Oscillators are an integral part of many electronic systems. They are commonly used to generate signals of specific frequencies and produce clock pulses to synchronize the operations of integrated circuits. This article will provide an overview of the SIT3907AC-CF-33NM-200.000000Y oscillator and its application fields and working principle.

Application Fields

The model SIT3907AC-CF-33NM-200.000000Y is a quartz based, fundamental mode, miniature surface-mount oscillator. It is designed with a frequency range of 38.4 – 52.1 MHz and a temperature stability of ±50 PPM. It is rated for a temperature range of -10°C to +60°C. Its small size make it suitable for applications with space restrictions and its frequency accuracy and stability make it suitable for general purpose and even standard timing and clock generation applications.

Working Principle

A quartz crystal provides the oscillation frequency for the SIT3907AC-CF-33NM-200.000000Y oscillator. A quartz crystal consists of a thin slice of quartz with metal electrodes deposited on each side and held under tension so that the crystal vibrates at a specific frequency when an electric field is applied. A piezoelectric effect is produced when voltage is applied to the electrodes, causing the crystal to vibrate. The frequency of the vibration is determined by the size and shape of the crystal.

The SIT3907AC-CF-33NM-200.000000Y oscillator is designed to drive a quartz crystal at a frequency of 38.4 – 52.1 MHz. The quartz crystal is connected to a two-stage Pierce oscillator circuit. This circuit comprises an amplifier with positive feedback, a resistor, and a capacitor. The output from the amplifier alternately charges and discharges the capacitor, and a pulse is produced whenever the capacitor voltage reaches the threshold level of the amplifier. This pulse causes the crystal to resonate, thus generating the oscillation frequency. The frequency of oscillation is determined by the quartz crystal and the components of the Pierce oscillator circuit.

Conclusion

The SIT3907AC-CF-33NM-200.000000Y oscillator is a quartz-driven oscillator used to generate a range of frequency between 38.4 – 52.1 MHz. It features a two-stage Pierce oscillator circuit and a quartz crystal to produce an oscillation frequency. The SIT3907AC-CF-33NM-200.000000Y oscillator is suitable for a variety of standard timing and clock generation applications due to its high accuracy and stability. It is also small in size, making it suitable for applications where space is limited.
