All,

To address comments from the last Phy phone call, an update to “Proposed 6G SAS Phy Specs for EMI Reduction” has been posted as:

http://www.t10.org/ftp/t10/document.07/07-007r1.pdf, and

http://www.t10.org/ftp/t10/document.07/07-007r1.ppt

Now, both Class A and Class B FCC limits for radiated emission are shown.

Also, the complete formulas for single-ended to mixed mode s-parameter conversion are given.

Last, for those considering whether the proposed limit for SCD11 & SCD22 is realistic, the model now includes the effect of delay skew between the two dif’l inputs.  In addition to resistive and capacitive imbalance, this skew can have substantial effect on SCD11 & SCD22 at higher frequencies.  (In the Powerpoint version of the document, double-click on the chart to experiment with the parameters in an Excel workbook.)

Happy holidays,

Mike
