* 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, V
DD 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.
