I will use AD7792 with External clock.
When changing MCLK, what would influence the special quality（without output data rate and notch frequency )?
I'd like to estimate mainly by a product substrate.
Apologies. But can I clarify your question? Do you mean what would be the effect when changing master clock other than the nominal? When the MCLK frequency is changed, the output data rate will scale with the applied clock and changing the output data rate will also affect the filter notches. So, if the output data rate is 16.7sps when a 64 kHz master clock is used, the output data rate will change to 16.7 x (60/64) = 15.66 sps when the master clock is changed to 60kHz. Similarly, a notch at 50 Hz and 60Hz (64 kHz master clock) will move to 46.87Hz and 56.25Hz (60 kHz master clock).
Can you also clarify this "I'd like to estimate mainly by a product substrate"
What do you mean by this and it's relation with the MCLK question?
Thank you Very much.
"Can you also clarify this "I'd like to estimate mainly by a product substrate""Sorry,this mean i will check my bord what would influence.
Okay. Hope that helps. If you have any further questions just let us know.
