Introduction
The TI TUSB8040A evaluation module is a functional board design of a single device that implements
both a USB 3.0 hub and a USB 2.0 hub. The EVM can support both SuperSpeed (SS) and USB 2.0 (HS,
FS, and LS) operation on its USB ports. This EVM is intended for use in evaluating system compatibility,
developing optional EEPROM firmware, and validating interoperability. This EVM also acts as a hardware
reference design for any implementation of the TUSB8040A.
Upon request, layout files for the EVM can be provided to illustrate techniques used to route the
differential pairs, use of split power planes, placement of filters and other critical components, and
methods used to achieve length matching of critical signals.
A Note the EVM dimensions of 3” x 4” accommodates various lab test components, actual production implementations
can be much smaller. Also, the TUSB8040AEVM is laid out to accept either a TUSB8040A unit or a socket. This
socket functionality would not need to be duplicated on a production implementation.

Hardware Overview
The TUSB8040AEVM board hardware can be divided into five functional areas:
1 TUSB8040A
The TUSB8040A on the TUSB8040AEVM (U1 on the schematic) operates as a functional interconnect
between an upstream connection to a USB host or hub and up to four directly connected downstream
devices or hubs. More devices and hubs can be supported if arranged in tiers. The TUSB8040A is
capable of supporting operation at USB SuperSpeed (SS), High-Speed (HS), Full Speed (FS) or Low
Speed (LS). In general, the speed of the upstream connection of the TUSB8040AEVM limits the
downstream connections to that speed (SS, HS, and FS) or lower.
The TUSB8040A requires a 24-MHz low ESR crystal, Y1 with a 1-MΩfeedback resistor. The crystal
should be fundamental mode with a load capacitance of 12 pF – 24 pF and a frequency stability rating of
±100 PPM or better. To ensure a proper startup oscillation condition, a maximum crystal equivalent series
resistance (ESR) of 50 Ωis recommended.
The TUSB8040A can also use an oscillator or other clock source. When using an external clock source
such as an oscillator, the reference clock should have ±100 PPM (or better) frequency stability and have
less than 50-ps absolute peak to peak jitter (or less) than 25-ps peak to peak jitter after applying the USB
3.0 jitter transfer function.
2 USB Port Connectors
The TUSB8040AEVM is equipped with 5 standard nine pin USB 3.0 port connectors. One of these five
connectors, J1, is a Type B connector designed to interface with an upstream USB host or hub. The
remaining connectors, J2-J5, are Type A connectors for connection to downstream devices or hubs.
Standard size connectors were used on the EVM design, but USB micro connectors can be used if
desired. It is also possible to implement a legacy USB connector on one or more of the downstream ports
if SuperSpeed operation is not desired.
The USB ports can be attached via a standard USB cable to any USB 3.0 or legacy USB host, hub or
device. The TUSB8040A will automatically connect to any upstream USB 3.0 host or hub at both
SuperSpeed and High-Speed. Using a legacy USB cable between the TUSB8040AEVM and a USB 3.0
host or hub will force it to High-Speed operation. The same is true if a legacy USB cable is used between
the TUSB8040A EVMand a downstream SuperSpeed capable device in that operation will be limited to
USB High-Speed.
2.1 USB Port Connector - Power
VBUS is received from the upstream host or hub on J1. The TUSB8040A is configured as a self-powered
hub, so there should not be any significant current draw by the EVM from VBUS. The TUSB8040A does
monitor the VBUS input after filtering through a resistor divider network of a 90.9-kΩ, 1% resistor, R1, and
a 10-kΩ, 1% resistor, R3. VBUS cannot be directly connected to the TUSB8040A device.
NOTE: The VBUS LED implemented on the EVM will cause a USB 2.0 compliance issue because it
draws greater than 2-mA of current while the USB connection is suspended. It is included for
lab evaluation purposes only.
A bulk capacitor of at least 1 µF is required on the upstream port VBUS input to comply with the USB
specification. The TUSB8040AEVM uses a 10-µF capacitor, C37.

