Overview

The CPLL66-1600-2200 (CPLL) is a type of clock generator,phase-locked loop (PLL) and frequency synthesizer that is well-suited for use in a variety of applications. It combines the features of a basic clock/oscillator, digital frequency synthesizer, voltage controlled oscillator (VCO) and PLL to provide an accurate and reliable clock source. This device uses an externally managed dual high-speed PLL to allow the generation of a precise output clock frequency from an input clock whose frequency is only approximately known. This dual PLL architecture enables fast clock frequency adjustment for applications requiring higher level of accuracy.

Applications

The CPLL66-1600-2200 is designed for use in applications where stable and precise clock frequencies are required. Typical applications include high reliability clock distributions such as aerospace, avionic and maritime systems, since these applications often require higher clock accuracy and frequency control. Other applications include baseband signal processing, local area network (LAN) and wide area network (WAN) clock synchronization and wireless cellular networks.

Working Principle

The operating principle of the CPLL66-1600-2200 is based on a phase-locked loop (PLL). A PLL is a type of feedback control system that controls the output frequency of a signal using a signal in a feedback loop, such that the output frequency is kept in sync with the signal in the feedback loop. In the case of the CPLL66-1600-2200, the input signal is the reference clock, and the output signal is the precise clock signal. At the heart of the CPLL66-1600-2200 is a dual high-speed PLL, which can be externally managed for precise frequency control. The dual PLL works by measuring the difference between the reference clock and the output clock, and generating a corrective signal that can be used by the PLL to adjust the frequency of the output clock. This corrective signal is generated by a phase detector, which uses the phase difference between the two signals to generate an error voltage that can be used to adjust the output frequency. The frequency of the output clock is then adjusted accordingly until the difference between the reference and output clock is within a certain tolerance. The CPLL66-1600-2200 also features frequency-tunable gain control logic, which is used to control the accuracy of the output clock. This feature comprises a phase-locked loop detector, phase-locked loop frequency divider and phase-locked loop sample-and-hold circuit, which are all used to ensure the accuracy of the output clock frequency.

Conclusion

The CPLL66-1600-2200 is a dual high-speed, frequency synthesizer and PLL that is designed for use in applications requiring precise and stable clock frequency outputs. Its dual PLL and frequency-tunable gain control logic enable accurate frequency control, making it suitable for use in aerospace, avionics, maritime, baseband signal processing, LAN and WAN synchronization, and cellular networks.
