Is it possible that DCLK is provide at same time as providing CLK at power-up?
Customer provide DCLK at same time as providing CLK at power-up.
Background of this question is the following.
I posted this question for resolving below issue.
My customer sometime has FIFO_err and DLL unlock at power-on reset.
and DAC5681 output sometime has spurious as below picture.
This spurious continues once this situation is out until power-on reset again.
