Oscillators

An oscillator is an electronic device that is designed to generate an alternating electrical current or voltage. They are used extensively in electronics applications, such as in circuits that require frequency stabilization, timing and control, and signal modulation. A common type of oscillator is the quartz crystal oscillator, which uses a piezoelectric crystal to generate a signal with a precise frequency. The SIT8918BE-13-33N-25.000000G oscillator is a miniature voltage-controlled crystal oscillator (VCXO) designed for use in applications requiring precise frequency control.

Applications

The SIT8918BE-13-33N-25.000000G oscillator has a wide range of applications, including cellular base station systems, WiMax systems, GPS receivers, and automotive communications systems. It can also be used in avionics systems, satellite systems, and measurement and test equipment. The VCXO is designed to provide precise control of frequency with a very small frequency error (typically 0.5 ppm or less). It is also capable of providing very low phase jitter, allowing it to be used in systems that require highly precise, stable, and reliable frequency control.

Working Principle

The SIT8918BE-13-33N-25.000000G oscillator employs a quartz crystal resonator, which is a piezoelectric device that will vibrate at a specific frequency when voltage is applied. The frequency of the crystal resonator is then modified using an external (or internal) voltage control mechanism, allowing precise frequency control. The voltage control mechanism works by modifying the voltage across the quartz crystal, which in turn adjusts the frequency of the oscillator. This allows for very precise frequency control, with small frequency errors.

The SIT8918BE-13-33N-25.000000G oscillator is able to provide low jitter performance, which is important for applications that require precise synchronization. Jitter is a measure of the amount of timing variation in the output signal, typically expressed as a jitter frequency. The lower the jitter frequency, the more stable and reliable the frequency control will be.

The SIT8918BE-13-33N-25.000000G oscillator is a reliable and accurate frequency control component that is suitable for use in a wide range of applications. Its small size and low power consumption also make it ideal for use in portable or battery powered devices, such as cell phones or tablets.
