I have a board that will take some 10 MHz clock lines and I was planning on surrounding said clock lines with ground traces to minimize interference with some other traces. I've been told to keep these ground traces about 30 mils from the signal line to reduce the capacitive load.
It is a 4 layer board, with two ground planes in the middle. My question is, should the ground trace connections also be connected to the ground plane? (This will happen through the same via where the connector is mounted to the PCB).
I'm aware that they are already technically shorted, since they are both sharing the same ground, but wanted to check if there was some reason why this is or is not a good idea (beginner at PCB design here).
