The WarpLink device is clocked via the clock distribution networks originating from slot 7. (Please refer to the Clock Distribution section for
more details). The clock trigger of the TDS-8000 is also clocked with the same clock distribution network, by way of the Test Card in slot 1.

EYE DIAGRAMS FROM SLOT 8 TO SLOT 1
The interconnect between slots 8 and 1 are the longest channel in the 19" rack WarpLink Design Reference system that is not artificially
lengthened. The total length of the transmission channel in FR-4 is 18.7”. This includes 1.8” of FR-4 on the Line Card, 12.2” on the
backplane, and 4.7” on the Test Card. Without pre-emphasis/equalization, WarpLink exceeds the XAUI mask with a 5% margin. With pre-
emphasis/equalization, the WarpLink gigabit link satisfies the XAUI mask with a 9% margin. The comparison of Figure 17(a) and Figure
17(b) shows a clear benefit of pre-emphasis/equalization to the signal fidelity of the eye diagram.
EYE DIAGRAMS FROM SLOT 7 TO SLOT 1
The artificially lengthened interconnect between slots 7 and 1 presents a condition that is worse than that defined by the XAUI standard.
This is a worst case routing condition that exemplifies a routing implementation on a large backplane. The total length of the transmission
channel in FR-4 is 26.2”. This includes 1.8” of FR-4 on the Line Card, 19.7” on the backplane, and 4.7” on the Test Card. With pre-
emphasis/equalization on, WarpLink passes the XAUI mask with a 3% margin. As expected via simulation the resultant eye does not
conform to the XAUI mask with pre-emphasis/equalization disabled. Again, the comparison of Figure 18(a) and Figure 18(b) shows a clear
benefit of pre-emphasis/equalization to the signal fidelity of the eye diagram.
