The area underneath the module at the second layer,
and 3 cm in all directions around the module, is defined
as the critical ground plane zone. The ground plane
should be maximized in this zone. Refer to application
note AN1114 or the Lite-On IrDA Data Link Design Guide
for details. The layout below is based on a
2-layer PCB.
