Hi Ti,
DS125DF1610 branch card.pdf
硬件通道如下：背板 <=> ds125df1610 <=> ds125mb203 <=> 面板10G/1G光模块。
可以通过i2c通道 ds125df1610和ds125mb203，进行配置。
问题：背板过来的信号，无论是1G信号, 还是10G的xfi信号，面板光口都不link（自环和对接其它设备，都不Link）.
ds125df1610芯片采用上电默认配置，ds125mb203采用的也是默认值，ds125mb203的寄存器如下：

疑问：
- ds125df1610芯片和ds125mb203，有没有透传模式或by-pass模式，因为目前不Link，我无法定位是ds125df1610芯片的问题，还是ds125mb203的问题？
- ds125df1610芯片的寄存器很多，对于背板过来的10G xfi信号，需要重点配置哪些寄存器？
- 目前ds125df1610芯片采用的是默认上电配置。之前，也手动配置过其它值，也不link。
- 也试过ds125mb203的pin mode，也不link。
- 麻烦提供一下：DS125DF1610和DS125MB203这2颗芯片的IBIS模型文件。
Kailyn Chen：
1. 这两个器件没有透传功能。
2. 关于这两个器件的link问题，我这边需要再看下。
3. 抱歉，这两个器件都没有提供IBIS model，但是可以在其产品主页上申请IBIS -AMI model：
