7.2.2 USB-C Cross Point Mux with Signal Conditioner

The TDP2004-Q1 is a linear redriver with integrated cross-point mux. The device can be used to account for USB Type-C plug orientation as well as providing signal conditioing for DisplayPort mainlink signals. The TDP2004-Q1 can be used in both source and sink applications as illustrated in Figure 7-7. Using the SEL pin, typically driven by a USB PD controller in a system, the 4 channel signal paths can be configured as straight connection or cross connections as illustrated.

Note: The TDP2004-Q1 can only be used in USB-C applications where USB superspeed pins are used for DP alternate mode and USB3.x functionality is not required.
