.

    Thank you.

    Doug
