1. Parameters are given by selecting 10 MHz I/O output frequency.

2. Values based on design simulation and/or characterization results, and not tested in production.

3. Min time is for the minimum time to drive the output and the max time is for the maximum time to validate

the data.

4. Min time is for the minimum time to invalidate the output and the max time is for the maximum time to put

the data in Hi-Z.

5. Data characterization in progress.
