Programmable oscillators are electromechanical components used for frequency control. They are usually used in home appliances and industrial and military equipment to permit frequency setting within a given operating range. Generally, they have a wide range of applications in a variety of electronic circuits and systems. In this article, we will discuss the field of application and working principle of SIT1602BIF3-25S, a type of programmable oscillator.

Field of Application

The SIT1602BIF3-25S programmable oscillator is suitable for frequency control of communication systems, portable electronic devices and power supplies, positioning and navigation systems, automotive electronics, medical devices and industrial controllers. It is ideal for use in systems that require highly accurate and stable frequency control.

The SIT1602BIF3-25S is a low-cost, general-purpose oscillator optimized for operation in the 10 kHz to 25 MHz frequency range. It has a high frequency stability of ±1 ppm (under ideal) and is capable of generating accurate square-wave or sine-wave output signals. Its low power consumption and fast locking time make it ideal for embedded systems that require frequent frequency adjustment.

Working Principle

The SIT1602BIF3-25S uses a phase-locked loop (PLL) mechanism to generate accurate, stable output frequencies. The PLL contains a voltage-controlled oscillator (VCO) which is responsible for generating the output frequency. The VCO is then connected to a controlled oscillator (CO) which is used for setting the frequency. By controlling the voltage applied to the VCO, the output frequency is adjusted accordingly.

In addition, the SIT1602BIF3-25S also features a digital divider circuit. This circuit divides the CO frequency output by a programmable divisor to generate the desired output frequency. This enables the user to precisely adjust the frequency of the output signal.

The SIT1602BIF3-25S is further equipped with protection circuits to ensure that the output signals remain within their specified parameters. This includes over-temperature protection, over-voltage protection, under-voltage protection, power-down protection and over-load protection.

Conclusion

The SIT1602BIF3-25S is a reliable and cost-effective programmable oscillator offering a high frequency stability and wide application field. It is designed for use in a variety of systems such as automotive electronics, positioning and navigation systems, communication systems, and medical devices. The SIT1602BIF3-25S is equipped with a digital divider and PLL circuit to enable accurate and stable frequency control. Furthermore, it features protective circuits that help protect its output signals from over-temperature and over/under-voltage conditions.
