We are planning to run XFI in Backplane. Although XFI is not meant for Backplane, there is no clear indication in RM (or) Datasheet whether LS1043A supports any other interface (like 10Gbase-KR). So, we want to know where we can control Pre-emphasis, de-emphasis settings.
All adjustable lane paramers are documented in the processor's RM, Chapter 32 SerDes Module.
Please note that robust XFI operation as backplane without retimers is not guaranteed because of very high signal losses.
