Thanks John this is very helpful.

 

I think what it’s saying is the BLW, MPN, and Pmpn, and Rx degradation have different effects depending on whether the Transmitter has fast risetime and a lot of RIN, or Slow risetimes and less RIN.  The  BLW, MPN, and Pmpn are part of the “additional margin needed above TDP”.  We’d have to use the worst case for these.  The Rx degradation effect should be taken into account with the stressed receiver sensitivity test provided we create the worst case test.  (If the Rx degradation is larger then its sensitivity has be better to still pass stressed sensitivity.

 

Note this analysis doesn’t explain how VECP would create a more correlated result.  None of these effects would be in the VECP measurement.

Hello Jonathan & all

At the MMF ad hoc last week, there was a question regarding the cause of non-alignment between link model margin estimates and TDP margin estimates.  The attached page extracted from the presentation I prepared for the 802.3bm meeting speaks to that question.

Regards,

John

Dear all

As discussed at the last MMF ad hoc meeting, here are meeting details for the  MMF ad hoc call planned for Thursday 16^th January, 8am-10am (pacific).

The intent is to review some of the proposed responses to comments possibly needing discussion, to save some comment resolution time in Indiana Wells.

 I’ll select a short list and send out a provisional  agenda by Wednesday, and of course, suggestions are welcome.

Best wishes

jonathan
