† Data in “Typ” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance
only and are not tested.
Note 1:
To ensure these oscillator frequency tolerances, V
DD
and V
SS
must be capacitively decoupled as close to
the device as possible. 0.1
F and 0.01 F values in parallel are recommended.
