These parameters are characterized but not tested.
Data in ‘Typ’ column is at 5.0V, 25
°C unless otherwise stated. These parameters are for design guidance
only and are not tested.
Note 1:
To ensure these oscillator frequency tolerances, VDD and VSS must be capacitively decoupled as close to
the device as possible. 0.1 uF and 0.01 uF values in parallel are recommended.
