V6 GTX - pkpk differential swing value in PIPE spec does not match with corresponding value in the user guide


In (UG366), when the TXMARGIN is 100, the pkpk differential voltage swing is 100-200mv for full swing.

However in the PIPE specification the corresponding value is 200-400mv.

Why is the user guide different from the PIPE specification?


The value is vendor defined.

Set TXDIFFCTRL to 0010.

This will result in pkpk differential swing of 310 mV, which is inside the range of 200-400mv.
