Part Number: ADC12DJ3200EVM

Tool/software:

Hi,

I am feeding a CW signal from a clean source, but the ADC output is noisy at times, as shown in the attached screenshot. Could you please help me obtain a clean output signal from the ADC? What could be the issue?

Hi Kumar,

Are you using our DJ3200EVM & and FPGA dev kit or is this your own design?

We need more context in order to help you.

Hi Kumar,

Can you send me a detailed diagram of your test setup?

Also pics may help too.

The issue may be in the HW setup. So the more details the better to help troubleshoot the issue.

Regards,

Rob
