请教一下使用Arria 10 transceiver去过采样155M的信号，需要注意什么事项。

Dear,

客户​使用Arria 10 transceiver去过采样155M的信号，CDR采样自动模式，发现CDR Lock to data经常会失去锁定。客户又希望使用CDR恢复时钟在PCS用户侧处理数据，请问该怎么设置PMA（CDR）？

​谢谢。

Hi Penn Tan,

This looks like duplicate case with another similar case that I responded to you.

Therefore, I am setting this case to closure so that we can stick to the other case for discussion.

Thanks
