HX3 USB 3.0 HUB REFERENCE DESIGN KIT (RDK)
CY4609 QUICK START GUIDE
Step 1: Conguring the HX3 Board
• Unpack the kit contents which includes RDK board, 5-V 4-A
AC-DC adapter and the USB 3.0 A to micro-B cable
• Ensure that the conguration mode select jumpers (J6
and J7)
are set for default operation, as shown above
Step 2: Powering the HX3 Board
• Plug the AC-DC adapter into an AC wall power receptacle.
Connect the power supply plug to the board’s DC supply
jack. The power LED (PWR) glows green to indicate that
the board is powered and the suspend status LED (SUSP)
glows amber to indicate that the hub is in suspend mode

Step 3: Connecting the HX3 Board to a USB 3.0 PC / Laptop
• Connect the micro-B end of the USB cable to the
board’s
upstream port; connect the other end to the USB 3.0
receptacle on a PC / laptop. The SUSP LED* turns off
(on a PC / laptop running Windows 7 operating system)
Step 4: Demonstrating USB 3.0 Data Transfer
• Get a USB 3.0 certied ash drive and store a 2 GB le.
Connect the ash drive to one of the downstream ports
• Copy the 2 GB le from the ash drive to the PC / laptop
to transfer data in USB 3.0 mode
Step 5: Demonstrating Battery Charging
•Connect an Apple device or an USB battery charging
device to any of the downstream ports. The HX3 board
will charge the connected device
Note: When the Ghost Charging feature is enabled, charging
of the device stops momentarily and resumes in 1-2 seconds
Step 6: Demonstrating Ghost ChargingTM
• Disconnect the USB cable from the upstream port to detach
the board from the PC / laptop. The device connected to
the downstream port continues to be charged using the
Ghost ChargingTM feature

HX3 USB 3.0 HUB REFERENCE DESIGN KIT (RDK)
Kit Operation: CY4609 is the reference design kit for CYUSB3304-68LTXC, a 4-port USB 3.0 hub controller from
Cypress. The hub controller supports Low-Speed (LS), Full-Speed (FS), Hi-Speed (HS) and SuperSpeed (SS) peripherals
on all the four downstream ports. It goes into Suspend state to save power when the upstream port is not connected to
a PC / laptop. All the downstream ports are compliant to USB Battery Charging Specication v1.2; they also emulate
Apple charging. The hub controller also supports Ghost Charging, a unique feature where the downstream ports
emulate Dedicated Charging Port (DCP) to support battery charging even when the upstream port of the board is not
connected to a PC / laptop.
The hub controller can be congured for parameters such as vendor ID, product ID, etc. using a Windows based PC
tool named Blaster Plus. The congured values are stored in an on-board EEPROM. This tool also can be used to
download the latest HX3 rmware to the on-board EEPROM. To access the Blaster Plus tool, the kit user guide, and
the hardware design les, download the RDK EXE le (CY4609HX3RDKSetup.exe) from www.cypress.com/CY4609.
Click the EXE le and follow the steps in the installer window.
