USB Type-A Plug to USB Type-C Receptacle SuperSpeed MUX With DFP Controller Reference Design


Design files


The TIDA-00890 Dongle is designed to evaluate HD3SS3220 devices for DFP implementations.  This reference design can also be used as a hardware reference design for any implementation using the HD3SS3220 with a USB-C™ connector.  The layout files can be used as a guideline to implement the TUSB321A HD3SS3220 with illustrations of the routing/placement rules. The reference design includes on-board USB Type-A plug to connect to legacy USB systems. Please note that the design may include test components for evaluation purposes not applicable for production.

  • Operates off of the 5V VBUS from the legacy Type A USB connection
  • Can provide VCONN over a CC pin based upon Type C plug orientation and Ra detection
  • Has a USB Type-A plug and a USB Type-C™ receptacle.  The Type-A plug can be connected to a USB legacy Type-A receptacle for host side connection.
  • USB3 TX and RX signals are multiplexed through HD3SS3220 to support both connection orientations on the USB Type-C™ port. 
  • Small Design eases system implementation
