DS90UB953-Q1: Low temperature problems

Hi Colleagues,

A customer has issues with certain batches of devices some of them do not pass their test at low temperature. Could you give some information about the differences between these devices with the following markings and let me know if there is a reason for the different performance they see?

Thanks a lot for your help!

    Hello,

    I see you are pointing to the device as being the issue here but in the table you provided it looks like one set is using coax and one is using STP.  Are we certain that the cause of the issue is the device?  Can we swap the devices, keep everything else the same, and verify that one works over the other?

    Regards,

    Nick
