SiI 1162 PanelLink Transmitter
Data Sheet
In addition to following the trace routing recommendations, length differences between intra-pair traces listed in
column 2 of Table 5 and inter-pair traces listed in column 3 of Table 5, should be controlled to minimize DVI skew.
Spacing between inter-pair DVI traces should be observed to reduce trace-to-trace couplings. For example,
having wider gaps between inter-pair DVI traces will minimize noise coupling. It is also strongly advised that
ground not be placed adjacent to the DVI traces on the same layer. Table 5 lists the recommended limits for the
parameters listed above.
The layout in Figure 26 illustrates an optimized AGP ADD Card with source termination, input termination
resistors and DVI connector mapping which follows the guidelines listed above. The trace length from the SiI
1162 to the DVI connector can be long; however, it is strongly recommended that the intra-pair and inter-pair
trace lengths follow the guidelines listed in Table 5.
