I have some doubt, If anybody know the reason/solution please let me know.
In my design I have used ADV7441ABSTZ-170, video IC for VGA and DVI inputs.
I have given 1.8V common source supply for PVDD, AVDD and CVDD supply pins of the IC as per datasheet.
I have just powered on the IC and no input or no configuration things are set yet.
Now, when I probe across the capacitors(other end are connected to ground) related to these I found below readings:
Supply - 1.803V
PVDD - 1.801V
CVDD - 1.800V
AVDD - 1.756V
Now, my question is,
Is there any particular reason for this small drop in voltage at AVDD pins of the IC ??
(Note that, I have used ferrite beads for separation of each voltages from 1.8V and other 3.3V voltages are good)
Please let me know ASAP.
Thanks in advance,
