1. Typical specifications are not guaranteed.

2. Duty cycle: min = 40% max = 60%

3. In case of mode change (from low-power to performance mode or vice versa), the clock has to be continuous or has to be

stopped for at least 50 μs.

4. Input clock in static mode

5. Time from the first clock edge to valid output data
