* Frequency setting conditions : Frequencies are set at normal temperatures(+25±2°C).
                                                   Connect the #1 terminal of the oscillator to the ground that comes with the oscillator.
*1. A DC-cut capacitor is not embedded in this crystal oscillator. Connect a DC-cut capacitor (1,000 pF) to the line-out terminal of the oscillator.
