Oscillators

Oscillators, also known as timing-devices, are electronic circuits used to create repetitive waveforms. They are used in a wide range of applications including clocks, modems, power amplifiers, satellite communications systems, avionics, and others. The SIT1602BC-22-25E-4.000000E is a specific oscillator designed to provide a highly precise and stable clock signal.

Application Field

The SIT1602BC-22-25E-4.000000E oscillator is designed for applications requiring a low power, highly stable clock signal. It is suitable for powering precision timing circuits in applications where guaranteed accuracy and reliability is essential, such as clocks, calendar alarms, avionics, computer motherboards, and others. The clock is also suitable for powering logic circuits, such as analog-to-digital converters and digital-to-analog converters.

Working Principle

The SIT1602BC-22-25E-4.000000E oscillator is based on a quartz oscillator circuit. Using the quartz crystal as an element for electrical vibration, the oscillator produces a highly stable clock signal. The frequency is determined by the oscillation frequency of the quartz crystal, set to the desired value at the time of manufacture. The frequency of the output signal is determined by the values of an external capacitor and the integrated oscillator circuit. The clock signal is kept stable through the use of a temperature compensation circuit integrated inside the oscillator. This circuit is composed of an integrated temperature detection circuit and a temperature compensation circuit. This allows for the correction of frequency variations due to temperature changes. The temperature detection circuit is connected to a temperature compensation capacitor which is divided into two parts connected in parallel. The two halves of the capacitor are kept at different temperatures in order to adjust the clock frequency. The SIT1602BC-22-25E-4.000000E oscillator also features a low power consumption and low phase noise. The low power consumption allows the crystal oscillator to be used in batteries powered applications, while the low phase noise ensures that the generated signal is free from jitter and deviation.

Conclusion

The SIT1602BC-22-25E-4.000000E oscillator is a highly stable and accurate clock generator designed for applications requiring precise timing circuitry. It features a quartz crystal oscillator circuit with a temperature compensation circuit, allowing it to maintain highly accurate clock frequencies in all environmental conditions. The low power consumption and low phase noise make it suitable for a wide range of applications from clocks and alarm signals to logic circuit timing sources.
