capacitance may be affected.

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 modiï¬ed where
frequency may be affected.
4. Output delay minimums for tPD, tCO, tPZX, tPXZ, tEA, and tER are deï¬ned under best case conditions. Future process improvements
may alter these values therefore, minimum values are recommended for simulation purposes only.
5. tCF is a calculated value and is not guaranteed. tCF can be found using the following equation:
tCF = 1/fMAX (internal feedback) â tS.
