A maximum frequency stability over the temperature is required to be specified. Standard options are ±0.5ppm,
±1.0ppm, ±1.5ppm, and ±2.5ppm.
Parts should be shielded from drafts causing unexpected thermal gradients. Temperature changes due to ambient
air currents on the oscillator can lead to short term frequency drift.
The operating temperature range needs to be specified. The extremes for this model are -40 and +85° C.
The maximum value is the specification. A minimum value, if present indicates the best specification available.
The unit will operate on any voltage between minimum and maximum values.
Specified for load stated in the Oscillator Output section at +25° C.
External AC-Coupling capacitor required. ≥ 1nF is recommended.
The recommended load resistance is ≥ 100kΩ. The load capacitance must be minimized for optional
performance.
REFERENCE DESIGN INFORMATION:
ASTXR-12-26.000MHZ-512545 is equivalent to Rakon P/N 512545.
