* All aging stabilities are after storage of up to 1 year and apply after 30 days of continuous operation.
The daily aging rate also applies at the time of shipment from factory.
* The Electrical Frequency Adjustment Range is sufficient for the life of the oscillator.
Specification subject to change with Frequency.
Available Frequency Range:
5MHz to 40MHz including 5.0, 10.0, 16.384, 19.44, 24.576 and 32.768 MHz.
