CY22800FXC-033A is a clock generator designed by Cypress Semiconductor company for applications where its low jitter, wide operating frequency ranges, low supply voltage and low power consumption are required. It is typically used in networking, storage, and communication systems, as well as industrial, medical, and test instrumentation. This device has a clock input frequency range from 6.25 MHz to 801 MHz and an output frequency range from 0.001 MHz to 133 MHz.

The CY22800FXC-033A clock generator integrates a PLL, low-jitter clock synthesizer, 12 analog-controlled adjustable outputs, and 12 fixed-frequency, 3.2V outputs into a single 5mmx5mm TQFP package. The PLL includes an on-board VCO and (Fractional-N) divider with 5-bit digital-to-analog converter (DAC). The PLL also supports non-integer frequency synthesis, allowing high-precision adjustments, and supports output clocks with symmetrical or asymmetrical duty cycles.

CY22800FXC-033A can refer to either the whole clock generator IC, or just the PLL. Either way, the PLL is used in the same fashion. The inputs to the PLL are the reference clock and the input frequency. The output of the PLL is the output clock, which is precisely different from the reference clock in frequency and phase. The PLL uses a Feedback Divider, which adjusts the output frequency by a fixed ratio relative to the input frequency. This ratio is determined by the value of the DAC and the VCO. The circuit also includes a charge pump, which produces a controlled current to adjust the VCO and reduce power consumption.

The main application of the CY22800FXC-033A is in communications systems, where there is a need for precise timing and reliable performance over a wide range of frequencies. Networks often require an accurate and low-jitter clock generator, and the CY22800FXC-033A is designed to meet this demand. It is also used in storage and medical systems, as well as in industrial, scientific, and test instrumentation.

The CY22800FXC-033A is also useful for general-purpose timing applications, as it has a wide frequency range, low jitter, and low power consumption. The fixed outputs can provide at-a-glance information regarding frequencies and other timing operations, making it an ideal choice for all types of timing applications, including data acquisition, signal processing, and video processing.

In summary, the CY22800FXC-033A is a clock generator designed for use in a variety of applications. It is ideal for high-precision communications systems, storage and medical systems, industrial, scientific, and test instrumentation, as well as general-purpose timing applications. Its low jitter, wide operating frequency range, low supply voltage, and low power consumption make it an ideal choice for many system designs.
