9.2.2.5 Unused Inputs and Outputs

If VCXO pulling functionality is not required, Vctrl must be left floating. All other unused inputs must be set to GND. Unused outputs must be left floating.

If one output block is not used, TI recommends disabling the output block. However, TI always recommends providing the supply for the second output block even if the output block is disabled.
