The CDCVF2505DR is an advanced, low jitter clock generator that is available in reliable 14-pin QFN packages. It is a complete clock generator with an integrated voltage-controlled oscillator (VCO), phase-locked loop (PLL), and frequency synthesizer. This device has been designed to provide reliable, low jitter clock generation in a small form factor. The CDCVF2505DR is used for applications such as high-speed communication and computing systems, high-end servers, and storage systems.

Application Field

The frequency range of the CDCVF2505DR is from 10 MHz to 1.5 GHz. It is designed to provide appropriate applications with reliable low jitter output of low to medium clock frequencies. It can provide low jitter clock outputs for high-speed communication and computing systems, high-end servers, storage systems, and optical transceivers. In addition, this device is also suitable for jitter attenuation, test and measurement systems, and other applications requiring high-accuracy clocks.

Working Principle

The CDCVF2505DR includes a voltage-controlled oscillator (VCO), a phase-locked loop (PLL), and a frequency synthesizer. The PLL stage consists of a phase detector, loop filter, and a voltage-controlled crystal oscillator. The phase detector ensures the stability of the VCO’s frequency and phase lock by comparing the output of the VCO with an external reference clock. The loop filter filters out any unwanted noise from the system and provides a cleaner output. The frequency synthesizer allows for the generation of a wide range of clock frequencies with a high level of accuracy even when the application environment changes. At the output of the device, a fault detector monitors the system for any oscillator-related issues.

The CDCVF2505DR offers a wide range of features such as slew rate control, spread spectrum control, output enable/disable and hot-swap control. These features allow for dynamic control of the generated output frequencies, making it suitable for a wide range of applications. The device is available in a 14-pin QFN package and is RoHS compliant.

The CDCVF2505DR is a reliable, high-performance clock generator that is suitable to meet the demands of a wide range of industrial, communications and computing applications. Its flexibility and low-jitter output make it an attractive choice where reliable clock signals are required.
