Oscillators are devices that produce periodic waves in electronic circuits, by means of creating and maintaining a specific signal frequency. The SIT1602BC-21-18N-66.666660E oscillator is an example of such a device used in electronics.

The SIT1602BC-21-18N-66.666660E oscillator is a hermetically sealed quartz crystal micro circuit with a frequency stability of 0.1ppm/°C. It typically has a frequency range of 72.576MHz - 8KHz, with a frequency adjustment range of ±5,000ppm. It has a built-in full bridge oscillator with external bias and have porcelain packaging or other molded plastic package. It is also available in a low power version that is easier to integrate onto a PCB.

The main application field of SIT1602BC-21-18N-66.666660E oscillator is in radio frequency and control circuitry. It is used in many applications such as radio receivers, digital computers, clock circuits, frequency synthesizers and modulators, and diffractometers. Because of its high stability, low power consumption and small size, this type of oscillator is also known as a low-jitter application-specific integrated circuit (ASIC). Oscillators are also used in the construction of radio communication systems, to create constant signal reference.

The working principle of the SIT1602BC-21-18N-66.666660E oscillator is based on the use of a quartz crystal. A quartz crystal is a quartz stone exhibiting piezoelectricity, a property by which electricity is converted into mechanical vibration and vice versa. Quartz crystals have an ability to oscillate at a constant frequency, which can be accurately controlled. The quartz crystal is set in a oscillator circuit and is connected to the output amplifier that amplifies the generated waveform and transfers it through a leaded or plastic package.

This oscillator circuit contains a capacitor, an inductor and resistors, which form the LC circuit, known as the quartz crystal resonator. By passing an alternating current through the LC circuit, the oscillator absorbs energy. This energy is then stored in the capacitor, which is discharged during the trough of the oscillation. It then recharges, inducing the same frequency of the wave of vibration, which is the oscillator frequency. The oscillator frequency can be controlled by adjusting the capacitance of the resonator or the current of the amplifier.

The SIT1602BC-21-18N-66.666660E oscillator is commonly used in many applications, due to its small size and high frequency stability. Its typical applications involve controlling the timing of various data systems and data transmissions and working with radiofrequency equipment. Furthermore, it can also be used as a reference frequency for radar and communication applications.
