Oscillators are used to generate a continuous periodic signal to control the timing interval in electronic circuits by using an electronic oscillator configured with an RC circuit or LC circuit to provide alternating current through self-resonance. Among them, SIT1602BC-72-25E-28.636300D is a high-performance product of Sitronix Technology Corporation. The product is widely used in electronic and electric products such as TVs, navigation systems, automotive electronics, medical and fitness equipment, and remote controls. The following is a detailed introduction to the application field and working principle of SIT1602BC-72-25E-28.636300D.

The application field of this crystal oscillator is mainly related to the frequency range and stability. Specifically, it covers an extremely wide frequency range from 8kHz to 170MHz and offers an excellent frequency stability of ±100ppm and temperature stability of ±7.9ppm. With such excellent performance, it can be used as a system timing generator for a variety of audio and video applications.

SIT1602BC-72-25E-28.636300D is designed with a fundamental oscillator core and an external oscillator circuit. The frequency determines loop structure is designed with an external quartz resonator, this resonator is the main component of the oscillator, the oscillation frequency generated by the quartz crystal is determined by the structure parameters, such as the capacitance that loaded to the quartz resonator, and the resistance of the feedback circuit. The resonance frequency of the quartz crystal oscillator can be obtained by the following formula: F=1/(2π√LC), where L is the inductance of the quartz resonator and C is the capacitance of the quartz resonator.

The output of the oscillator is designed to be an open drain buffer, which mainly outputs low-frequency signals below 10MHz. The circuit also includes a frequency divider to generate a variety of output frequencies. The frequency division can be divided into two types: internal division and external division. The internal frequency divider includes a programmable circuit that allows the user to select the frequency. If an external frequency divider is used, an external resistor and capacitor can be used to tune the frequency.

In order to make the oscillator temperature stable, the oscillator has a built-in temperature compensated circuit. The operation of this circuit is to monitor the temperature changes in the oscillator, adjust the oscillation frequency, and output the temperature compensated frequency signal. This feature makes the oscillator temperature stable and reduces the influence of temperature changes on the oscillation frequency of the oscillator.

SIT1602BC-72-25E-28.636300D combines the functions of frequency synthesis, timing, frequency divider, etc., and has a stable oscillation frequency, low power consumption, small size, and a wide range of operating temperatures from -20℃ to 85℃. It is suitable for all kinds of portable electronic products, such as navigation systems, remote controls, industrial and medical devices, etc. This crystal oscillator is widely used in electronic and electric products and is an ideal choice for product design.