www.ti.com Hub Configuration
VBUS, sourced by the 5-V wall power input, J6, is provided to the downstream port connectors so that bus
powered devices may be attached to the downstream ports. The USB 3.0 specification limits the current
consumption of a USB 3.0 device to 900 mA at 5 V. The current limiting parameter of the TPS2560
devices, U19 and U21, is configured to 1.5 A to avoid any spurious over-current events due to bus-
powered HDD spin-up power fluctuations (SLVS930). A production implementation could place stricter
limits on this power consumption. An over-current event on any of the downstream port connectors will be
reported to the TUSB8040A via the OVERCURxZ inputs.
2.2 USB Port Connector – Noise Filtering
Each downstream VBUS output has a 150-µF bulk capacitor (C65, C67, C72, C75) as recommended by
the TPS2560 data manual to prevent in-rush current events on the downstream devices. In addition, there
are ferrite beads and small capacitors on the VBUS lines to reduce noise and address ESD/EMI concerns.
The TUSB8040AEVM also implements optional isolation using two small noise filtering capacitors and a
1-MΩresistor between the earth ground of each connector and the digital ground of the EVM, this is not a
requirement but should be used if ground isolation is desired.
Please note that the series capacitors implemented on the SS TX pairs are incorporated to satisfy the
USB 3.0 requirement that differential links be AC coupled on the transmit pair.
3 Hub Configuration
The TUSB8040AEVM can be configured by setting several inputs to the TUSB8040A that are sampled at
power-on reset or using an optional serial EEPROM. See section 3.1 for a full description of these inputs
and how to configure them. A production implementation would either rely on the default internal pull-up or
pull-down resistor for each configuration input or over-ride it with an external pull-up or pull-down resistor.
4 Optional Serial EEPROM
Each TUSB8040AEVM is equipped with an onboard EEPROM/socket placeholder. A small I2C EEPROM
can be installed to set the configuration registers as defined in the TUSB8040A data manual (SLLSEA7).
In its default setting, the EVM does not have an EEPROM installed and instead uses the configuration
inputs to determine any optional settings of the TUSB8040A.
The EEPROM interface defaults to programmable (not write-protected) so that any installed EEPROM’s
contents may be modified to test various settings. If an EEPROM data change is required, the values may
be changed using the register access methods outlined in the TUSB8040A data sheet (SLLSE97). In
addition, a Windows®based EEPROM utility is available upon request.
5 Power/Reset
The TUSB8040AEVM operates from the power provided by a 5-V wall power adapter, not bus power
supplied by a USB host. It is recommended to use a wall power adapter that is capable of sourcing 4 A to
5 A because the hub must be able to source significant power on its downstream ports (900 mA per port).
The TUSB8040AEVM uses a single channel LDO voltage regulator to drop 5 V to 3.3 V. The TPS7A4533,
U20, is a 1.5-A output linear regulator (SLVS720). The 1.1-V core voltage required by the TUSB8040A is
sourced by the 3.3-V rail to reduce unnecessary heat dissipation. The TPS74801, U22, is a 1.5-A output
single channel LDO linear regulator (SBVS074). Both regulators require few external passive components
and are appropriately rated for heat dissipation.
While there are two power-on reset sources on the TUSB8040AEVM, only one is required. Implemented
on the EVM is a supervisory circuit, TPS3808G33, U2 (SBVS050). This device has two input sources: the
BOARD_3P3V power rail and the 1.1-V regulator power good output. The other reset source is the RC
circuit created by the internal pull-up resistor of GRSTz and the 1-µF capacitor, C18. If R4-R7, C16 and
C17 are installed, the reset supervisor circuit is enabled. If those passive components are not populated,
the RC circuit is enabled.
The TUSB8040A requires a power on reset of 3 ms, the value of the capacitor used in the RC circuit
would vary based on the voltage ramp characteristics of the implementation.

Optional Circuitry www.ti.com
6 Optional Circuitry
The TUSB8040AEVM design implements a variety of LEDs, none of which are required by the USB
specification. They are provided to make testing and debug easier.
• D1 – Indicates that the upstream USB port is connected at High-Speed.
• D2 – Indicates that the upstream USB port is connected at SuperSpeed.
