What is the reason for a 250MHz minimum frequency for SYSCLK on the 9912 DDS? I would like to run it at 100MHz or lower.
It seems peculiar that it would have a lower frequency limit. What sets the lower frequency limit? Thanks
The device should work running lower than 250 MHz System Clock. Part of the reason it is not specified below that frequency was to reduce the effort needed for evaluation; it was deemed likely that folks needing to run slower would look to some of the lower speed DDS devices available (e.g. AD9954)
