ZHCSLY5A August 2020 – July 2021 TPS65994AD
PRODUCTION DATA
The SBU signals must be muxed from the Type-C connector to the Thunderbolt controller. The AUX for DisplayPort and LSTX/RX for Thunderbolt are connected to the TS3DS10224 and then muxed to the SBU pins. The SBU mux is controlled through GPIOs from the TPS65994AD. Table 9-11 shows the TPS65994AD GPIO events and the control signals from the TS3DS10224.
| TPS65994AD GPIO EVENT | TS3DS10224 CONTROL |
|---|---|
| Cable_Orientation_Event_Port1 | SAO, SBO |
| DP_Mode_Selection_Event_Port1 | ENA |
| TBT_Mode_Selection_Event_Por1 | ENB |
| N/A | SAI tied to VCC |
| N/A | SBI tied to GND |
Table 9-12 shows the connections for the AUX, LSTXRX, and SBU pins for the TS3DS10224.
