Part Number:DS90UB948-Q1Other Parts Discussed in Thread:ALP,
Hi TI,
提供下ALP工具对DS90UB948-Q1进行Margin Analysis结果的判定标准,谢谢!
以上
Kailyn Chen:
您好,参考这篇应用手册,里面有详细介绍MAP如何判定,简单来说,具有至少三个均衡电平的裕度:包含一个passing状态连续的矩形,通过四个选通的位置测量两个EQ电平:
In general, TI recommends having a margin of at least three EQ levels with four passing strobe positions, including a contiguous rectangle of passing states that measures two EQ levels by four strobe positions.
参考FIgure 6 和FIgure 7的分析:https://www.ti.com/lit/an/snla301/snla301.pdf
