Hi Team,
This mail with reference to previous ticket no.: CS0455461. Please respond to following quires at the earliest to release the board for fabrication.
Pullup and Pulldown on CLK and SGMII_SOP&N are implemented based on the reference board schematic from TI.
It is recommended to use for the CLK and SGMII_SO signals for Strap Configuration, so it is mandatory to have pullup and pulldown option.
Main concern is to ask why we need? Which specific configuration that is recommended? Is there any negative impact due to stubs and how to assess the impact and counter action to mitigate that?
As I requested in the previous mail we need SGMII Tx and Rx eye mask specification details for Signal Integrity analysis purpose. Kindly share the eye mask diagram and AC Timing Specifications.
- SGMII transmitter output compliance mask eye diagram and AC Timing Specifications.
- SGMII receiver input compliance mask eye diagram and AC Timing Specifications.
Attached schematic FYR.
Regard's
