Programmable oscillators are commonly used for many applications where the frequency range and stability requirements are higher than what is available from regular crystal, RC, or LC oscillators. This is especially true in cases where the application requires narrow-band frequency, low-jitter, or low levels of phase noise. The SIT9121AC-2C-33S is a great example of a programmable oscillator that can meet such industrial requirements. To get a better understanding of this oscillator and its application field, let’s explore its working principle in more detail.

The SIT9121AC-2C-33S oscillator is a small, three-output Crystal Oscillator (XO). It has two output voltages and a host can select from multiple frequency sources. It can be divided into three operation modules, such as a channel selector, XO controller, and a frequency stabilization module. The XO controller produces a reference frequency based on the crystal frequency of the oscillator. This reference frequency is used to drive the frequency stabilization module which in turn output a stable output frequency. In addition, the XO controller can be used to program the frequency of the output through a series of commands from a control interface.

The SIT9121AC-2C-33S oscillator offers a wide range of frequency outputs, ranging from 1 to 100MHz. This means that it can be used in a variety of applications such as microprocessors, DACs, high speed networking, telecoms, and embedded systems. The oscillator also has a low inrush current and considerably low phase noise. It also has a low phase shift and jitter, making it ideal for applications where stability is important. In addition, the oscillator is available in a few different packages, making it easier to customize to meet specific needs.

The SIT9121AC-2C-33S oscillator is ideal for many applications where high performance and low noise is desired. It is also well suited for use in precision instrumentation, test and measurement systems, microprocessor applications and in embedded systems. The SIT9121AC-2C-33S oscillator is also used in high performance computing and in data communication systems. It is also used in automotive and industrial applications, where the need for frequency stability and low noise are paramount.

In terms of its working principle, the SIT9121AC-2C-33S oscillator produce a stable frequency signal. Its frequency stability comes from the crystal oscillator and from the frequency stabilization module. This frequency stability is then transferred to the output of the oscillator. The channel selector controls the frequency of the output and the XO controller controls the output voltage. By programming the XO controller, the frequency of the output can be accurately controlled.

In conclusion, the SIT9121AC-2C-33S oscillator is a great performer with a wide range of output frequencies, excellent noise and phase shift performance and an easy integration into existing systems. It is well suited for a variety of applications, such as high speed networking, telecoms, microprocessors, embedded systems, precision instrumentation and data communication. With its low inrush current, low phase noise and low jitter, the SIT9121AC-2C-33S oscillator can be used in a variety of environments to meet the high performance and low noise requirements of many applications.
