Working Principle

The CY22381SXC-212T device is based on an on-chip, quad-phase digital phase-locked loop (PLL), which allows the device to provide a variety of clock outputs from multiple sources. The architecture is capable of generating high-frequency output clocks from low-frequency inputs.

It follows a typical PLL structure, with a phase-frequency detector (PFD), a charge pump, a voltage-controlled oscillator (VCO), and a set of frequency dividers. The PFD measures the phase difference between the reference clock input and internal feedback clock and adjusts the charge pump current accordingly.

The charge pump is then used to control the VCO, while the frequency divider divides the output of the VCO such that the initial input reference frequency is reproduced at the output in a desired multiple of the original frequency. The device also features integrated frequency synthesizers and voltage controlable frequency dividers.

Conclusion

The CY22381SXC-212T is a highly integrated, low power clock generator device that can be used in a wide range of low power, high speed applications. Its on-chip PLL structure enables the generation of high-frequency output clocks from low-frequency inputs, and the integrated frequency synthesizers and voltage controlable frequency dividers allow for the generation of customized frequencies.
