Hello All,
In my current board design I have the following stack up:
.......
---------------- GND (solid plane)
------ ----- --- VCC1 (splitted plane)
--- ----- ------ VCC2 (splitted plane)
---------------- GND (solid plane)
.......
4 mils separate GND and VCC planes
5 mils separate VCC1 and VCC2 planes
Both VCC planes are splitted in different power domains and I am wondering
:
- if having two coupled VCC planes is good/acceptable when
thinking about noise ??
- if there is a problem in having one power domain on on plane
overlapping at least two power domains on the other plane ??
Thanks
Ludovic Levieil
