• Frequency setting conditions
1. Frequencies are set at normal temperatures (+25±2°C).
2. Frequencies are set with a printed board that has a
ground pattern attached to the underside of an oscillator.
• If you require a product with a different frequency, power
supply voltage, frequency control characteristic, etc. to the
standard specifications, please contact us with your
enquiries.
• Products with the AFC (Automatic Frequency Control)
function are available. If you require such a product, please
contact us.
*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.
*2. This is a representative specification. The specifications
may change according to the frequency that you request.
