AD9144 - Meaning of I TO Q SWAP

Hello,

 

From the Rev 0 to the Rev A datasheet for the AD9144 the I to Q Swap definition migrated from swapping the I and Q data paths to routing the I data path to the Q DAC presumably keeping the I DAC on the I data path (this presumption has been confirmed by measurement). Can someone please explain to me what is the use of this feature?


In my experience swapping the I and Q data paths is a very useful feature but doesn't seem to exist on this part.
