Topic: SAS-2 PHY WG 
Date: Thursday 
Time: 10:00 am, Central Standard Time 
Meeting number: 826 515 680 
Meeting password: 6gbpsSAS 
No call on 12/28. 
Agenda (more than we can cover): 
1. SAS-2 Electrical Specification Proposal 06-496 [Witt] 
http://www.t10.org/ftp/t10/document.06/06-496r2.pdf 
a. Concentrate on page 6: Transmitter device signal characteristics.
Avoid the de-emphasis line for this call and work on the more commonly 
agreed-upon numbers. 
b. De-emphasis measurement (page 8)
It seems that the major issue with the measurement technique is the window 
location that the measurements are made.
What if Vpk is the pk-pk voltage (wherever it is at) and Vde is a mode 
value? Since the test is made on the transmitter through a zero length 
load, the mode portion should not see too large of a spread.
c. Receiver Device Signal Characteristics (page 11)
2. 10-meter cable specification issues 
http://www.t10.org/ftp/t10/document.06/06-499r0.pdf 
Any updates? 
3. EMI considerations for SAS-2 
http://www.t10.org/ftp/t10/document.06/06-483r0.pdf 
Keep in mind when developing spec. 
4. Define a loss for the zero-length test load?
