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.
