Hi
I need to output the square waveform output from AD9834.
The AD9834 datasheet mentions to connect this comparator to the SIGN BIT OUT pin after filtering the sinusoidal output from the DAC.
The MSB from the NCO can be output from the SIGN BIT OUT pin and it is useful as a coarse clock source.
Which is More accurate？
Why does MSB from the NCO is coares?
Best regards

It depends on the ratio between MCLK and the tone frequency. When the waveform frequency increases there are fewer samples per period, which eventually results in a variable duty cycle that causes jitter…
Shouldn't be the jitter gone away if the DIV2 function enabled and the MSB frequency is divided by two? In my experience the "jitter", the uneven periods are still present when divided by 2.…
