Good day to all!
We use the DAC38J82 and it works fine, but when the DAC temperature is more than 45 degrees, errors appear on the JESD204B lines. The number of errors can be different from 2-3 per hour to errors that go constantly. The following errors appear: code synchronization error, 8b/10b not-in-table code error, 8b/10b disparity error, read_error, read_empty.
When there are JESD errors, sometimes SYNC goes to zero:
During normal operation, the SYNC is one:
When the temperature decreases, errors disappear. What could be the problem?
