ZHCSIY2B July 2018 – August 2021 TPS65988
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 TPS65988. Table 9-6 shows the TPS65988 GPIO events and the control signals from the TS3DS10224.
TPS65988 GPIO EVENT | TS3DS10224 CONTROL |
---|---|
Port 0 Cable Orientation Event | SAO, SBO |
Port 0 DP Mode Selection Event | ENA |
Port 0 TBT Event | ENB |
N/A | SAI tied to VCC |
N/A | SBI tied to GND |
Table 9-7 shows the connections for the AUX, LSTXRX, and SBU pins for the TS3DS10224.
