HX3 USB 3.0 Hub
General Description
HX3 is a family of USB 3.0 hub controllers compliant with the USB 3.0 specification revision 1.0. HX3 supports SuperSpeed (SS),
Hi-Speed (HS), Full-Speed (FS), and Low-Speed (LS) on all the ports. It has integrated termination, pull-up, and pull-down resistors,
and supports configuration options through pin-straps to reduce the overall BOM of the system.
HX3 includes the following Cypress-proprietary features:
Shared Link™: Enables extra downstream (DS) ports for on-board connections in embedded applications
Ghost Charge™: Enables charging of devices connected to the DS ports when no host is connected on the upstream (US) port
HX3 USB 3.0 Hub
Features
USB 3.0-Certified Hub, TID# 330000047
Supports up to Four USB 3.0-Compliant DS ports
All ports support SS (5 Gbps), and are backward-compatible
with HS (480 Mbps), FS (12 Mbps), and LS (1.5 Mbps)
SS and USB 2.0 Link Power Management (LPM)
Dedicated Hi-Speed Transaction Translators (Multi-TT)
LED status indicators – suspend, SS, and USB 2.0 operation
Shared Link™ for Embedded Applications
Each DS port can simultaneously connect to an embedded SS
device and a removable USB 2.0 device
Enables up to eight device connections
Enhanced Battery Charging
Each DS port complies with the USB Battery Charging v1.2
(BC v1.2) specification
Ghost Charge™: Each DS port can emulate a Dedicated
Charging Port (DCP) when the host is not connected to the US
port
Accessory Charger Adapter Dock (ACA-Dock): Enables
charging and simultaneous data transfer for a smart phone or
a tablet acting as a host compliant to BC v1.2
Apple charging supported on all DS ports
Integrated ARM® Cortex™-M0 CPU
16 KB RAM, 32 KB ROM

Architecture Overview
The Block Diagram on page 2 shows the HX3 architecture. HX3
consists of two independent hub controllers (SS and USB 2.0),
the Cortex-M0 CPU subsystem, an I2C interface, and port
controller blocks.
SS Hub Controller
This block supports the SS hub functionality based on the
USB 3.0 specification. The SS hub controller supports the
following:
SS link power management (U0, U1, U2, U3 states)
Full-duplex data transmission
USB 2.0 Hub Controller
This block supports the LS, FS, and HS hub functionalities. It
includes the repeater, frame timer, and four transaction trans-
lators.
The USB 2.0 hub controller block supports the following:
USB 2.0 link power management (L0, L1, L2, L3 states)
Suspend, resume, and remote wake-up signaling
Multi-TT (one TT for each DS port)
CPU
The ARM Cortex-M0 CPU subsystem is used for the following
functions:
System configuration and initialization
Battery charging control
Vendor-specific commands for the USB-to-I2C bridge
String-descriptor support
Suspend status indicator
Shared Link support in embedded systems
I2C Interface
The I2C interface in HX3 supports the following:
I2C Slave, Master, and Multi-master configurations
Configure HX3 by an external I2C master in I2C slave mode
Configure HX3 from an I2C EEPROM
Multi-master mode to share EEPROM with other I2C masters
In-System Programming of the I2C EEPROM from HX3’s
US port
Port Controller
The port controller block controls DS port power to comply with
the BC v1.2 and USB 3.0 specifications. This block also controls
the US port power in the ACA-Dock mode. Control signals for
external power switches are implemented within the chip. HX3
controls the external power switches at power-on to reduce
in-rush current.
The port controller block supports the following:
Overcurrent detection
SS and USB 2.0 port indicators for each DS port
Ganged and individual power control modes
Automatic port numbering based on active ports
Applications
Standalone hubs
PC and tablet motherboards
Docking station
Hand-held cradles
Monitors
Digital TVs
Set-top boxes
Printers
