1.   Table 19 update (Brown)
     Excess differential input capacitance specification issue:
          Make reference to the time number instead of capacitance and
     update note f.
          1.5 Gbps 150 ps max
          3.0 Gbps 100 ps max

     02-210r2 was recommended to T10 for inclusion in SAS, 7 YES / 0 NO / 3

2.    Test load (Jenkins)
      Review proposal T10 document 02-240r0

     Significant discussion on this item. Mike Jenkins will update the
     drawing to specify 1.5 and 3.0 GHz and scale the numbers accordingly.
     Decided to use the same equation and thus the same test vehicle as
     XAUI. Mentioned that the sample in the figure was worse than 4dB.  It
     is not certain whether the values match the near end and far end
     values specified in the existing SAS tables. Mike to update so that
     the topic can be reviewed during the T10 meeting next week. Since Mike
     will not be present, a teleconference has been scheduled for this
     topic on 7/22 (see below).

3a.    OOB speed negotiation
      Review proposal T10 document 02-198r4

     See item 3b. Additional review during face-to-face.

3b.    Loop Lock time (Brown)
      New item. Need information posted.

     Information was posted to the reflector and discussed during the call.
     Determined to be part of the OOB speed negotiation topic. IC suppliers
     concerned about lock time allowances during speed negotiation. FCAL
     allows approximately 500us and would be beneficial for design latitude
     in SAS, especially since speed negotiation is not often performed.
     Recommended that the protocol group consider the FCAL timing for the
     RCD interval.

4.    Jitter tolerance compliance points table review (Jenkins/Kramer)
      Status of review.

     Jenkins and Kramer to review and Kramer will present durig

5.    Common Mode Shift Oxide Stress (Cable)
      Review proposal T10 document 02-247r0

     Not covered. Review during face-to-face.

6.   3.3V LED driver characteristics

     Not covered. Review during face-to-face.
