Intel S10 dev kit p and n trace length matching on the board.

INTEL的Stratix10开发板上的光模块的收发信号并没有做等长处理，请问PCB线路是不需要做等长吗，收发器内部有能力处理线路不等长的设计吗？谢谢。

Hi,

As I understand it, you have some inquiries related to p and n trace length matching on the board. For your information, you should ensure matching length for the board trace for XCVR p/n pins. Sorry as I do not have insight into the design of the S10 devkit layout and could not further comment on that. However, you should ensure matching length on your board.

Thank you.
