24 layer stackup
Hi All
In my design I have 7 power supplies (1.2, 1.5, 1.8, 2.5, 3.3, 5, -5). I am using the following layer stack up.
top
gnd
power 1 (split plane for 1.5, 5)
signal 1
signal 2
power 2 (3.3 V)
power 3 (split plane for 2.5,-5)
signal 3
signal 4
power 4 (split plane for 1.8, 1.2)
gnd
bottom
Most of the signals with frequency 500 MHz pass through these split planes. will there be a lot of interference, or any other problem with this type of routing?
Having a separate layer for each power supply will increase the number of layers and cost, (that's why I went for split planes).
Is there a way I can reduce this interference and reflection.
Any help will be greatly appreciated
Thanks
