I have some issues with your ADC evaluation board AD9627-150EBZ (https://www.digikey.es/product-detail/es/analog-devices-inc/AD9627-150EBZ/AD9627-150EBZ-ND/1762652).
Namely, I am driving the board with the following signals (please find the pictures attached): input.jpg, as the analog input signal, and clk. jpg, as the clock signal for the ADC. At all digital outputs I have similar response, some type of noise without any correlation with the input signal, as shown in response.png. Even with the 0 V analog input I have similar response. I am very confused with this response since the EVB is new. Please let me know if you have any idea what could be the reason for this issue.
Any piece of advice from your side will be highly appreciated. Thank you in advance!
