Anybody can help to answer this question?
In my system, I need use AD9833 to be synchronous with another signal source, or with a constant phase(same frequency).
In the specification, AD9833 use the soft code to reset the DAC out. But how to control the command tranfer time accurately?
Can I control the DAC output in the following way?
step1: stop the MCLK;
step2:set the RESET bit=1 via SPI;
step3: Configure all other registers with SPI interface.
step4: set the RESET bit =0 via SPI;
step5: enable the MCLK to operate the AD9833;
question1: is it the right way to start the AD9833 accurately?
question2: after step5, is there still 8/9 MCLK cycles delay to see the DAC's change?
thanks a lot
Merry Christmas and Happly New Year!
