Programmable Oscillators are components used in electronic circuits to provide an oscillating output signal at a variety of frequencies. They can be programmed with a specific frequency, or adjusted over a range. The SIT9005ACT2H-25DB is a programmable oscillator used in a variety of applications. This article will explain the application field and working principle of this oscillator.

Application Field

The SIT9005ACT2H-25DB programmable oscillator is commonly used in a variety of applications such as telecommunications, broadcast, wireless, medical, and more. Its frequency range is from 75MHz to 250MHz, and can be programmed to within <1% accuracy by a user generated program. The oscillator also has a low phase noise and fast settling time, making it a good choice for applications requiring high frequency stability.

The SIT9005ACT2H-25DB is also commonly used in precision frequency control applications. Its low phase noise and fast settling time make it ideal for relieving jitter and phase noise issues in communication systems and other applications that require precise frequency control. The oscillator is also a good choice for applications where low power consumption is required. The SIT9005ACT2H-25DB typically consumes less than 1 mw of power and is available in both 3.3V and 5V varieties.

Working Principle

The SIT9005ACT2H-25DB programmable oscillator is based on a dual Gate MOSFET (Metal–Oxide–Semiconductor Field Effect Transistor) design. It works by creating an alternating current between the drain and source of the MOSFET. The current is then passed through an inductor to create an oscillating signal. The signal is then split into two paths, one going to the user-programmable frequency adjustment potentiometer, and the other going to the output terminal. By adjusting the potentiometer, the frequency of the oscillator can be adjusted to a desired frequency.

The SIT9005ACT2H-25DB also has low jitter characteristics, which make it a good choice for timing and synchronization applications. The oscillator is available in two different packages: a 2mm x 2mm 8-Pin QFN and a 2.5mm x 2.5mm 10-Pin MLF. It can be used with a variety of other components such as frequency dividers, mixers, filters, and more.

Conclusion

The SIT9005ACT2H-25DB programmable oscillator is a versatile component capable of providing an oscillating signal at a variety of frequencies. It is commonly used in telecommunications, broadcast, wireless, medical, and other applications. It is also commonly used in precision frequency control applications due to its low phase noise and fast settling time. Its dual Gate MOSFET design and low jitter characteristics make it a great choice for timing and synchronization applications. The SIT9005ACT2H-25DB is available in two packages and can be used with a variety of other components.
