ADC测试中同源时钟分析与解决方案

Analysis and Solution of Homologous Clock in ADC Test

ADC测试中,使用同源时钟进行ADC数据采集并对静态指标进行分析时,出现严重的丢码现象,导致静态指标测试结果严重超差。基于此问题及引申出的其他问题进行相关分析,以此为基础从理论分析到实物验证,解决了同源时钟静态指标测试问题。

In the ADC test,when using the homologous clock to collect ADC data and analyze the static indicators,there is a serious loss of code,which leads to serious out of tolerance of the static specifications test results.Based on this problem and other problems,this paper makes a correlation analysis,and on this basis,from theoretical analysis to physical verification,solves the problem of homologous clock static specifications test.
