11.2 Layout Example

Figure 21. Layout Example

Figure 22 demonstrates the solution of mismatched order between the output of the device and the DisplayPort connector for the source using BGA package. Top image of Figure 22 shows the crossing section between TDP142 and connector. Usually, Vias would be applied to avoid the cross, but using Via can attenuate the signal integrity. Therefore, the polarity swap would be implemented at the input of TDP142. The bottom image shows there is no more crossing section between the TDP142 and connector, which can minimize the number of Vias being used. Note that, the solution is only useful for the source using BGA package.
