So I am working on a board which have an IC from manufacturer Murata SCHA63T
The datasheet is a little bit vague about the recommended PCB design, but they offer a small evaluation board which I have studied: Eval Board
So there, they poured the entire top layer for GND. I would omit this and use an inner GND layer in my 4 layer design. I would ground the pins with close vias.
Would it cause problem? Or should I follow the eval board design?
