14 years ago --- Quote Start --- How can you tell? Do the bits start getting corrupted? --- Quote End --- Yes, data is sent as relatively short fixed size frames with word synchronization pattern at the beginning and frame check sequence (CRC) at at the end of each frame. I run the tests over wide span of temperatures and at certain relatively narrow temperature regions I see both "dotty" data errors and more stable bit slips, typically by two bit positions. --- Quote Start --- How much does your data change? --- Quote End --- On average, there are changes more than 50% of the time. Worst case, ~300 bits without changes and then a short burst at 100% changes, but worst case is extremely rare.
