Dear experienced users,
when synchronizing multiple DDS chips, is relevant that the SYNC_OUT of the master device keeps running _after_ the synchronization procedure was successful?
I remember reading somewhere that the SYNC_OUT can be disabled after the sync process but I can't this information anymore.
Does anyone have experience wether it is best to leave the SYNC_OUT running or not? I just want to get rid of all unnecessarily running clocks in my system so I'd like to turn off SYNC_OUT but I'm not sure if this might get me into some kind of unknown trouble ...
Best regards and thanks in advance !!
I also have a followup-question:
The datasheet says that CFR2 and CFR2 _must_ be set to "1" for the SYNC_OUT generator to be active. And that if CFR is cleared, the SYNC_IN signal will be put out on SYNC_OUT (Page 34).
Yet table 18 says that if CFR is "1" the SYNC in signal is routed to SYNC_OUT ...
Is this contradictory or am I getting somethin wrong?
Maybe someone can clear that up for me.
