Hi Vincenzo I've discussed this more with a few experts and we have a few theories and some debugging steps to try. 1) It's possible the RBD (receive buffer delay) setting in one of the JESD204B receivers has insufficient margin to handle timing variation across temperature. At a certain point this would cause a brief interruption of the link. Please try increasing the RBD settings by 1 or 2 to see if that has any impact. 2) Are any JESD204B error flags in the receivers set at the time that the error occurs? 3) Do the JESD204B links reinitialize or restart? 4) Are there any alarms being set in the ADC or DAC (ie. i.e. LINK_ALM or REALIGNED_ALM or CLK_ALM in ADC12DJ3200 ) Please note that the ADC alarms may be set initially and should be cleared once the link is up and operating. Best regards, Jim B
