ZHCSFF4C February 2016 – August 2021 TPS65981
PRODUCTION DATA
The Type-C port in this design supports DisplayPort and/or USB3.1 SuperSpeed data by adding the HD3SS460 multiplexer with GPIO input signals controlled by the TPS65981. Table 10-4 shows the DisplayPort configurations supported in the system. Table 10-5 shows the summary of the TPS65981 GPIO signals control for the HD3SS460. The HD3SS460 is also capable of multiplexing the required signals to the SBU_1/2 pins at the Type-C port.
DisplayPort Role | Display Port Pin Assignment | DisplayPort Lanes | |
---|---|---|---|
Configuration 1 | UFP_D | Pin Assignment C | 4-Lane |
Configuration 2 | UFP_D | Pin Assignment D | 2-Lane and USB 3.1 data |
