Clock Generators, PLLs, Frequency Synthesizers: CDCVF857RHAT Application Field and Working Principle

Clock generators are used to generate clocks and signal that are used to synchronize other electronic components in a system. Clock generators prove to be necessary when dealing with advanced communication systems and other signal processing systems. An example of a clock generator would be the CDCVF857RHAT, which this paper will explore further by discussing its applications and its working principles.

CDCVF857RHAT Applications

The CDCVF857RHAT is a highly integrated clock generator that can generate frequencies up to 250 MHz and is suitable for diverse applications and systems. Its synthesized frequencies and outputs can be tailored for use in various systems such as communication devices and data transmission across various channels. Specifically, the CDCVF857RHAT is employed in applications such as SERDES interface communication, high-speed data transmission, video processing systems, and 3G/4G communication systems.

Working Principle

There are two basic categories of clock generator, namely, Phase-Locked-Loop (PLL) and a Frequency Synthesizer. The CDCVF857RHAT is actually a combination of a PLL and frequency synthesizer and it is designed to generate highly accurate and frequency-configurable signals. The main difference between a PLL and a Frequency Synthesizer is that a Frequency Synthesizer generates frequencies in discrete jumps while a PLL offers a continuous range of frequencies.

The working principle of the CDCVF857RHAT is similar to both PLL and Frequency Synthesizer. The clock generator utilizes a voltage-controlled oscillator (VCO) with the help of a feedback circuit; the frequency of the signal generated by the VCO is then locked at the desired frequency by the PLL-based control circuitry. The output of the clock generator can be configured for either single-ended (S) outputs, or differentially-balanced (D) outputs. The output can also be adjusted from as low as 10 KHz to as high as 250 MHz.

Conclusion

The CDCVF857RHAT is an advanced clock generator that utilizes the latest technologies to generate highly accurate, frequency-configurable signals. It can generate frequencies up to 250 MHz and is suitable for applications such as SERDES interface communication and high-speed data transmission. The main difference between a PLL and a Frequency Synthesizer is that a Frequency Synthesizer generates frequencies in discrete jumps while a PLL offers a continuous range of frequencies. The CDCVF857RHAT combines the best of both technologies in order to perform its functions effectively.
