Introduction to Programmable Oscillators

Programmable oscillators are oscillator circuits designed to produce an output signal at a wide range of frequencies. They are often used in applications where a precise and adjustable frequency is required. For example, in radio transmissions, the oscillator needs to be tuned to the exact frequency of the radio transmitter in order to maintain consistent communication.Programmable oscillators are typically made up of two main parts: a phase locked loop (PLL) and a frequency synthesizer. The PLL is the main component of a programmable oscillator, as it allows the user to adjust the output frequency by entering the desired frequency in the PLL\'s control. The frequency synthesizer is a device which creates the digital signal that is used to control the PLL. Once the desired frequency has been entered, the synthesizer translates the digital signal into an analog signal, which is then sent to the PLL for adjustment.The SIT9005ACR1G-28SI is an example of a programmable oscillator. This particular oscillator is designed for use in mobile communications and wireless data applications. This oscillator uses a digitally controlled PLL to synthesize an output signal with a frequency range of 24MHz to 5.6GHz. The PLL also has a control range of 10kHz to 10MHz in steps of 1kHz.

SIT9005ACR1G-28SI Application Field and Working Principle

The SIT9005ACR1G-28SI programmable oscillator is designed to be used in a wide range of mobile communications and wireless data applications. This includes mobile phones, wireless modems, radar, satellite communications, and more. The oscillator is specifically designed to meet the needs of data transmission in the wireless industry. The working principle of SIT9005ACR1G-28SI is based on the digital synthesizer, which will generate the digital signal to be sent to the PLL. The PLL then amplifies the signal and adjusts the frequency to match the desired frequency. This adjustment is done through an input capacitor that allows the user to adjust the frequency range from 10kHz to 10MHz in steps of 1kHz. The SIT9005ACR1G-28SI also features some advanced functionality, such as jitter attenuation and fast lock time. The jitter attenuation feature means that the oscillator is designed to reduce random noise and other fluctuations in the signal. This is important for applications such as GPS which require precise timing. The fast lock time means that the oscillator can quickly adjust to changes in the frequency, making it ideal for applications which require quick response times.

Conclusion

The SIT9005ACR1G-28SI is a versatile programmable oscillator that can be used in a wide range of mobile communications and wireless data applications. This oscillator is designed to meet the needs of the wireless industry, with features such as jitter attenuation and fast lock time. It is also capable of a wide frequency range of 24MHz to 5.6GHz, with a control range of 10kHz to 10MHz in steps of 1kHz. This makes the SIT9005ACR1G-28SI a great choice for applications that require precise control of the output signal frequency.
