DS90UB948-Q1: Margin Analysis判定标准

Part Number: DS90UB948-Q1
Other 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

  • 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
