1. CLKO loading is 50 pF max.
2. CLKO skew from the rising and falling edges of EXTAL will not differ from each other more than 1 ns, if the EXTAL rise time

The limits and values given in this section apply over the full case temperature range -
55°C to +125°C or -40°C to +85°C depending on selection see “Ordering Information”
on page Reference 2 and VCC in the range 4.5V to 5.5V V
The INTERVAL numbers (NUM) refer to the timing diagrams. See Figure 6 to Figure 25.
The AC specifications presented consist of output delays, input setup and hold times,
and signal skew times. All signals are specified relative to an appropriate edge of the
clock (CLKO pin) and possibly to one or more other signals.
