Feature Description
0x143 [7:2] RW Vertical height Taken together, the horizontal phase and
vertical height specify the Cartesian x-y
coordinates of the sample point on the eye
diagram. You can specify 64 heights on the
vertical axis.
0x145 [6:0] RW Horizontal phase Taken together, the horizontal phase and
vertical height specify the Cartesian x-y
coordinates of the sample point on the eye
diagram. You can increment through 128
phases over 2 UI on the horizontal axis. The
following encodings are defined:
• 7'h71 : Horizontal Phase 1
• 7'h70 : Horizontal Phase 2
• 7'h73 : Horizontal Phase 3
• 7'h72 : Horizontal Phase 4
• 7'h77 : Horizontal Phase 5
• 7'h76 : Horizontal Phase 6
• 7'h75 : Horizontal Phase 7
• 7'h74 : Horizontal Phase 8
• 7'h7D : Horizontal Phase 9
