Note:
1. 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
2. Specified for load stated in the Oscillator Output section at +25°C
3. External AC-Coupling capacitor required. ≥ 1nF is recommended
4. Frequency shift ≤1ppm after reliability test conditions (see section 7.0)
