Hello,

 

I have a question about VDD_IO and VAA of ADV7392.

Question:
  Are VDD_IO and VAA connected internally in ADV7392?
  The customer is going to prepare two LDO's for VDD_IO and VAA (these are powering-up within 1s).
  He worries about power current flows backwards to another supply during powering-up/down.
  (If VDD_IO and VAA are connected internally in ADV7392, we think power current flows backwards to another supply.)
  So we hope VDD_IO and VAA are not connected internally.

 

Thank you.

Best regards.
