Oscillators are devices that can generate a periodic and stable wave signal output. In the field of communication and automation, they are widely used. SIT9003AC-84-33ED-18.43200T is an oscillator manufactured by a well-known company. It is definitely a great choice for wireless audio, music and other applications. The following will explain the application field and working principle of SIT9003AC-84-33ED-18.43200T.

Application Field

SIT9003AC-84-33ED-18.43200T is suitable for wireless audio, music and other applications. It has an ultra-low operating current of 3.6 mA, which is only one-third of the energy consumption of traditional oscillators. At the same time, it has a frequency stability of 0.1 ppm, providing customers with a reliable clock source. SIT9003AC-84-33ED-18.43200T is also a high-performance, low-noise oscillator with a noise level of only -135 dBc/Hz.

Working Principle

SIT9003AC-84-33ED-18.43200T uses a quartz crystal to control the frequency of its output signal and generates an output signal with a frequency within a very narrow range. This quartz crystal is mounted inside an oscillator circuit that includes an amplifier, an oscillator transistor, and a feedback loop. The oscillator transistor amplifies the signal from the quartz crystal and provides the periodic signal output. In order for the oscillator to achieve its designed frequency, there needs to be a feedback loop to provide a steady input so that the frequency of the signal to remain constant.

The entire oscillator circuit is powered by an external voltage source which is supplied externally. The feedback loop of the oscillator is made up of two components: a resistor and a capacitor. These components form a low pass filter, which allows only the signals that are below the crystal\'s resonance frequency to pass through and be amplified. The frequency of the feedback loop is set so that it is slightly higher than the frequency of the quartz crystal. So that when the quartz crystal vibrates at a certain frequency, the frequency of the output signal will always stay at the same frequency.

In summary, SIT9003AC-84-33ED-18.43200T is a low-energy, high-performance, and low-noise oscillator suitable for various wireless audio, music and other applications. Its working principle is based on a quartz crystal and an oscillator circuit composed of an amplifier, an oscillator transistor and a feedback loop. Low pass filter in the feedback loop allows the signals below the crystal\'s resonance frequency to be amplified and keep the output signal\'s frequency stable.
