DS280DF810: does the Pam4 diff+/diff- acceptable to swap ?

Hi Team,

My customer actually is designing the DS560DF810,

Duo to the layout convivence, customer would like to swap diff+/diff- in the design, does it acceptable ?

And  for retimer needs count correct data then get lock for internal CDR work correctly

If we change retimer input data, not sure retimer can work in correct stage?

Thanks!

Kai
