2. This parameter is tested in standby mode.
3. These parameters are not 100% tested, but are calculated at initial characterization and at any time the design is modified where
frequency may be affected.
4. tCF is a calculated value and is not guaranteed. tCF can be found using the following equation:
tCF = 1/fMAX (internal feedback) – tS.
