Programmable Oscillators

Programmable oscillators are devices that allow for the frequency and other parameters of an output signal to be easily adjusted for a variety of applications. They are widely used in different industries such as automotive, aerospace, industrial, medical, and military applications. One of the most commonly used programmable oscillators is the SIT9005ACA2H-18DE oscillator.

SIT9005ACA2H-18DE Programmable Oscillator

The SIT9005ACA2H-18DE is a high performance, low cost programmable oscillator. It features differential outputs, zero glitch design, and requires no external components. The SIT9005ACA2H-18DE is capable of generating frequencies from 122.88MHz to 388.23MHz and offers very low active power consumption. It is ideally suited for a variety of applications in automotive, aerospace, industrial, medical, military, and general applications, and provides the flexibility to easily configure a frequency depending on the application.

Application Field

The SIT9005ACA2H-18DE is designed for use in high performance applications requiring a wide frequency range. Some of the applications this oscillator is used for include frequency multiplication, clock generators, frequency synthesizers or for use as a clock source for communication applications such as Ethernet, USB and IEEE 1394. Additionally, the oscillator is also well suited for use in medical imaging or instrumentation, digital television receivers and automotive applications.

Working Principle

The SIT9005ACA2H-18DE works using a programmable voltage-controlled oscillator (VCO) based architecture. A VCO circuit is controlled by a voltage and produces frequencies that change with the applied voltage. The SIT9005ACA2H-18DE takes this principle and combines it with an integrated frequency-locked loop (FLL) to provide a stable and highly accurate output frequency. The FLL is constantly monitoring the output frequency and adjusting it if it drifts away from the desired frequency set by the user. This allows the oscillator to produce a stable and highly accurate frequency.

Conclusion

The SIT9005ACA2H-18DE is a high performance, low cost programmable oscillator designed for use in various applications such as automotive, aerospace, medical and industrial applications. It features differential outputs, zero glitch design and a wide frequency range, ensuring high accuracy and stable output. The oscillator operates using a voltage controlled oscillator and frequency locked loop to provide a highly accurate frequency with low active power consumption.
