Sideband Communication

Sideband communication is performed using a 3.3V low-voltage complementary metal-oxide semiconductor (LVCMOS)-level 1Mbps universal asynchronous universal transmitter (UART) comprising 10 bits: 1 start bit, 8 bits of data payload and 1 stop bit. Sideband transactions are transmitted over the SBTX pin and received from the SBRX pin and use the USB-C receptacle’s SBU1 and SBU2 pins. Sideband communication is used for these purposes:

  • Whether or not a port is connected (SBRX high > 25µs) or disconnected (SBRX low > 14µs).
  • To identify router manufacturer and product information.
  • To configure parameters of the USB4 link such as data rate (Gen2, Gen3, Gen4) and to enable or disable lanes.
  • Asymmetric support, initiation and decision.
  • Transmitter feed-forward equalization link-training handshake and whether or not routers are locked.
