Programmable Oscillators

Programmable oscillators are multi-functional electronic components that provide a wide range of features aimed at enhancing an audio/video system\'s performance. In addition to providing an oscillator, programmable oscillators can also include features such as frequency selection, phase noise control, harmonic distortion control, and temperature compensation. With such features, they are ideal for a variety of applications, including cellular radio and audio/video applications.

Among programmable oscillators, SIT9005ACU2H-18NJ are particularly attractive, given their versatility. The SIT9005ACU2H-18NJ is part of Maxim Integrated’s 7+-bit programmable fractional clock oscillator family, featuring a 0.45pF crystal load capacitance, a 0.75V output voltage, and a 50 MHz clock frequency with a frequency error of ·2kHz. It is designed for applications that require high accuracy, and it uses a PLL (Phase Lock Loop) scheme, which enables it to dynamically select the most accurate output frequency. In addition, it has a toggle mode, which allows the output frequency of SIT9005ACU2H-18NJ to be changed on the fly.

Furthermore, the SIT9005ACU2H-18NJ can be used in applications that need to alter the output frequency without having to use expensive and time-consuming re-designs. It is ideal for any application that requires high accuracy OCXO (Oven Controlled Crystal Oscillator), as well as applications such as broadcast TV, high-speed ADC/DAC systems, and programs such as GPS. With its programmability, the SIT9005ACU2H-18NJ can also be used for applications such as frequency synthesis applications, or used in medical imaging systems.

In terms of its working principle, SIT9005ACU2H-18NJ utilizes a feedback loop in order to achieve frequency accuracy and stability. The feedback loop consists of two components, which are an oscillator circuit and a frequency control loop. The oscillator circuit produces a frequency signal depending on the voltage supplied to it and its crystal load capacitance. This signal is then filtered to a usable level and sent out as the output frequency of the oscillator. Meanwhile, the frequency control loop monitors the output frequency and uses a programmable voltage divider to adjust the voltage supplied to the oscillator circuit. This helps ensure the accurate and reliable output frequency is maintained.

Overall, SIT9005ACU2H-18NJ is an ideal choice for applications that require frequency accuracy and stability. Its programmable features make it a cost-effective solution for a wide range of applications. It is also an excellent solution for applications that require frequency synthesis ability. Its frequency control loop, coupled with its crystal load capacitance, helps make the SIT9005ACU2H-18NJ an ideal component for applications that require high accuracy and reliability.
