In RFID applications, it can be used to generate the frequencies required to power RFID tags.

In addition, the 841202AKI-245LFT can be used in satellite communications, where it can be used to generate frequencies that are used to transmit and receive signals. Similarly, it can be used in machine-to-machine (M2M) applications, such as telemetry and industrial control systems.

841202AKI-245LFT Working Principle

The 841202AKI-245LFT uses a synchronized direct digital synthesis (DDS) principle to generate and maintain the necessary signal frequencies. DDS is a type of frequency synthesis technique that converts digital signals into precise analog signals. A frequency reference is used to synchronize the DDS oscillator with the desired signal frequency.

The frequency reference is used as an input to control the oscillator, and the resulting signal frequency is determined by the frequency reference. The output frequency is also dependent on the oscillator\'s modulation capability. The output frequency of the 841202AKI-245LFT is then adjusted by fine-tuning its frequency reference.

In addition to its frequency reference, the 841202AKI-245LFT requires two power supplies: the VDD and V3.3 supply. The V3.3 supply provides the low voltage power required to support the low-voltage PLL operations. In addition, it supplies the VDDN voltage that is used to enable the on-chip device.

Conclusion

The 841202AKI-245LFT is a high-efficiency, low-voltage clock generator, PLL, and frequency synthesizer that offers reliable performance and a wide range of output frequencies. It is suitable for applications in the communications, wireless, and RFID markets, and works using the synchronized direct digital synthesis principle.
