Oscillators - SIT1602BI-81-18E-30.000000Y

Oscillators are active electronic components that generate a sinusoidal AC signal. This signal can serve many purposes, such as generation of a clock signal for synchronizing digital circuits, or can be used as frequency reference signals for radios. In this article, we look at the application field and working principle of the SIT1602BI-81-18E-30.000000Y oscillator.

Application field:

SIT1602BI-81-18E-30.000000Y Oscillators are primarily used for frequency stabilization and clock synchronization. It is used for low phase noise, stability, and wide range of applications including test & measurement, computer clocks, instrumentation, telecommunications, broadcast & entertainment, and military & aerospace.

Working Principle:

SIT1602BI-81-18E-30.000000Y uses the modern design approach of integrating high performance, low phase noise oscillator and control circuits. This sophisticated arrangement of components provides almost instant tuning and high stability while outperforming traditional oscillators on both metrics. The SIT1602BI-81-18E-30.000000Y is a low-phase-noise, voltage controlled crystal oscillator (VXCO) in which a varactor diode and a crystal are the main components. The internal control circuitry tunes the varactor diode actuation voltage to provide precise adjustments of the set frequency. A negative resistance circuit in conjunction with a voltage controlled amplifier acts as a frequency stabilizer, creating a feedback loop to fine-tune the frequency of the crystal. The quartz crystal acts as a resonator, undergoing mechanical resonance when its motional impedance is matched to the load impedance. This resonance condition occurs at a specific frequency, determined by the mass and charge of the crystal you use.

Conclusion:

The SIT1602BI-81-18E-30.000000Y oscillator can be used in many applications requiring frequency stabilization and clock synchronization. It offers superiority over traditional oscillators with its low phase noise, stability, and wide range of applications. Its ability to achieve precise adjustments of set frequencies and fine-tuning of the crystal frequency through the internal control circuitry makes it an ideal choice for many use cases.
