It can be employed in battery-powered applications such as wireless mouse, smoke detectors, remote control toys, meters and home appliances.

Working Principle

The CY22050KFZXI is a frequency synthesizer with an integrated phase-locked loop (PLL) and digital clock generator. The PLL is responsible for generating the clock signal by locking in to a desired frequency and maintaining a steady local clock based on that frequency. It also adjusts the output frequency to match the input signal, thereby ensuring a clean and reliable clock signal.

The frequency synthesizer consists of an analog-to-digital converter (ADC), a digital-to-analog converter (DAC) and a voltage controlled oscillator (VCO). The ADC is used to convert an analog signal into a digital signal, while the DAC is used to convert the digital signal into an analog signal. The VCO is then used to control the frequency of the output signal, by changing the voltage applied to it. This allows the output frequency to be adjusted quickly and accurately.

The output voltage of the DAC is then monitored by the PLL and feedback is used to adjust the output frequency. This synchronization is achieved by monitoring the phase difference between the input signal and the output signal and adjusting the output signal accordingly. This allows the output frequency to be adjusted quickly and accurately in order to maintain a stable, clean clock signal.

In addition, the CY22050KFZXI also offers a variety of other useful features. It has frequency range up to 2.4 GHz , with a frequency resolution of 0.1 Hz. It has an impressive power consumption of 18 mW in standby mode,as well as a range of low power modes for battery operated applications. It also has a CMOS output stage for low-noise and low-power operation.

The CY22050KFZXI from Cypress Semiconductor is a highly integrated and versatile solution for applications that require reliable clock signals and PLLs. Its low power consumption and a range of features make it an ideal choice for a wide variety of applications, from consumer electronics to industrial and automotive applications.
