JAJSJT6A August 2020 – July 2021 TPS65994AD
PRODUCTION DATA
A Thunderbolt system is capable of sourcing USB, DisplayPort, and Thunderbolt data. There is an I2C connection between the TPS65994AD and the Thunderbolt controller. The TPS65994AD will determine the connection on the Type-C port and will generate an interrupt to the Thunderbolt controller to generate the appropriate data output. An external mux for SBU may be needed to mux the LSTX/RX and AUX_P/N signal from the Thunderbolt controller to the Type-C Connector. The TPD6S300 provides additional protection such as short to VBUS on the CC and SBU pins and ESD for the USB2 DN/P. See Figure 9-5 for a block diagram of the system.
