looking for info wrt

(a) on phase truncation spurs sampled data points mapped on to a 32-bit phase
wheel lookup table.

(b) synchronisation pins, SYNC_IN and SYNC_OUT. 

 

Please note for technical support we can provide support with issues that you
may have or query related to the part or part are not interface/working
correctly.

(a) For the Phase wheel/truncation and correlation please look at the
educational technical tutorials paper; A Technical Tutorial on Digital Signal
Synthesis
as in  e.g. page 7, 20 etc. (If not already aware there are also other
interesting one, that may be of interest)   from link

(b)
As a note: synchronising would be similar to previous examples see links below.
I am not sure if timing would be available in what you looking for as this may
reveal the internal structures/architect. As a request i have cc our
productline to see what info they have for public release.

in the mean time please See info below wrt sync.
