• Frequency setting conditions
1. Frequencies are set at normal temperatures
(+25±2 °C).
• If you require a product with a different frequency,
power supply voltage, frequency control range,
etc. to the standard specifications, please contact
us with your enquiries.
*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.
