Connection (top view):
Pad 2 and Pad 4 are com m on and connected
to the m etal cover. They are not connected to
the crystal. Connected to ground is
recom m ended
The crystal is sym m etrical, there is no Pad 1
preference. The part can be rotated 180
o
when
being assem bled on the PCB and will still
perform correctly.
