I think the DDS is implemented inside the PLD.

Sying "that is not a DDS, it's a PLD, is like saying "That is not an
amplifier, it is a transistor."

In the description of how the device works in the data sheet they say
there is a DDS inside the programmable synthesizer.   It seems
reasonable that several functions are implemented inside the PLD and
this seems to be supported by the data sheet.
