Today, frequency synthesizers are widely used in various applications and serve as important sources of low phase noise and stable oscillation. The CY22150KFZXI is a high-performance, multi-channel frequency synthesizer designed to provide the optimal combination of low power consumption, low phase noise and accurate tuning performance, making it ideal for a broad range of frequency synthesis applications. This article will discuss the application fields and working principles of CY22150KFZXI.

Application Field

The CY22150KFZXI is a variable phase noise, low power, dual-channel frequency synthesizer. This synthesizer is suitable for applications such as wireless communications, point-to-point radio and satellite communication systems, base stations, and general-purpose frequency synthesizers. Other applications such as spread spectrum communication systems, microwave links, TV tuners, utility metering systems, GPS and navigation systems, sonar systems, industrial instruments and test equipment, and radio-astronomy receivers can also benefit from the CY22150KFZXI frequency synthesizer.

The CY22150KFZXI frequency synthesizer provides the optimal combination of low power consumption and low phase noise for a variety of frequency synthesis applications. This makes it an ideal component for applications that require low power consumption and low phase noise.

Working Principle

The CY22150KFZXI frequency synthesizer consists of a dual-channel phase noise, low power and high-performance frequency synthesizer. The two channels operate independently and are capable of up to 8 channels simultaneously. The device provides a wide range of frequency synthesizer solutions with low phase noise and high accuracy. When the device is powered on, it starts with an internal digital oscillator. The digital oscillator provides an accurate timing reference and generates a 16-bit division rate. This division rate is then used to generate the two channels’ ability to adjust the frequency synthesized.

To optimize the frequency synthesized, the internally generated division rate for each of the channels is adjusted according to the frequency division rate. The division rate is adjusted using a Notebook Frequency Lock Table (NFLT) written to the device from an external controller. The NFLT is a set of division factors that form the basis of the frequency division. The division rate can also be written from the internal controller to a software programmable division rate register. The division rate can be adjusted up or down depending on the desired output frequency.

The CY22150KFZXI frequency synthesizer also includes an internal active loop filter for tuning the division rate. This filter eliminates the need for external filtering, resulting in improved jitter performance and accuracy. The device also utilizes an internal automatic gain control (AGC) to provide optimal performance. The AGC adjusts the division rate depending on the noise and current conditions of the system.

Finally, the device is designed to work in both single-ended and differential modes. The single-ended mode allows the device to tune the output frequency while the differential mode allows the output frequency to be tuned to two different frequencies simultaneously. This allows the device to operate in applications where multiple frequencies are required.

Conclusion

The CY22150KFZXI is a high-performance, low power, dual-channel frequency synthesizer that is suitable for a wide range of frequency synthesis applications. This device provides an optimal combination of low power consumption, low phase noise and accurate tuning performance. It features an internal active loop filter for tuning the division rate and an internal automatic gain control for optimal performance. The device is also capable of running in single-ended or differential modes for applications requiring multiple frequencies.
