Programmable Oscillators

Programmable oscillators are a type of oscillator that is used when an adjustable and stable oscillating signal is required that can easily be changed as needed. The SIT3808AI-D2-XXXX-000.FP0000X programmable oscillator is designed to do precisely this. It is a digital-controlled unit that is used in a wide range of applications, and this article will discuss what these applications are and the principle by which they work.

Applications

The SIT3808AI-D2-XXXX-000.FP0000X programmable oscillator is used in applications where a frequency-adjustable analog signal is required. It is most commonly used in telecommunications devices, such as telephone systems, to create a frequency-controlled tone that is used to signal an incoming call. It can also be used in transistor radio receivers to provide a frequency-tunable local oscillator signal.

This programmable oscillator is also used in some computer keyboards where press sensitive keys are required. It is used to energize a solenoid to create a "click" when a key is pressed. Other applications where this unit can be used include alarm systems, motion detectors, and cameras.

Principle of Operation

The SIT3808AI-D2-XXXX-000.FP0000X programmable oscillator is composed of a amplifier, a capacitive divider, an oscillaic generator, and a digitally controlled frequency divider. The outputs of the amplifier and the frequency divider is connected to the control input of the oscillator, and the output of the oscillator is a frequency-adjusted analog signal.

The programmable oscillator is programmed by connecting it to a computer via a serial bus. The computer sends commands to the oscillator, which allows it to be programmed to generate any frequency between 1 Hz and 200 MHz. The frequency can be adjusted in increments as small as 1 Hz.

Once programmed, the programmable oscillator can be used to produce a stable, frequency-controlled analog signal. The frequency can be adjusted to any value between the programmed limits without any further intervention from the computer.

Conclusion

The SIT3808AI-D2-XXXX-000.FP0000X programmable oscillator is a valuable tool for applications requiring an adjustable, frequency-controlled analog signal. It can be used in a wide range of applications, including telecommunications, computers, alarms, and motion detectors. By using a digital computer to program the oscillator, it can be adjusted to any frequency between 1 Hz and 200 MHz in increments as small as 1 Hz.
