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.
