Thanks Henrik for the kind reply on the matter.
On the AD9850 the FTW is computed by the following : FTW = Frequency ** 2251800.
I call magic number the " 2251800" constant.
What will be the constant for the ad9912 DDS?
How could I determine the frequency limitation due to the longs .. etc ?
Thanks again for the assistance.
Regards,
Ambrgio
