Lance, I am checking into this bit 1 issue you are reporting. In the mean time, can you run a NCO test that will verify your DAC is processing the SYSREF input properly? To do this, follow the instructions attached. When the DAC stops working, was the input data ever turned off or sent as a constant value for a long period of time? What is the status of the SYNC signal from the DAC when there is no output? Can you send me your register settings? Are any other errors reported?
