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?