• D3 – Indicates that the upstream USB port has entered a High-Speed suspend state.
• D4 - Indicates that the upstream USB port has entered a SuperSpeed suspend state.
• D5 – Indicates when VBUS is provided to the upstream USB port.
• D6 – Indicates that 5 V is being applied to the TUSB8040AEVM.
• D7, D8, D10, D11 – Indicate when VBUS is applied to the downstream USB ports. The
TUSB8040AEVM enables or disables power to all downstream USB ports simultaneously.
• D9 – Indicates BOARD_3P3V is active
• D12 – D15 (dual LEDs) – Implement the USB 2.0 specification for port indicator LEDs. These LEDs
indicate if the downstream ports are connected at USB 2.0 speeds (green) or if there is an over current
event on a downstream port (amber).
The TUSB8040AEVM incorporates ESD protection circuitry for the differential pairs of all five ports. The
TPD2EUSB30 devices are not required or populated on the EVMs, but are recommended for any system
where ESD events are a concern, especially if the end equipment requirements exceed the device
specifications (i.e. HBM 2000 kV, CDM 500 V) (SLVSAC2).
The switches present on the TUSB8040AEVM are intended for TI lab evaluation only and are not required
for production designs.

Hardware Set Up
1 Configuration Switches
The TI TUSB8040AEVM has two sets of switches to facilitate configuration changes. Changing these
switch settings without a complete understanding of the result is not recommended. Configuration inputs
are only read by the TUSB8040A during power on reset, changing the switch settings while the EVM is
powered on will have no effect. Please refer to the EVM schematic for additional information (included in
the appendix).
Figure 2. Configuration Switches
The switch definitions are as follows, with the standard setting in parenthesis:
SW1_1 (on): FULLPWRz Switch. The TUSB8040A has an internal pull up on this terminal, so the
TUSB8040A defaults to a non full power management mode. If the switch is set to the ON position, the
terminal is pulled low and full power management mode is enabled. This means that the TUSB8040A
reports that it supports downstream port power switching in the USB descriptors it sends to the USB host.
Since the TUSB8040AEVM does implement downstream port power switching, full power management
mode should be enabled.
SW1_2 (off): SMBUSz Switch. The TUSB8040A has an internal pull up on this terminal, so I2C interface
mode is enabled by default. If the switch is set to the ON position, the terminal is pulled low and SMBUS
mode is enabled.

Configuration Switches www.ti.com
SW1_3 (off): SCL (Serial Clock) Switch. The TUSB8040A has an internal pull down on this terminal, so
the serial EEPROM/SMBUS interface is disabled. If the switch is set to the ON position, a pull up resistor
is connected to the serial clock terminal to indicate that an I2C EEPROM may be attached (along with a
pull up resistor on SDA).
The SCL_SMBCLK terminal is also sampled at the deassertion of reset to determine if USB 3.0
SuperSpeed low power states U1 and U2 initiation is disabled. If SCL_SMBCLK is high, U1 and U2 low
power state initiation is disabled. If SCL_SMBCLK is low, U1 and U2 low power states are completely
enabled. If the optional EEPROM or SMBUS is implemented, the value of the u1u2TimerOvr bit of the
Device Configuration Register determines if the low power state initiation is enabled.
SW1_4 (off): SDA (Serial Data) Switch. The TUSB8040A has an internal pull down on this terminal, so
the serial EEPROM/SMBUS interface is disabled. If the switch is set to the ON position, a pull up resistor
is connected to the serial clock terminal to indicate that an I2C EEPROM may be attached (along with a
pull up resistor on SCL).
The SDA_SMBDAT terminal is also sampled at the deassertion of reset to determine if the USB 3.0
SuperSpeed low power states U1 and U2 are disabled. If SDA_SMBDAT is high, U1 and U2 low power
states are completely disabled. If SDA_SMBDAT is low, U1 and U2 low power states are enabled. If the
optional EEPROM or SMBUS is implemented, the value of the u1u2Disable bit of the Device Configuration
Register determines if the low power state U1 and U2 are enabled. Note that disabling U1 and U2 via the
SDA_SMBDAT terminal, overrides the U1 and U2 initiation disable of the SCL_SMBCLK terminal.
