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 connected to ground.
These very sm all crystals have high ESR, the oscillator start-up and operation should take this into
consideration.
• These sm all crystals should have their m axim um drive level lim ited to 100uW .
