CY24130ZXC-1 Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The CY24130ZXC-1 is a highly integrated clock generator, which provides a wide range of frequency synthesis capabilities for communications, computer systems and industrial control applications. It is based on a low-power, state-of the-art Silicon Germanium (SiGe) process technology, and represents an excellent solution for multi-frequency timing clock sources and synchronization systems.This highly cost-effective device provides a versatile, easy-to-use, single-chip solution to a wide variety of problems in clock generation. Its frequency range is 2.1875 MHz to 250 MHz, and it supports frequency multiplication ratios of x1, x2, x4, x6, x8 and x10. This highly integrated device offers complete SPI-programmable end-to-end settings for PLL loop, linear and dynamic frequency settings.The CY24130ZXC-1 supports a wide operating temperature range from –25°C to +85°C, guarding against frequency drift and accuracy over a sizable temperature range and providing desirable stability and uniformity across a variety of systems. In addition, it provides voltage and current support up to a maximum of 3.3 and 5V DC.The CY24130ZXC-1 integrates multiple features of importance to high-performance clock-generator applications, including:

• Programmable output dividers and PLL loop filters
• Low-noise, high-efficiency output clock buffer
• Self-test and start-up routines
• Phase-lock-loop (PLL) adjustment to expand frequency synthesis range and timing jitter performance
• Automatic power-management for power-saving modes

The working principle of the CY24130ZXC-1 is based on the Fractional-N Synthesizer (FNS) technique. By implementing this technique, the device can derive variable output frequencies from its 24.375 MHz reference clock input. This is made possible by using a phase accumulator and digitally controlled loop filter to create a reference signal that is proportional to the reference clock. This reference signal is then compared to a limited number of output clock waves, which form a fractional part of the reference signal. As the reference clock cycles, the phase accumulator accumulates a 24-bit phase difference that is then interpolated to determine which output clock frequency should be generated. The loop filter stores coefficients that can be updated to rapidly adjust the frequency of the loop to create new reference signals and hence, different output clock frequencies as required by the application. In addition to its excellent frequency synthesis feature, the CY24130ZXC-1 includes an on-chip voltage regulator and on-board temperature compensation for superior stability and accuracy over the operating temperature range. This ensures the device has a low frequency deviation and tight output-to-output channel matching for critical frequency-accuracy applications. To ensure the ease of use and flexibility, the device comes with user-programmable outputs, with each output having its own divider and output clock source options, along with phase-locked-loop (PLL) filter control options. It also includes various control registers to control frequency synthesis, such as VCO and output dividers, PLL loop filters as well as phase-locked-loop control options. The SPI-controlled registers may be read and changed using an external master to update output frequencies, and to provide automated software-controlled updates for fully automated frequency-control solutions.The CY24130ZXC-1 is extremely useful for applications that require high-accuracy clock generation, such as remote radio systems, home and commercial audio systems, and synchronous test-and-measurement systems. It is also useful for synchronizing and monitoring clock signals from multiple networks and systems, and for providing complete isolation from processor clock sources to ensure operation stability.Overall, the CY24130ZXC-1 is a highly integrated and flexible single-chip clock generator that offers an excellent solution for multi-frequency timing sources and synchronization systems. It is cost-effective, and provides complete SPI-programmable end-to-end settings with a wide operating temperature range and low power consumption. Its powerful features, such as the FNS frequency synthesizer, PLL loop implementation and on-chip voltage regulator and temperature compensation ensure high-accuracy clock generation and output stability. It also provides a versatile set of control registers to provide automated solutions and easy-to-use user-programmable outputs.
