7.2.2 Detailed Design Procedure
Figure 7-2 shows an example implementation of an USB Type-C DRP port using TUSB542. Texas Instruments TUSB322 is shown here as channel configuration (CC) controller. Note: connections for CNFG pins of TUSB542 is an example only. The connection of the CNFG pins is application dependent; refer to Table 6-2, where the user can find the available settings.
It is recommended to run an overall system signal integrity analysis, to estimate the channel loss and configure the re-driver. It is also recommended to have pull-up and pull-down option on the configuration pins for debug and testing purposes.
The signal integrity analysis must determine the following:
- Equalization (EQ) setting
- De-emphasis (DE) setting
- Output swing amplitude (OS) setting
The equalization must be set based on the insertion loss in the pre-channel (channel before the TUSB542 device). The input voltage to the device is able to have a large range because of the receiver sensitivity and the available EQ settings.
The de-emphasis setting must be set based on the length and characteristics of the post channel (channel after the TUSB542 device).
