In my design I am using a quartz crystal of 22.1184MHz. The design is supposed to restrict electro-magnetic emissions at a lowest possible level. What are the necessary guidelines that I need to follow while routing so that emissions due to Crystal can be substantially reduced. Would grounding the body of Crystal suffice or I need to include separate Power and Ground Planes in my design to minimize the 3rd, 5th and 7th harmonics generated due to this crystal ?.
