Having a 32-bit DAC would give you enough range so that you could drop in any OCXO you might have. But if you can have trimmer resisters to selected for your specif OCXO then 16-bits should be enough. If it were me, I'd want the DAC steps to be smaller than what the phase detector can measure. Said another way a 32-bit DAC might eliminate the need for scale and offset trimmer resistors.
