Hi All,
I have a question regarding the functionality of the DS90CR288AMTD related to the clock functionality. The issue shows up more frequently at an elevated temperature (53C). The IC is powered, the input clock is 32MHz, and the data lines are also connected. The Power Down signal is asserted and at some point of time I de-assert the Power Down.
It appears that from time to time I do not see the Clock on the output of the SERDES. I would wait for 1.5s and assert the Power Down for a longer time (60s) and de-assert it again. The SERDES would generate the clock most of the time but in few instances this cycle has to be repeated one more time.
Have you come across this before, and if so I'd like to understand the root cause of the issue and potentially if we can screen devices that exhibit this behavior. Thanks in advance for any insight you can provide!
Thanks,
Ethan
