特点

  • 使用符合 JEDEC 标准的通用 BGA 封装，为示波器提供探测 DDR4 DRAM x4/x8 封装的信号接入点
  • 周边焊接测试点可以与逻辑分析仪飞线或示波器焊接探针配合使用，拾取信号进行测试
  • 可以使用 InfiniiSim 波形转换软件扩展有效带宽
  • 从 DDR4 球到测试点的走线长度相匹配，可减少测量时序偏移
  • 与 InfiniiMax 探头兼容，包括 E2677A、N5381A 和 N5425A/N5426A 差分焊入式探头
  • 提供 S 参数模型，可以与 InfiniiSim 配合使用进行去嵌入

N2114A DDR4 BGA 内插器可拾取 DDR4 BGA 封装的时钟、选通、数据、地址和命令等信号，并使用 Infiniium 示波器进行电气和时序测量。 BGA 探头适配器符合 DRAM Ballout 定义的 DDR4 JEDEC 规范，使 BGA 封装可以直接拾取信号，实现真正的合规性测试。

N2114A DDR4 BGA 内插器可焊入到 DRAM 与印刷电路板或 DIMM 原卡之间，DRAM 通常焊接在此处。 内插器的下方是印刷电路板或 DIMM 封装，上方是 DRAM 封装。 来自存储器控制器芯片和 DRAM 的信号直接传输到 BGA 探头适配器的顶部，由示波器探头拾取这些信号进行探测。

Probing a Midpoint of a Transmission Line that is Not Load Terminated

Probing a Midpoint of a Transmission Line that is Not Load Terminated

With the advent of variable on die termination (i.e. ODT) many systems like low power double data rate memory (LPDDR) have the ability to either terminate a line in its characteristic impedance for high speed operation or terminate it with an open for lower speed operation. Many times there is a desire to probe the transmission line to monitor the signals on the line. When the transmission line is terminated in close to its characteristic impedance, the signals can be readily observed. However, if the line is terminated in an impedance that is not close to the characteristic impedance then it may not be possible to accurately measure the signals.
