7.2.1.2 Detailed Design Procedure

The TDP2004 provides signal conditioning for four DP mainlink channels. The device is a linear redriver which is agnostic to DP link training. The DP link training negotiation between a display source and sink stays effective through the device. The redriver becomes part of the electrical channel along with passive traces, cables, and other channel elements, resulting in optimum source and sink parameters for best electrical link. Figure 7-2 shows a simplified schematic for DisplayPort application using TDP2004.

DisplayPort side band signals AUXp,n and HPD is bypassed. The link will still have successful link training through TDP2004. An inverted HPD signal can be used to control the device standby operation utilizing the PD pin; however appropriate filtering out of HPD interrupt signals must be provisioned.

In some applications where a micro-controller or other link monitoring device has DP link state information, it can exercise I2C registers of TDP2004 for additional power management.
