Data Sheet
In addition to following the trace routing recommendations, length differences between intra-pair traces listed in
column 2 of Table 11 and inter-pair traces listed in column 3 of Table 11, 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 11 lists the recommended limits for the
parameters listed above.
