Oscillators

Oscillators are electronic circuits that generate a periodic signal without any outside excitation. They are used to generate a reference signal for electronic circuits and in communications devices to generate various frequencies and waveforms, such as for radio demodulation and for accurate time keeping. The SIT1602BI-11-25N-25.000000E oscillator is a typical example.

Application Field

The SIT1602BI-11-25N-25.000000E oscillator is mainly applied in communications and other electronic systems where precise timing and frequency is required. It utilizes a voltage-controlled crystal oscillator (VCXO) technology to maintain precise timing and frequency even when exposed to temperature changes, supply voltage changes, and vibration. It is also suitable for use in applications that require stable output in low power conditions. The device operates from a single 3.3V supply and supports frequency adjustments of up to 10 ppm.

Working Principle

The SIT1602BI-11-25N-25.000000E oscillator utilizes a voltage-controlled crystal oscillator (VCXO) design to achieve stable frequency generation. It utilizes a quartz crystal in series with a resistor and capacitor that is connected to an input voltage. When an input voltage is applied to the oscillator, the crystal begins to vibrate and generate a frequency proportional to the applied input voltage. This frequency is then amplified by an onboard amplifier and sent to the output of the oscillator. The frequency can be adjusted in small increments by changing the applied voltage. This allows for frequency accuracy even in the presence of temperature changes, supply voltage changes, and vibration.

Conclusion

The SIT1602BI-11-25N-25.000000E oscillator is a reliable and precise device for generating an accurate frequency reference signal in low power applications. It utilizes a voltage-controlled crystal oscillator design to provide fast and precise frequency tracking for applications that require stable output in a wide range of operating conditions.
