["Upen Reddy Kareti (ureddy)" <00000d999961d690-dmarc-request@xxxxxxxxxxxxxxxxx>]

Hi All,

 

Two requests were made during my presentation today– here are my responses

1>  provide a link to my skew presentation – the following link is added to today’s presentation.

• Identifying basic skew profiles in freq. domain slide 13 of kareti_3dj_02_2401.pdf – actual step by step procedure how to  add skew is not shared

 

2> Max tap values for under 40 dB insertion Loss – separate stats for the ones passing COM of 3 dB and the ones not passing of 3 dB.

 

• note the following data is not as relevant once we start using COM code 4.6.3 as fixes are provided for tap location reporting issue.

• Also, when we configure with TX FFE and g_DC >0 setups.

 

For a case with post cursors of 8 fixed 3 banks (of 4 taps in each bank ) RX FFE span up to 100 UI and Package class B for both Transmitter and Receiver:

 

Channels < 40 dB and passing 3dB COM.

 

 

 

Channels < 40 dB and failing 3dB COM.

 

 

 

 

 

Regards

Upen
