Overview
The HD3SS3220IRNHT is a USB SuperSpeed (SS) 2:1 multiplexer (mux) with a Dual Role Port (DRP) controller, designed by Texas Instruments. This device is tailored for ecosystems implementing USB Type-C and supports USB 3.1 Gen 1 and Gen 2 speeds up to 10 Gbps. It provides Channel Configuration (CC) logic and 5V VCONN sourcing, making it versatile for various USB Type-C applications.
The HD3SS3220IRNHT can be configured as a Downstream Facing Port (DFP), Upstream Facing Port (UFP), or a Dual Role Port (DRP), allowing it to adapt to different roles according to the Type-C specifications. The CC logic block monitors the CC1 and CC2 pins to determine the attachment and orientation of the USB port, and it configures the USB SS mux accordingly.
