Introduction
The TUSB7340 is a USB 3.0 xHCI 0.96 compliant host controller that supports up to four downstream
ports. The TUSB7320 supports up to two downstream ports. The TUSB73x0 interfaces to the host system
via a PCIe x1 Gen 2 interface and provides SuperSpeed, High-speed, Full-speed, or Low-speed
connections on the downstream USB ports.

EVM Board
1 TUSB7320 and TUSB7340 DEMO Boards
The TUSB7320 and TUSB7340 DEMO boards are both PCI Express X1 Standard Height cards. The
dimensions of both boards are 4.376 inches by 2.571 inches. The two figures below depict how the boards
look.

Hardware Setup

2 Hardware Setup
2.1 Headers
The EVM boards are populated with three headers: J22, J26, and J40.
J22 header is used to change the state of AUX_DET signal to the TUSB73XX. By default, this header is
not shorted and therefore AUX_DET will be high. If a jumper shunt is placed over J22, the AUX_DET will
be low.
The J26 header is used to route 5 V from the IDE Power Connector (J5) to the Texas Instruments
TPS2560 USB power switch. This header should always have a Jumper Shunt populated. For more
information on the Texas Instruments TPS2560, please visit www.ti.com.
J40 header is used to select the 3.3-V power source for the TUSB73X0. By default, a Jumper Shunt
should be populated across pins 1 and 2 of J40. When in this position, the 3.3-V power from the PCI
Express slot is routed to the TUSB73X0. If the Jumper Shunt is moved to pins 2 and 3, then the 3.3-V
VAUX power from the PCI Express slot is routed to the TUSB73X0. The Jumper Shunt should only be
moved to positions 2 and 3 if wake testing is required. Otherwise the jumper should be left in the default
position of 1 and 2.
NOTE: The 3.3-V VAUX power supply has a limited current capability. According to the PCI Express
Electromechanical Spec, the 3.3-V VAUX will have a maximum current of 375 mA. Because
of the limited current of 3.3-V VAUX, it is recommended to plug only one device into the
TUSB73X0. If the Jumper Shunt is left on pins 1 and 2 of J40, this current limitation does not
exist and therefore all ports of the TUSB73X0 can be used.
2.2 VBUS
VBUS for all of the USB ports comes from the IDE Power Connector (J5).
2.3 PCI Express Slot Options
Because the TUSB73X0 EVM boards are PCI Express X1, they can be used in any PCI Express Slot
(X1, X4, X8, or X16) on a typical motherboard. The boards can be used in either a PCI Express Gen1
(2.5 Gbps) or Gen2 (5 Gbps) slot. Because of the speed of USB3 (5 Gbps), if used in a PCI Express
Gen1 slot, the performance of the TUSB7320 or TUSB7340 will be negatively impacted. For this reason, it
is recommended to always insert the EVM board into a PCI Express Gen2 slot.

Bringup
Below are the steps to bring up the EVM board in a typical system:
1. Remove the power plug from the PC power supply.
2. Make sure the Jumper Shunts are populated on J26 and J40.
3. Insert the EVM board into a PCI Express slot. It is recommended to use a PCI Express Gen2 slot if
one is available.
4. Insert an IDE Power Connector into J5 of the EVM board.
5. Insert the power plug into the PC power supply.
6. Turn the PC on. Once the PC is turned on, all of the green LEDs should be ON. If LED D5 is not
active, please check to make sure the jumper shunt on J40 is populated. If none of the green LEDs
(D1 thru D4) for each USB Port are active, please check to make sure the Jumper Shunt on J26 is
populated and an IDE Power connector is plugged into J5.
7. Once the PC has booted into Windows 7, you will need to install the TI xHCI driver. If the driver has
already been installed on your PC, then you can proceed step 8. Otherwise, you will need to install the
xHCI driver by running the TI xHCI driver setup utility.
8. You can now insert devices into the USB ports.

WAKE Testing Setup
The EVM board can be used to test the WAKE functionality of the TUSB73X0. By default, the EVM is not
configured to support wake testing. Please configure the EVM according to the following if WAKE is
required:
1. Move the Jumper Shunt on J40 to pins 2 and 3.
2. Make sure there is no Jumper Shunt on J22.
3. Use a dedicated 5-V power supply for VBUS. Do NOT use the IDE Power connector provided from the
system power supply. The reason for not using the IDE power from system power supply is when the
system is put in a sleep or hibernate state, the power on the IDE Power connector will be turned off.
NOTE: For some motherboards, WAKE from a PCIe slot is not supported or is only supported on
PCIE X1 slots. Please make sure to use a motherboard that supports WAKE from any PCIe
slot.
