Connection (top view):
Pad 2 and Pad 4 are common and connected
to the metal cover. They are not connected to
the crystal.
Layout and application information
Trace lengths to the crystal should be kept as short as possible.
The crystal connections are sensitive to noise.
The package should be grounded for optimum performance, pad 2 and/or pad 4 connected to ground.
