Texas Instruments  HD3SS3220RNHR

HD3SS3220 is a USB SuperSpeed (SS) 2:1 mux with DRP port controller. The device providesChannel Configuration (CC) logic and 5V VCONN sourcing for ecosystems implementing USB Type-C. TheHD3SS3220 can be configured as a Downstream Facing Port (DFP), Upstream Facing Port (UFP) or a DualRole Port (DRP) making it ideal for any application.

The HD3SS3220, in DRP mode, alternates presenting itself as a DFP or UFP according to theType-C specifications. The CC logic block monitors the CC1 and CC2 pins for pull-up or pull-downresistances to determine when a USB port has been attached and its port role. Once a USB port hasbeen attached, the CC logic also determines the orientation of the cable and configures the USB SSmux accordingly. Finally, CC logic advertises or detects Type-C current mode – Default, Mid, orHigh in DFP and UFP modes respectively.

Excellent dynamic characteristics of the integrated mux allow switching with minimumattenuation to the SS signal eye diagram and very little added jitter. The device’s switch pathsdeploy adaptive common mode voltage tracking resulting identical channel despite different commonmode voltage for RX and TX channels.
