The CY22381SXI-181T is a clock generator and phase-locked loop (PLL) frequency synthesizer that provides an accurate and reliable clock signal for a wide range of applications. It features an integrated PLL, an adjustable output clock rate and a VCO (voltage controlled oscillator) range of 600 kHz to 166 MHz. The on-chip PLL circuit can be used to synthesize clock signal frequencies from the on-chip oscillator or from an externally driven signal. The CY22381SXI-181T is ideal for applications such as digital signal processing, networking, and telecommunications.

The CY22381SXI-181T features a low power consumption, high frequency switching speed and an on-chip jitter reduction circuit that improves the accuracy and reliability of the clock signal produced. It uses a single-chip PLL circuit architecture to provide all the necessary clock generation and synchronization functions, and a built-in charge-pump circuit to increase the responsiveness of the PLL. The on-chip PLL has an on-chip programmable VCO counter and phase detector, an integrated voltage and temperature compensator and an automatic power reduction circuit to minimize power consumption.

The CY22381SXI-181T is capable of producing clock signal frequencies up to 166 MHz, with an adjustable clock rate and variable phase and duty cycle. The on-chip PLL is used to synchronize the output clock signal to an input reference signal, either from an on-chip oscillator or from an externally driven signal. The clock generator/synthesizer also features an optional integrated VCO capable of generating a frequency anywhere from 600 kHz to 166 MHz. It includes an adjustable low-frequency reference for the VCO and an adjustable VCO gain control for tuning the frequency. The on-chip VCO counter can be used to program the frequency of the output clock signal.

The CY22381SXI-181T is designed to operate over a wide temperature range, with an operating temperature of 0°C to 85°C. It is also fully EMI-compliant and supports a wide range of output real-time clock (RTC) frequencies, including those specified by the IEEE Standard 1588. Its high-speed programmable control pins allow for remote control of the device\'s programming and frequency setting, while its on-chip programmable VCO allows for further flexibility in the definition of the output clock signal\'s frequency and duty cycle.

Overall, the CY22381SXI-181T is a high-performance, low-power clock generator and PLL frequency synthesizer that can be used for a variety of applications. Its on-chip PLL circuit provides a simple and reliable solution for obtaining accurate and reliable clock signals for high speed digital signal processing, networking and telecommunications. Its low power consumption, high frequency switching speed and on-chip jitter reduction circuit help to make it an ideal solution for embedded systems, while its adjustable output clock rate, VCO range and programmable VCO counter make it an ideal solution for frequency and clock rate control.
