MMCM and PLL Dynamic Reconfiguration Application Note (XAPP888)
ثبت نشده
چکیده
This application note provides a method to dynamically change the clock output frequency, phase shift, and duty cycle of the mixed-mode clock manager (MMCM) for the Xilinx® 7 series, UltraScaleTM, and UltraScale+TMFPGAs. Similarly, the phase-locked loop (PLL) can be changed through the dynamic reconfiguration port (DRP). An explanation of the behavior of the internal DRP control registers is accompanied by a reference design that uses a state machine to drive the DRP, which ensures the registers are controlled in the correct sequence.

The circuit changes the clock frequency with a minim...
متن کاملA Multi-Objective Method for Network Reconfiguration (TECHNICAL NOTE)
This paper presents an algorithm based on multi-objective approach for network reconfiguration. Multiple objectives are considered for reduction in the system power loss, deviations of the nodes voltage and transformers loading imbalance, while subject to a radial network structure in which all the loads must be energized and no branch current constraint is violated. These three objectives are ...
متن کاملFeasibility study of presenting a dynamic stochastic model based on mixed integer second-order conic programming to solve optimal distribution network reconfiguration in the presence of resources and demand-side management
Nowadays, with the use of devices such as fossil distributed generation and renewable energy resources and energy storage systems that are operated at the level of distribution networks, the problem of optimal reconfiguration has faced major challenges, so any change in the power of this resources can have different results in reconfiguration. Similarly, load changes during the day can lead to ...
متن کاملDesign a Low-Jitter Clock for High-Speed Data Converters - AN800
High-speed applications using ultra-fast data converters in their design often require an extremely clean clock signal to make sure an external clock source does not contribute undesired noise to the overal dynamic performance of the system. It is therefore crucial to select suitable system components, which help generate a low phase-jitter clock. The following application note serves as a valu...
