Hi All,
I have a basic doubt while routing my board. Following is the layer stackup
what I am using.
1 ________________Signal
2 ________________Gnd.
3 ________________Signal
4 ________________Signal
5
________________Pwr.
6 ________________Gnd.
7 ________________Signal
8 ________________Signal
9 _______________ Pwr.
10________________Signal
My question is I am trying to maintain the same reference plane for routing
track, For example I am starting a clock trace from top layer then switching
to Signal layer 3 (GND ref) and then to Signal layer 7 ( GND ref). I am
assuming this should be ok since it is having same GND as reference for the
entire track. Is it advisable to have such practice to cross the layer
pairs ? If I have a continuous plane Layer 5 (PWR) can I switch between
signal layer 3 (GND ref ) and Signal layer 5 ( PWR Ref) for the same track.
Any difference in these two type of switching in signal integrity
perspective. Kindly share your feedbacks.
Thank you,
Vijay
