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 
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 
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 
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.
