capacitance may be affected.

2. Output delay minimums for tPD, tCO, tPZX, tPXZ, tEA, and tER are defined under best case conditions. Future process improvements
may alter these values; therefore, minimum values are recommended for simulation purposes only.
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.
