The CDCVF2509APWR is a clock generator, phase locked loop (PLL) frequency synthesizer, designed to facilitate the design of clock-based systems with accurate and simple frequency generation. As a clock generator, this device generates clock signals at speeds up to 25GHz in a range of frequencies, with selectable output phase and skew delay. As a PLL, this device utilizes an internal VCO to phase track and generate non-standard frequencies. As a frequency synthesizer, this device is capable of generating and outputting frequencies from 1MHz to 25GHz over a wide voltage and temperature range.
CDCVF2509APWR Application Field
The CDCVF2509APWR’s broad range of frequency support and wide voltage and temperature range make it suitable for a variety of applications. It is commonly employed in optical transport systems, cable and satellite data systems, wireless communication systems, avionics, and defense. The CDCVF2509APWR is also employed in test and measurement systems, such as those used in engineering and production, and in research and development applications.
CDCVF2509APWR Working Principle
The CDCVF2509APWR works much like a conventional PLL frequency synthesizer. It has an input frequency, or reference clock, which is used to determine the output frequency. The device also has a VCO, which generates a frequency in response to changes in the reference clock. The output of the VCO is compared to the reference clock, and any discrepancy between the two will be corrected by the internal circuitry of the device. The comparison frequency between the reference and the VCO determines the accuracy of the frequency output.
In addition to the VCO, the CDCVF2509APWR is also equipped with a Phase-Locked Loop (PLL), which further enhances its frequency accuracy. The PLL uses a control voltage to integrate the frequency error, to settled more precisely on the target frequency. This also minimizes jitter in the output frequency. The PLL also provides a wide loop bandwidth which helps to ensure stability during frequency hopping and scanning.
The CDCVF2509APWR also includes an on-board Charge-Pump, which provides a reduced system complexity for the user by pre-charging the loop filter of the PLL. This eliminates the need for external loop filter components and allows for an easier system integration.
The CDCVF2509APWR also implements a low-jitter low-power Frequency Scaling Mechanism (FSM). This mechanism allows the user to scale down the output frequency of the device, depending on the application. This provides a great deal of flexibility for system designers, as the device can be used to generate a wide range of frequencies, all with low jitter.
The CDCVF2509APWR is also equipped with a Bypass Mode, which allows the device to be used without its frequency synthesizer if the application does not require a frequency synthesis capability. This mode eliminates the power consumed by the PLL, resulting in significant power savings.
Overall, the CDCVF2509APWR is an ideal solution for a wide range of clock-based systems. Its frequency synthesis capabilities, extended voltage and temperature range, and low-jitter FSM make it useful for a variety of applications. This makes it an attractive choice for system designers and users alike.
