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.
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 optim um perform ance, pad 2 and/or pad 4 connected to ground.
