Due to their outstanding performance, low cost, and easy installation and maintenance, these oscillators are commonly used in a range of applications.

The SIT9002AC-43H25DT series is especially suitable for use in automotive electronics, radio communication systems, radar systems, power supply frequency synchronization, etc. The following are some of the automotive electronics areas the oscillators find particular application:

• Engine control units (ECUs) for engine monitoring
• Braking systems
• Fuel injection systems
• Transmission control systems
• Airbag systems
• Ignition systems
• Vehicle emission control systems.

The oscillators can also be used in other areas due to their output frequency accuracy, stability and excellent low-power consumption.

Working Principle

The SIT9002AC-43H25DT series is constructed using a microcontroller that is pre-programmed with a single oscillation frequency. This frequency can be changed by supplying a different voltage to the oscillator. In a typical setup, a voltage is applied to the oscillator, which then generates a signal with a frequency that is adjustable over a wide range of frequencies. It is important to note that the oscillator does not produce an oscillating signal itself; it only generates a single frequency that is adjustable. This signal is then sent to other components in the system, such as amplifiers, filters, and other electronic components, to complete its function.

The SIT9002AC-43H25DT series also has variable amplitude control and variable duty cycle options. The variable amplitude control can be used to adjust the output signal level while the variable duty cycle can be used to provide a wider range of possible frequencies. Additionally, the oscillator can be programmed to start at a particular frequency, provide a pulse width adjustment feature, and generate a signal with a fixed waveform.

In summary, the SIT9002AC-43H25DT is a versatile, low-cost, and easy to use programmable oscillator designed for automotive electronics applications. It provides excellent accuracy and stability of output frequency, and its adjustable amplitude, duty cycle and waveform features make it a highly desirable choice for many applications. As such, it is used in a number of industries to meet requirements for sound, wireless, location-based, embedded, diagnostic, and automotive applications.
