Programmable Oscillators are electronic devices that generate a repetitive waveform at a specific frequency. The SIT3809AI-C-28NY is a type of programmable oscillator that can be used for a variety of applications, from clock and oscillator circuits to frequency control and time delay applications. In this article, we will explore the application fields and working principles of the SIT3809AI-C-28NY.

The SIT3809AI-C-28NY is a versatile programmable oscillator that offers a wide range of features, including frequency range up to 80MHz, dual output clock sources, on/off control and adjustment of frequency, multi-frequency function, on-chip crystal oscillator, CLKA/CLKB selectable mode, power-down mode, and high stability and consistency. Due to its small size and low power consumption, the SIT3809AI-C-28NY is ideal for various applications, including high-speed digital systems, microcontrollers, digital signal processing, home appliances, and industrial electronics.

The SIT3809AI-C-28NY is a digitally controlled clock signal generator that uses a high-voltage resistor-capacitor (RC) oscillator circuit for frequency control. The RC oscillator can be programmed with a single resistor and a single capacitor to produce a frequency within a range of 50 Hz to 80 MHz, which is ideal for high-frequency application requirements. In addition, the user can select the “CLKA/CLKB selectable mode” for different types of frequency outputs. With this feature, the user can have a single oscillator with two-phase outputs, a tri-state output, or both at the same time.

The SIT3809AI-C-28NY has a dual output clock source feature, which allows two independent clocks to be generated. This is beneficial in applications that require two independent clocks to operate, such as digital video recorders (DVRs), multiplexers and modulators. In addition, the user can adjust the frequency of the clock output by applying a voltage input to the device. The SIT3809AI-C-28NY also has a power-down mode that enables the device to lower its power consumption when it is not in use. This feature makes the SIT3809AI-C-28NY perfect for applications where low power consumption is important, such as battery-operated devices, portable electronics and medical equipment.

The SIT3809AI-C-28NY is also capable of generating multiple frequencies for applications such as frequency hopping, frequency scanning, and phase-lock loop (PLL) applications. This is accomplished by using the on-chip crystal oscillator, which allows the user to program multiple frequencies with a single resistor and capacitor. With this feature, the user can generate custom frequencies, which can be used for various applications such as frequency control, time delay, and clock synchronization.

The SIT3809AI-C-28NY is also characterized by its high stability and consistency. The device’s characteristics are consistent over a wide range of temperatures, providing a long-term frequency stability for many applications. This makes the SIT3809AI-C-28NY an ideal choice for automotive, telecommunication and military applications.

In conclusion, the SIT3809AI-C-28NY is a versatile programmable oscillator that is well-suited for many different applications. With its wide range of features, such as dual output clock sources, on/off control and adjustment of frequency, multi-frequency function, on-chip crystal oscillator, CLKA/CLKB selectable mode, power-down mode, and high stability and consistency, the SIT3809AI-C-28NY is an excellent choice for applications that require a reliable and flexible oscillator.
