Hello,

 

DVDD12 (#35 and #36) is supplied by DVDD12 in AD9152-FMC-EBZ RevA Schematic, while #35 and #36 is supplied by DVDD12 and MUSH_VDD respectively in AD9152-EBZ RevB Schematic and AD9152-ADRF6720-EBZ RevB Schematic. Why #35 and #36 is supply by different PMIC? Is separating power supply necessary?

 

Best Regards,
