Working Principle

The SI5342A-C05089-GM operates on the principle of voltage-controlled oscillators (VCOs). The device is based on the type of PLL in which the output frequency is controlled by a voltage-controlled oscillator. The device consists of an input divider, an FLL loop filter, a VCO and an output divider. The input divider receives an input frequency and divides it down to a voltage-controlled frequency range. The output of the input divider is then passed through the FLL loop filter, which is used to shape the frequency response of the device. The filtered signals are then fed to the VCO, which is capable of generating an output frequency of up to 20GHz, depending on the input frequency. Finally, the output of the VCO is directed towards the output divider, which further reduces the frequency down to the desired output frequency. The output divider then provides the output frequency to the necessary application.

Conclusion

In conclusion, the SI5342A-C05089-GM is a versatile frequency synthesizer designed for a range of applications, including satellite communications, military communications, radar and more. The device is based on the VCO design principle, where an FLL loop filter and an output divider serve to shape the frequency response and generate the desired output frequency.
