The CY2309CZXI-1H is a clock generator and frequency synthesizer that is capable of generating high quality, low phase noise clocks over a wide frequency range. It is a fully integrated device that includes a voltage-controlled oscillator, a PLL and a frequency synthesizer in a single package. The CY2309CZXI-1H receives a differential or single-ended reference clock input and generates any desired high-precision output frequency with very low phase noise, jitter and spread spectrum. It is designed to operate under a single 2.5V supply, requiring low power and providing maximum performance.

The CY2309CZXI-1H\'s primary use is to generate test clocks for high-speed digital applications, such as memory and interface testing, as well as a wide variety of embedded system and communications applications. It can also be used in medical, broadcasting and military applications. The device can be used with single-ended reference clocks up to 1.4GHz and with LVPECL/LVDS reference clocks up to 3.2GHz. The output of the CY2309CZXI-1H can be programmed to any frequency between 100MHz and 1GHz.

The CY2309CZXI-1H has an on-chip PLL which enables it to convert the input reference frequency to an accurately tuned output frequency. It also provides a spread-spectrum clock output, which reduces EMI (noise) and can be used for frequency hopping. The spread-spectrum signal can be programmed using different step sizes and center frequencies, allowing a wide range of optimization options. The device also has an on-chip voltage-controlled oscillator (VCO) with a tuning range of 90MHz to 1.2GHz.

The CY2309CZXI-1H\'s frequency synthesizer can generate any desired frequency, including clock frequencies with low-phase noise and jitter. The on-chip synthesizer improves clock jitter performance and noise reduction over and above what a PLL can provide. It is also optimized for low-voltage operation, making it suitable for low-power applications. With its wide range of features and low-power operating modes, the CY2309CZXI-1H is an ideal solution for a wide range of clock and frequency generator applications.

In summary, the CY2309CZXI-1H is a clock generator and frequency synthesizer, able to generate high quality clocks over a wide frequency range. It provides a differential or single-ended reference clock input and a wide range of frequency outputs with low phase noise, jitter and spread spectrum. The on-chip PLL and synthesizer also provide optimized low-voltage operation, making it ideal for a variety of clock/frequency generator applications.
