If you are using integer mode (LTC6945), the LTC6946 would be the lower cost option with integrated VCO. LTC6948 can be an integer or fractional part.
In my design I am evaluating the possibility to involve an AD9958 as DDS.
The output of the DDS is in the range 90 - 180 MHz. Each output is transformed in single-ended by means of a Balun (TCM4-6T), and than filtered with a Band Pass…
Got no ans in DDS section, I try again posting here.
Sorry for doubling.

Here's an app-note (attached) that expands on the FAQ above.
One other thought is the LTC6954. It has 6 outputs pins (3 differential, or 6 CMOS, or some combination CMOS/differential). It is in the same family as the LTC6957, but with more outputs and its programmable. If you were thinking of using CMOS…
The short answer is:
LTC6945, LTC6946: PLLWizard
LTC6948: Either FracNWizard or ADIsimPLL
ADIsimPLL (https://form.analog.com/Form_Pages/RFComms/ADISimPll.aspx )
What loop filter design tool should I use for LTC694x PLLs and PLL/VCOs?
