Hi to all in this forum.
I am using the magic number to control my AD9850 DDS and it worked very well for years.
Now I am going to use the AD9912 DDS and I will like to calculate or to have the magic number to control it : the ref clock is 100 MHz internally multiplied by 10 so the real ref should be 1 GHz. I am using PBP 2.50 and longs.
I understand that the 9912 has a 48 bit tuning word (FTW): what will be the limitations in this case ?
Thanks in advance for any assistance .
regards,
Ambrogio
