Oscillator Temperature/Frequency Characteristics

The following characteristic graphics depicts typical oscillator behavior. The data presented here is a
statistical summary of data gathered on units from different lots over a period of time. This is for
information only and the figures were not tested during manufacturing.

In some of the graphs, the data exceeding the specified operating range are shown for information
purposes only. The device will operate properly only within the specified range.
