We have a design with 4 different Power and 2 Grounds.
We plan to put all 4 Power and AGND in one plan - layer 2 (close to DGND
plan - layer 3).
Hi-Speed Signals ( Rise time of 150 ps) are routed in other layers as strip
We would like to know:
Is there any limitation/ recommendations to the gap between the power
Do you recommend any "filter" between power areas?
Do you recommend any "filter" between power areas and AGND?
What should be the minimum thickness between the Power plane and layer1?
What should be the minimum thickness between the Power plane and layer 3?
