电源纹波测量的 黄腾 大中华区业务和市场开发经理 十大注意事项 February 26, 2015 125MHz clock 讲座的目的 与您分享今天的技术成就，以便: – 更精确地调试和测试PDN (电源分布网络) – 更容易地隔离PDN 噪声的根本原因 – 避免错误的测试结果 – 了解让您工作变得更容易的特殊工具 从简单到高级，您今天需要留心的10件事情 7/7/2015 Page 2 Power Integrity Measurements Believe it or not, this is what a typical1.8V DC supply looks like if you The Need for Power Integrity zoom-in on the top of it. Measurements • Increased functionality, higher power density and higher frequency operation drives need for lower supply voltages • Power rail tolerances are much tighter (from +/- 5% down to +/- 1%) • Ripple, noise and transients riding on these lower DC supplies can adversely affect clocks and digital data 7/7/2015 Page 3 Power Integrity Measurements Common Power Integrity Measurements • Supply drift • PARD (Periodic and Random Disturbances)—noise, ripple and switching transients on power rails. • Static and dynamic load response. • Programmable power rail response. • High frequency transients and noise. • Product electrical validation at extended temperatures. 7/7/2015
