Oscillators are essential components in most electronic circuits. When building an oscillator, one needs to choose an oscillator device based on the type of signal desired, its quality, its performance requirements, and its cost. One type of oscillator is the SIT8919AA-11-XXE-120.000000G. This oscillator is well-suited for many applications due to its robust design and wide range of features. This article will provide an overview of the application field and working principle of the SIT8919AA-11-XXE-120.000000G oscillator.

The SIT8919AA-11-XXE-120.000000G is an ultra-miniature, surface-mount oscillator that is capable of generating a wide range of frequencies. It has a frequency range of 10 Hz to 120 MHz and a high frequency stability of ±10 ppm from -20°C to +85°C. This makes it suitable for a variety of applications such as modems, satellite receivers, radio and TV receivers, mobile phones, automotive systems, two-way radios, and medical equipments.

The SIT8919AA-11-XXE-120.000000G is also capable of providing a programmable frequency output with an integrated frequency divider. This allows for a frequency select function to be used, which can be used to adjust the output frequency within a wide range without changing the reference frequency. The total divider stages available are 8, 16, 32, and 64. Furthermore, the device\'s low power consumption of 4.5 mA at 3.3V makes it a good fit for battery-powered applications.

The SIT8919AA-11-XXE-120.000000G operates on the principle of Phase-Locked Loop (PLL) technique. It consists of an analog phase detector, low-pass filter, voltage-controlled oscillator, and a refrence oscillator. The analog phase detector compares the phases of the two oscillators and produces an error signal on one of its outputs. The error signal is then filtered by a low-pass filter to remove any unwanted noise. This is then fed into a voltage-controlled oscillator, which adjusts its output frequency to match the reference oscillator. The output of this oscillator is then used as the output frequency of the overall oscillator.

In summary, the SIT8919AA-11-XXE-120.000000G is an advanced oscillator with a wide range of frequency range and high frequency stability. Its small size, low power consumption, and integrated frequency divider make it a great choice for a variety of applications. Furthermore, its operation relies on the PLL technique, which allows it to generate a stable output signal with little error.
