Question about powering ADRV9009

hi everyone,

 i'm trying to design a Schematic with ADRV9009,and i want make sure the difference about the ADRV9009 powering with DC-DC and LDO,the User Guide suggest  “Care must be taken toisolate the VDDA1P3_RF_SYNTH, VDDA1P3_CLOCK_SYNTH, and VDDA1P3_RF_LO pins from the VDDA_1P3_ANALOG supply. This isolation is critical to achieving best phase synchronization performance” ,so, where can i find the details about the current of each branch such as  VDDA1P3_RF_SYNTH, VDDA1P3_CLOCK_SYNTH, and VDDA1P3_RF_LO pins。

 THANKS !
