Programmable Oscillators and Their Uses

Programmable oscillators are electrical circuits or components which produce repeating, periodic signals appropriate for a wide variety of applications. These circuits are often designed with a programmability to enable the user to set them to the relevant frequency. This article will cover the field where the SIT9005ACR2G-XXSD is typically used and its working principles.

Uses of the SIT9005ACR2G-XXSD Programmable Oscillator

The SIT9005ACR2G-XXSD is an ultra-sensitive programmable oscillator with a frequency range of 1.9200 GHz to 2.1435 GHz. It is a small form factor and cost-effective solution for an array of applications. Examples of the type of applications this programmable oscillator is used for include set-top boxes and electronic warfare receivers. The SIT9005ACR2G-XXSD is also used to drive various microprocessors and building various communication systems.

Why Use Programmable Oscillators

Traditional oscillators, or resonator-based design, are designed for frequency stability and stability over time. Programmable oscillators possess the same properties, but offer the flexibility of adjusting the frequency. This ability to adjust and control the frequency of a circuit or device can be advantageous depending on the application.

For example, for applications such as set-top boxes, programmable oscillators typically allow for better performance when it comes to responding to customer demands or changes. Oscillators that are not programmable may require the user to come up with their own manual adjustments, which could lead to additional time and expenses.

Working Principle of Programmable Oscillators

At the heart of every programmable oscillator is its oscillator core, also known as a voltage controlled oscillator (VCO). The VCO is the key component of any oscillator circuit, and is responsible for generating an oscillating signal. This signal is determined by the voltage applied to the VCO. By way of an array of components, the feature or capability of controlling the signal frequency of the oscillator can be achieved.

The main feature of VCOs is the ability to modify their frequency via control voltage. In general terms, it can be said that the control voltage, more often voltage range, of the VCO determines the frequency of the output signal. This means that by changing the voltage range of the VCO, the frequency of its output can also be altered.

The primary benefit of programmable oscillators is the ease with which the user can adjust the output frequency by changing the voltage range of its VCO. This is beneficial for applications where frequency stability and time stability are desired but precise adjustment to the signal is not required.

Conclusion

The SIT9005ACR2G-XXSD is an example of a programmable oscillator which is generally used for set-top boxes and electronic warfare receivers. It is a small form factor, cost-effective solution for an array of communications systems. Programmable oscillators offer the flexibility of adjusting the frequency by changing the voltage range of its VCO. This is beneficial for applications where frequency stability and time stability are desired but precise adjustment to the signal is not required.
