ADC and DAC Clock Phases

Question: I have a SAR6 and a DAC6 hooked up together but I get wrong results.

 

Answer:

Make sure the SAR6 clock phase and the DAC6 clock phase are the same. If one is a normal clock phase, and another is a swapped clock phase, the DAC6 will sample at the wrong clock phase giving strange results. Change the clock phase of either SAR6 or DAC6 and you will achieve a correct output.
