* These parameters are characterized but not tested.

† Data in the Typical (“Typ”) column is at 5V, 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.
