LS1043A, Serdes Query

[logeshs]

Hi,

In LS1043A, for SerDes where could i find TX TAP Controller Setting and Receiver DFE Control Settings?

Thanks.

Please explain where these parameters are mentioned and how do you plan to use these settings?

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.

Thanks

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.
