3 Description
HD3SS3220 is a USB SuperSpeed (SS) 2:1 mux with
DRP port controller. The device provides Channel
Configuration (CC) logic and 5V VCONN sourcing
for ecosystems implementing USB Type-C. The
HD3SS3220 can be configured as a Downstream
Facing Port (DFP), Upstream Facing Port (UFP) or
a Dual Role Port (DRP) making it ideal for any
application.
The HD3SS3220, in DRP mode, alternates presenting
itself as a DFP or UFP according to the Type-C
specifications. The CC logic block monitors the CC1
and CC2 pins for pull-up or pull-down resistances to
determine when a USB port has been attached and
its port role. Once a USB port has been attached,
the CC logic also determines the orientation of the
cable and configures the USB SS mux accordingly.
Finally, CC logic advertises or detects Type-C current
mode – Default, Mid, or High in DFP and UFP modes
respectively.
Excellent dynamic characteristics of the integrated
mux allow switching with minimum attenuation to the
SS signal eye diagram and very little added jitter.
The device’s switch paths deploy adaptive common
mode voltage tracking resulting identical channel
despite different common mode voltage for RX and
TX channels.
