* 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: To ensure these oscillator frequency tolerances, V_DD and V_SS must be capacitively decoupled as close to the device as possible. 0.1 μF and 0.01 μF values in parallel are recommended. See the figure below.
