Connection (top view):
Pad 2 and Pad 4 are common and connected
to the metal cover. They are not connected to
the crystal. Connected to ground is
recommended
The crystal is symmetrical, there is no Pad 1
preference. The part can be rotated 180
o
when
being assembled on the PCB and will still
perform correctly.
