The dial in number has changed for this and future calls. Please use the new number as the old one will not place you in the call. Toll Free Dial in Number: (877)810-9442 International Access/Caller Paid Dial In Number: (636)651-3190 PARTICIPANT CODE: 3243413 Webex information: https://seagate.webex.com/seagate Topic: SAS-2 PHY WG Date: Thursday Time: 10:00 am, Central Daylight Time (GMT -05:00, Chicago) Meeting number: 826 515 680 Meeting password: 6gbpsSAS Agenda: Status on Face-to-face tasks: Kevin Witt to provide an initial draft of the reference receiver description. Items include The reference receiver has a 2 tap DFE with infinite precision taps and unit interval tap spacing. The reference coefficient adaptation algorithm is the Least Mean Squared (LMS). The receiver’s return loss is illustrated in Figure xyx. Equalized inner eye mask. (100mV vertical and .6 UI horizontal after equalization) Bounds on tap weights (magnitude, time, sign) Channel specification (reference transmitter and reference receiver plus simulation). Need to complete the reference receiver and transmitter specifications and then make a description of how to evaluate the channel based on the reference receiver, reference transmitter, and s-parameter measurement of a channel plugged into a generic analysis tool such as StatEye. Harvey may provide a short draft of this methodology. Also reference the update to 5.3.3 in 07-063r5. Harvey was asked to provide access to a SAS-loaded example in version 4 of StatEye that has the reference transmitter, reference receiver, and reference channel parameters already loaded to aid users in faster simulations by allowing them to just change parameters as required for their particular set of objects rather than having to load the details of every item. Mike Jenkins to provide values for the reference transmitter return loss table. Physical TCTF [Bari] Mabubal to update the proposal started be Adrian. This proposal needs an update to include statistical confidence levels of test results. Continue discussion of 07-063. Revision 5 has been posted. It includes added text to 5.3.3 and updates of Table 52 and Table 60. Table 60 needs particular attention as the jitter tolerance notes are based on TJ and DJ while the new electrical table has TJ and RJ. Need to continue the jitter discussion. ST will post the information on the jitter transfer function prior to next week's call so we can discuss it then. http://www.t10.org/ftp/t10/document.07/07-063r5.pdf Alvin Cox Seagate Technology, LLC Tel 405-350-7424 Cell 405-206-4809 E-Mail alvin.cox@seagate.com
