Programmable oscillators are electronic circuits used in a variety of electronic devices, including consumer products and industrial systems. They offer great flexibility in the frequency range, which makes them especially attractive for applications requiring wide frequency ranges, from low frequency telecom networks to high frequency radio and broadcast applications. One such programmable oscillator is the SIT9005ACL2G-33SA. This article will explore the application field and working principle of this oscillator.

1 Application Field

The SIT9005ACL2G-33SA is a voltage controlled oscillator (VCO) designed for the wireless telecommunications industry. It offers the flexibility of changing the frequency range without the need for a frequency multiplier, which makes it an ideal choice for cellular base stations, wireless systems and other applications requiring frequency agility. Its default frequency range covers 300MHz to 6GHz, however it can also be custom configured to operate in other frequency ranges. It offers low phase noise and excellent stability, making it suitable for high performance applications such as satellite communications and other can applications requiring superior phase-noise performance. The SIT9005ACL2G-33SA also has a built-in phase-lock-loop (PLL). This enables it to be used in phase-locked loop (PLL) configurations.

2 Working Principle

The SIT9005ACL2G-33SA is a dual PLL VCO that operates with a supply voltage of 3.3 V. It includes both an analog VCO and a digital PLL, allowing for a wide frequency range that is adjustable to meet the application’s requirements. The oscillator utilizes a voltage controlled oscillator (VCO) to generate a signal in the range of 300MHz to 6GHz. The VCO is tuned by an external voltage, which is often supplied by a voltage-controlled oscillator (VCO) frequency divider circuit (FD). This allows the frequency range to be adjustable without the need for a complex frequency multiplier circuit. The VCO’s output is then fed into the PLL, which modulates the output of the VCO in response to an external reference clock. This allows the VCO to be tuned to a precise frequency accurately. The PLL also allows the VCO to operate multiple functions simultaneously, such as frequency hopping, frequency selection, and timing.

3 Conclusion

The SIT9005ACL2G-33SA is a reliable and versatile programmable oscillator that offers an excellent frequency range and superior performance for applications requiring frequency agility. Its dual PLL architecture and wide frequency range enable it to be used in multiple functions simultaneously.

In summary, the SIT9005ACL2G-33SA is the perfect choice for applications that require a wide frequency range. It offers excellent frequency agility, low phase noise, and an adjustable frequency range that can be customized to meet the specific application requirements. It is a versatile and reliable programmable oscillator for wireless telecommunications, industrial systems, and other applications requiring multiple functions and excellent performance.
