In this article, we will discuss the application field and working principle of SIT9120AC-2B1-25E133.333333D.

The SIT9120AC-2B1-25E133.333333D oscillator is commonly used in applications such as frequency synthesisers, precision clocks, frequency counters, and clock generators. Its stability ensures that the desired output frequencies remain constant and reliable. It also offers fast settling time and high reliability and accuracy. This enables users to achieve the best possible results when using the oscillator.

The SIT9120AC-2B1-25E133.333333D oscillator has two main components: the Crystal Unit (CU) and the Control Unit (CU). The CU is an integrated crystal oscillator assembly that provides precise frequency stabilization and low frequencies at different voltages. The CU is designed to meet the tightest timing requirements and offers the best performance for applications that require the highest level of accuracy. The CU comprises a quartz crystal and associated components that are assembled together to form the oscillator circuit.

The CU uses the quartz crystal to establish the fundamental frequency for the oscillator. The crystal is connected to a capacitive circuit provided with a frequency-determining device. By adjusting the capacitive network, the oscillation frequency can be controlled and the signal frequency stabilized. This is accomplished by providing an external voltage or current to the circuit, which is used to control the frequency of the oscillator.

In most applications, the CU also provides various functions such as low-phase noise emission, wideband frequency synthesis, pulse generation, frequency measurement, and temperature stabilization. This makes the device ideal for a variety of timing applications, including power management, digital frequency control, frequency synthesis, and automatic testing.

The SIT9120AC-2B1-25E133.333333D oscillator uses a PLL (Phase-Locked Loop) circuit for the frequency stabilization. This circuit consists of a reference oscillator, a prescaler, a loop filter, a voltage-controlled oscillator (VCO), and a comparator. The reference oscillator generates a signal which is used as the reference frequency to compare with the output of the VCO. The comparator then adjusts the VCO to lock the output frequency to the reference.

The PLL also provides a high degree of accuracy and stability. The loop has low phase noise emission, as well as excellent temperature stability and frequency stability. It can also provide an extremely wide range of operating frequencies, making it suitable for a variety of applications. Another advantage of this technology is that it is able to provide a wide range of output frequencies, allowing the user to synchronize the device with different components of a system.

In conclusion, the SIT9120AC-2B1-25E133.333333D oscillator is a high-performance, high-precision, and highly reliable oscillator that is suitable for use in a variety of timing applications. Its application field includes frequency synthesis, power management, digital frequency control, frequency synthesis, and automatic test. Its working principle is based on a PLL circuit, which provides a high degree of accuracy and stability. This makes the SIT9120AC-2B1-25E133.333333D oscillator an ideal choice for many timing applications.
