    Thread Summary
    
                The user is implementing AD9629 capture with an FPGA and facing issues with negative differential input voltages, where the ADC output appears offset by 2^11. The final answer suggests checking the FPGA design for unintentional offsets and experimenting with DCO-to-Data timing adjustments. The user confirms SPI communication and has tried changing the timing without success. The AD9629 datasheet and integrated logic analyzer were used for troubleshooting.

    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.
