Re: [802.3_50G] Jan 17 ad hoc - call for presentations

["Dudek, Mike" <Mike.Dudek@xxxxxxxxxx>]

Although there weren’t typo’s on page 5 I’m afraid there were typo’s and an omission from the proposed values on page 9.  Thanks to Nathan Tracy for pointing this out.

 

Page 9 should have said  (changes in Red).  I will be making these changes in a revised presentation that will be made at the Interim meeting.

 

 

 

•COM parameters

•RD=50 Ohms (was 55)

•Zcpackage = 95 Ohm

•Av/Afe= 0.415

•Ane=0.604

• Add an exception that Zc for the PCB = 100 Ohm (on page 236 line 39 change “parameter values given in Table 92-12” to “parameter values given in Table 92-12 except that Zc=100 Ohm”

•COM pass/fail criterion 3.3dB for Cable test, 3.0dB for interference calibration.

•TX specifications

•Add a sentence to 136.9.3.1.2 stating that Nv=13.

•Vf(min) = 0.354V

•SNRisi=31.2dB

•SNDR=32dB

During today’s ad hoc call there was a question as to whether there were some typo’s in my presentation in the Rlm row on page 5  and I took an action to provide an updated presentation if there was.   I confirm that the existing presentation is correct (the column ordering is not intuitive but the data is correct).
