摘要
针对越来越多的通道分布在多个板卡上的应用场景,设计了一种多板卡同步采样系统,并基于该系统提出一种多板卡相参时钟同步方法。该系统通过同步脉冲信号来替换系统参考时钟,减少了一半的时钟数量需求,简化了电路设计。硬件测试结果表明,模数转换(ADC)采样和通道同步性能均满足要求。
Aiming at the application scenario where more and more channels are distributed on multiple boards,a multi-board synchronous sampling system is designed,and a multi-board coherent clock synchronization method is proposed based on this system.The system replaces the system reference clock with a synchronous pulse signal,which reduces the number of clock requirements by half and simplifies the circuit design.The hardware test results show that the analog to digital conversion(ADC)sampling and channel synchronization performance can meet the requirements.
