6.3.1 High-Speed Differential Signal Switching

Based on the data sent to the control pins, TMUXHS4446 provides the following muxing options:

  • USB SS only: connects only one group of TX & RX signals on the USB-C connector to a USB source/sink.
  • USB SS only (flipped): enables the USB SS only mode when the USB-C connector is flipped around.
  • 4 Ln DP: connects both groups of TX/RX signals on the USB-C connector to a DisplayPort source/sink.
  • 4 Ln DP (flipped): enables the 4 Ln DP mode when the USB-C connector is flipped around.
  • 2 Ln DP + USB SS: connects one group of TX/RX signals to a DisplayPort source/sink and connects the other group to a USB source/sink.
  • 2 Ln DP + USB SS (flipped): enables the 2 Ln DP + USB SS mode when the USB-C connector is flipped around.
  • Open (powered down): opens all switch and cuts of power to the device.
  • Open (powered on): opens all switches but keeps power to the device.
