SIT9003AC-23-33SD-14.74560Y oscillator is widely used in a variety of professional audio and consumer audio applications, mainly as a timing source for digital signal processing and sound synthesis due to its high accuracy and stability. Its general application fields include tools for computer recording and audio restoration, musical instruments, multi-channel recording systems, parametric equalizers and so on. Moreover, this type of oscillator is also good for stable power supply for amplifiers, mixers, loudspeakers, home theater equipment and the like.

Working Principle

The working principle of the SIT9003AC-23-33SD-14.74560Y oscillator is based on a two-stage amplifier system combined with a variable quartz oscillator tuned to between 10 to 73 kilohertz. The first, or input stage, amplifies the low level signals input from the Quartz crystal so that they are of an amplitude sufficient to be used by the oscillator circuit. The second stage further amplifies and then passes these amplified signals to the Quartz crystal in a Feed Back Loop. The oscillator generates a frequency based upon the selected quartz crystal and is a combination of a power amplifier detailed with a variable frequency oscillator and a sensitive quartz crystal. The oscillator uses an automatic adjustment system to adjust the crystal frequency so that it is stable and accurately reproduces the frequency set. With this system, the oscillator can quickly and accurately detect the signal level output from the quartz crystal and use it to achieve optimal stability over long periods of time.In conclusion, the SIT9003AC-23-33SD-14.74560Y type of oscillator is accurate, reliable and easy to use, making it ideal for use in a variety of audio applications. Furthermore, its precision and stability can help achieve high-quality performance with minimal effort.
