PI6CEQ20200LIE Application Field & Working Principle

PI6CEQ20200LIE is a clock/timing application-specific IC designed to provide precision phase frequency and phase angle synchronization among two or more clock domains. In order for accurate phase matching in a multiple clock domain system, PI6CEQ20200LIE measures and adjusts the clock signals\' phase and parameters such as duty cycle, skew, and jitter.

PI6CEQ20200LIE is a system-on-chip solution that includes an embedded phase locked loop (PLL), phase adjustment hardware, and a number of programmable digital functions. It also includes a programmable reference signal generator, multiple clock signal detectors, and a programmable digital control processor. The PI6CEQ20200LIE is an ideal solution for synchronizing and controlling large clock domains in systems with multiple clock domains, such as communication, signal processing, imaging, and video.

The PLL circuit in PI6CEQ20200LIE is used to synchronize the multiple clock domains and provide precise phase synchronization with minimal jitter and skew. It is also used to regulate the duty cycle of the clock signals, and to adjust the frequency of the clock signals if required. The phase locked loop uses a reference signal generator to provide an accurate frequency reference, which is then fed into the PLL and compared with the input clock signals. If a difference is detected, the PLL will adjust the frequency of the output clock signals to synchronize them with the reference signal.

In addition to the PLL, PI6CEQ20200LIE also includes a programmable digital control processor. This processor is used to monitor and analyze the performance of the clock signals and make adjustments as needed. The processor can also be used to detect events such as low-power consumption or voltage levels, and then make a decision whether to adjust the clock signals or not. The processor can also be used to control the phase matching and synchronization of the clock signals.

Finally, PI6CEQ20200LIE includes several programmable digital functions. These functions include the ability to switch between multiple clock signals and to adjust the frequency of each signal as needed. They also include the ability to adjust the duty cycle of each signal, which can be used to match the signals with each other for improved performance. Additionally, these functions also include the ability to control and measure jitter, as well as to monitor and limit the number of clock edges.

In summary, the PI6CEQ20200LIE is an ideal system-on-chip solution for providing precision phase frequency and phase angle synchronization between multiple clock domains. It includes a PLL circuit to synchronize the clock signals and a programmable digital control processor to monitor and adjust the clock signals as needed. Additionally, it includes programmable digital functions that allow for switching between multiple clock signals, adjusting the frequency of each signal, adjusting the duty cycle of each signal, and monitoring and limiting the clock edges. With these features, the PI6CEQ20200LIE is a great solution for large clock domains in communication, signal processing, imaging, and video systems.
