The CY22800FXC-026A clock generator is an ultra-low jitter and variable frequency clock driver that allows designers to spread the oscillator’s frequency spectrum to a wider area for improved system noise immunity. The zero delay buffer implementation provides low delay resulting in ns of reduced clock to output propagation delay. The alternative configuration of this clock generator provides a Low Jitter Spread Spectrum output. This spread spectrum output allows the device to be used in a variety of applications.
Application Field
- Guidance systems
- Telecommunication systems
- Networking systems
- High frequency applications
- Wireless systems
- Equipment embedded systems
- Industrial control systems
The CY22800FXC-026A is used in a wide variety of applications, particularly where high frequency and reduced jitter is important. The device is especially suitable for applications requiring longer “string” output clocks such as those used in frequency or phase synchronization. This device is also found in clocking instrumentation for triggering and synchronizing signals. By providing multiple output clocks from one oscillator, the device saves board space and wiring complexity.
Working Principle
The CY22800FXC-026A is a high-precision clock generator that is designed to spread the frequency spectrum of its oscillator output over a wider area. This is accomplished by loading the voltage controlled oscillator (VCO) with a resistor-capacitor (RC) filter, which acts to reduce the oscillator’s resolution. The reduction in resolution leads to a wider spread of signal frequencies, which in turn results in reduced jitter.
The CLKOUT frequency is determined by a reference signal applied to the device’s REFCLK pin. This signal is then processed by a digitally-controlled oscillator (DCO) in the device, with the resulting oscillator output being passed through an RC filter to generate the multiple output clocks. The output clocks can then be used as required by the system.
In addition to spreading the frequency spectrum of its oscillator output to reduce jitter, the CY22800FXC-026A also provides a Low Jitter Spread Spectrum output. This output provides a low-jitter, highly regulated clock that is suitable for use in high-frequency, low-noise systems. The Low Jitter Spread Spectrum output is generated using a combination of digital-control and analog components, which are able to reduce jitter to a minimum.
The CY22800FXC-026A is also able to provide multiple output clocks from a single oscillator. The device consists of three independent output clocks, each of which can be individually programmed to support various applications. The variable frequency allows for easy clock synchronization and the ability to control each output frequency ensures that the system operates with maximum efficiency.
The CY22800FXC-026A is a highly reliable clock generator that provides exceptional performance in a variety of applications. Its ability to spread the spectrum of its oscillator output over a wide area, combined with its ability to provide multiple output clocks from a single oscillator, makes it an ideal choice for designers looking to reduce system noise and improve overall performance.
