Programmable Oscillators

Programmable oscillators are highly versatile electronic devices, able to provide a variety of frequencies in different situations and applications. An example of one of these oscillators is the SIT8009AI-21-XXX-000.FP000. This device is a particular type of voltage controlled crystal oscillator (VCXO) oscillating with a range of frequency from 2.0 to 3.6 GHz. Its programmability allows operators to change its frequency in a highly precise manner, making it a perfect fit for more advanced applications.

In order to understand the workings of the SIT8009AI-21-XXX-000.FP000, it is important to explain fundamental conceps about crystal oscillators.

A crystal oscillator is an electronic device utilizing an oscillating crystal as the main component. The stability and accuracy of oscillation in these circuits is higher than others due to the stability of a quartz crystal. The addition of electronic components like resistors, capacitors, transistors and diodes, will determine the accuracy, stability and other characteristics of the oscillations.
In the SIT8009AI-21-XXX-000.FP000, a quartz crystal begins the process of oscillations, and the circuit surrounding it amplifies and refines the signal. A voltage-control pin allows an external voltage to control the frequency of oscillations in a very precise way. This way, the frequency of this device is typically around 200 ppm, which is extremely precise for many applications.

For example, in communication applications, timing signals need to be exact. A VCSO with a wide frequency range and tight stabilities can provide the necessary accuracy to maintain proper communication protocols. Due to its programmability, this device is ideal for such contexts because the frequency can be easily changed externally. This can be used to set the frequency according to the needs of the communication system.

In general, the SIT8009AI-21-XXX-000.FP000 is an excellent choice for applications that require precise frequency control. Its wide range of frequencies, wide voltage range and precision makes it a great fit for communication applications, as well as other contexts where precise intervals of time may be important. As a VCSO oscillator, it provides great stability and accuracy, making it a reliable choice for many applications.
