* These parameters are characterized but not tested.
** These parameters are design targets and are not tested. No characterization data available at this time.
† Data in the Typical (“Typ”) column is based on characterization results at 25°C. This data is for design guid-
ance only and is not tested.
Note 1: Measurements are taken in RC Mode where CLKOUT output is 4 x TOSC.
2: Please refer to Figure 13.1 for load conditions.
