Notes:
1.
The period specified here is the average period. A given period may vary from this specification as governed by the
period Stability specification (T2).
2.
In this context, period stability is defined as the worst case timing difference between successive crossover voltages. In
other words, the largest absolute difference between adjacent clock periods must be less than the period stability.
3.
Slew rate is measured between the 35% and 65% points of the clock swing (VL to VH).
4.
Combining the longest clock-high and clock-low times would violate the max clock period, and that combining the
shortest clock-high and clock-low times would violate the minimum clock period. The clock-high and clock-low times
specify the most extreme allowable combination of clock period and duty cycle.
5.
Slew rate specifications apply to both rising and falling edges.
6.
Guaranteed by design. These values are typical values seen for this process, but not measured during production
testing.
