BGA CHIP PLACEMENT AND ROUTING RULE
BGA是PCB上常用的组件，通常CPU、NORTH BRIDGE、SOUTH BRIDGE、AGP CHIP、CARD BUS CHIP…等，大多是以bga的型式包装，简言之，80﹪的高频信号及特殊信号将会由这类型的package内拉出。因此，如何处理BGA package的走线，对重要信号会有很大的影响。
通常环绕在BGA附近 ...

模拟电子 音频数模转换器DAC抖动的灵敏度分析
Abstract: This application note describes how sampling clock jitter (time interval error or "TIE jitter") affectsthe performance of delta-sigma digital-to-analog converters (DACs). New insights explain the importanceof separately specifying low-frequency (< 2x passband frequency) and high-frequenc ...
