Component Population Configuration

To allow the TDP158 EVM to support both HDMI or DP input, there are many components that need to be
removed, placed, or modified depending on the board configuration.

Table 4

provides a summary of the

component configuration for the TDP158 RSB. In addition, the unused source receptacle can be
depopulated.
