Oscillator Temperature/Frequency Characteristics
The following characteristic graphics depicts typical oscillator behavior. The data presented here is a statistical sum-
mary 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.
