HX3 USB 3.0 Hub
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

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 I
2
C interface, and port
controller blocks.
I
2
C Interface
The I
2
C interface in HX3 supports the following:
■
SS Hub Controller
This block supports the SS hub functionality based on the
USB 3.0 specification. The SS hub controller supports the
following:
■
■
I
2
C Slave, Master, and Multi-master configurations
2
2
❐
Configure HX3 by an external I C master in I C slave mode
2
❐
Configure HX3 from an I C EEPROM
2
❐
Multi-master mode to share EEPROM with other I C masters
In-System Programming of the I
2
C 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:
■
■
■
■
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:
■
■
■
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
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)
