These parameters are characterized but not tested.
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.
