41110 Customer Reference Boards 11
This chapter describes the 41110 Customer Reference Board (CRB).
11.1Board Stack-up
The proposed layout of the PCB is eight layers with the following stackup:
•Signal #1 (Top/Component Side)
•Ground Plane: GND
•Signal #2
•Power Plane
•Power Plane
•Signal #3
•Ground Plane
•Signal #4 (Bottom)
The permittivity constant Er = 4.5
