The above Specification reflects the typical performance of this family of Oscillators.
Center Frequency, Temperature Stability, Aging, Phase Noise and Frequency Adjustment range are inter-related parameters. There are design
trade offs among this critical parameters and is not always possible to optimize all. Raltron Engineering can optimize to a specific requirement.
Please consult factory for your application.
