TDP2004 Evaluation Module
Description
The TDP2004 EVM is a PCB created to help
for customers evaluate the TDP2004 for video
applications with Display Port (DP) interfaces. This
EVM can also be used as a hardware reference
design for implementations of the TDP2004. PCB
design or layout files can be provided upon request
to provide PCB design illustrations of the routing or
placement rules with a TDP2004 component.
