Part Number: ADS52J91

Tool/software:

Hi,

we have a ADS52J91 connected to an Xilinx UltraScale+ Board. We face the issue that the JESD core is stuck
in CGS and doesn't move on the ILA and/or Data mode. Does anyone had such an issue before?

regards

Ben

Thanks for your reply. We already found that the SYNC signal was no correct which causes the issue. Like you mentioned.
