Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The industry of semiconductors is a technology-driven sector with an increasing demand for low-power and reliable products. This trend has created the need for improved clock/timing management solutions across all industry segments. To meet this need, semiconductor companies have developed advanced clock/timing products in the form of clock/timing-based integrated circuits. Among these products, the CDC586PAH is a notable example. This clock/timing-based integrated circuit is renowned for its low-power, reliable performance and versatility.

The CDC586PAH is a low-power, highly-flexible and versatile clock generator with random phase and frequency synthesis capabilities. It is suitable for application in various communications and broadcast markets, from base stations to satellite systems. The device is capable of providing four simultaneous clock outputs, each with independent phase, frequency, and duty cycle adjustment capabilities. Additionally, the CDC586PAH offers integrated frequency dividers and phase detectors, along with an adjustable power supply voltage (1.8 volts to 5.5 volts) to cater to multiple different applications.

The main purpose of the CDC586PAH is to generate a stable clock signal with precise timing and frequency of operation. The device employs two main technologies to achieve this goal: Phase Locked Loop (PLL) and Frequency Synthesizer (FS).

The Phase Locked Loop (PLL) is the component responsible for generating and looping in the frequency of the desired clock signal output. The frequency of the output clock is determined by the input frequency, the clock divider, the phase/frequency detector, and the charge pump. These elements work together to generate a clock frequency of the desired frequency through the internal feedback mechanism of the loop.

The Frequency Synthesizer (FS) is a component of the device responsible for fine tuning the clock signals. This component takes in a clock source and allows for precise adjustments in the frequency, phase and duty cycle of the clock. Usually, the FS consists of a phase-frequency detector, a charge-pump, a low-pass filter, and a voltage controlled oscillator (VCO). The VCO is the component responsible for generating tunable clock signals with adjustable phase and frequency.

The combination of the PLL and the FS enables the CDC586PAH to generate highly stable clock signals with precise timing and frequency. The device is designed to handle a wide range of frequencies, from kHz to GHz range, while maintaining the output accuracy and power consumption. In addition, the device offers flexible operation through its adjustable power supply, clock divide, and other on-chip features.

In summary, the CDC586PAH is a versatile clock generator with random phase and frequency synthesis capabilities.This device is suitable for a wide range of applications, from base stations to satellite systems. The device employs a combination of PLL and FS technologies to generate highly stable clock signals with precise timing and frequency. Lastly, the device offers a wide range of features, such as adjustable power supply, clock divide, and other on-chip features to meet the needs of different applications.
