Notes:
1. For specifications other than those listed, please contact sales.
2. Not all combinations of VDD, Operating Temperature Range, Frequency Stabilty and Output Frequency are available.
3. Frequency Stability vs. Temperature is reference to the mid-point between minimum and maximum frequency values over the specified Operating Temperature
Range
4. Frequency Stability vs. Voltage and vs. Load changes are reference to the Nominal Frequency at 25°C
