PXIe定时同步模块设计

PXIe Timing and Synchronization Module Design

该文介绍了利用高频率精度和稳定性的恒温晶体振荡器、超低噪声时钟抖动消除器LMK04828、FPGA K7C325T等设计基于PXIe的定时模块的方法。定时模块通过PXI触发总线、星形触发线和高稳定性的时钟,提供精确的触发和信号路由,用于系统定时和同步。用于PXIe数字化仪、任意波形发生器、量子计算机等,实现多模块间、多系统间精密的延时与同步控制。

The article describes the design method of Timing module based on PXIe using thermostatic crystal oscillator with high frequency precision and stability,ultra-low noise clock jitter cleaner LMK04828 and FPGA XC7K325T.The Timing module provides precision trigger and signal routing via PXI trigger bus,star trigger and high stability clock for timing and synchronization for system.Used for digitizer,arbitrary waveform generator,quantum computer and other instruments to realize precise delay and synchronization control between multiple modules and multiple systems.