SW1_5 (off): PWRz_BAT1 Switch. The TUSB8040A has an internal pull down on this terminal, so USB
Battery Charging mode on Port 1 is disabled by default. If the switch is set to the ON position, the terminal
is pulled high and battery charging is enabled on downstream port 1.
SW1_6 (off): PWRz_BAT2 Switch. The TUSB8040A has an internal pull down on this terminal, so USB
Battery Charging mode on Port 2 is disabled by default. If the switch is set to the ON position, the terminal
is pulled high and battery charging is enabled on downstream port 2.
SW1_7 (off): PWRz_BAT3 Switch. The TUSB8040A has an internal pull down on this terminal, so USB
Battery Charging mode on Port 3 is disabled by default. If the switch is set to the ON position, the terminal
is pulled high and battery charging is enabled on downstream port 3.
SW1_8 (off): PWRz_BAT4 Switch. The TUSB8040A has an internal pull down on this terminal, so USB
Battery Charging mode on Port 4 is disabled by default. If the switch is set to the ON position, the terminal
is pulled high and battery charging is enabled on downstream port 4.
SW2_1 (off): USED1 Switch. The TUSB8040A has an internal pull up on this terminal, so Port 1 is
enabled by default. If the switch is set to the ON position, the terminal is pulled low, Port 1 is disabled and
the TUSB8040A will report as 3 port hub (or less if other USEDx terminals are set low).
SW2_2 (off): USED2 Switch. The TUSB8040A has an internal pull up on this terminal, so Port 2 is
enabled by default. If the switch is set to the ON position, the terminal is pulled low, Port 2 is disabled and
the TUSB8040A will report as 3 port hub (or less if other USEDx terminals are set low).
SW2_3 (off): USED3 Switch. The TUSB8040A has an internal pull up on this terminal, so Port 3 is
enabled by default. If the switch is set to the ON position, the terminal is pulled low, Port 3 is disabled and
the TUSB8040A will report as 3 port hub (or less if other USEDx terminals are set low).
SW2_4 (off): USED4 Switch. The TUSB8040A has an internal pull up on this terminal, so Port 4 is
enabled by default. If the switch is set to the ON position, the terminal is pulled low, Port 4 is disabled and
the TUSB8040A will report as 3 port hub (or less if other USEDx terminals are set low).
SW2_5 (off): RMBL1 Switch. The TUSB8040A has an internal pull up on this terminal, so any devices
connected to Port 1 are reported as removable by default. If the switch is set to the ON position, the
terminal is pulled low and the TUSB8040A will report a device connected to Port 1 as non-removable.
SW2_6 (off): RMBL2 Switch. The TUSB8040A has an internal pull up on this terminal, so any devices
connected to Port 2 are reported as removable by default. If the switch is set to the ON position, the
terminal is pulled low and the TUSB8040A will report a device connected to Port 2 as non-removable.
SW2_7 (off): RMBL3 Switch. The TUSB8040A has an internal pull up on this terminal, so any devices
connected to Port 3 are reported as removable by default. If the switch is set to the ON position, the
terminal is pulled low and the TUSB8040A will report a device connected to Port 3 as non-removable.

SW2_8 (off): RMBL4 Switch. The TUSB8040A has an internal pull up on this terminal, so any devices
connected to Port 4 are reported as removable by default. If the switch is set to the ON position, the
terminal is pulled low and the TUSB8040A will report a device connected to Port 4 as non-removable.
2 Hardwired Configurations
PORTINDz - The TUSB8040A has an internal pull up on this terminal, so port indicator LED support is not
reported to the USB host by default. Since the TUSB8040AEVM has port indicator LEDs, this terminal has
been pulled low.
GANGED - The TUSB8040A has an internal pull up on this terminal, so ganged downstream power switch
support is reported to the USB host by default. Since the TUSB8040AEVM has individual downstream port
power switches, this terminal has been pulled low.
HS_SUSPEND_POLARITY - The TUSB8040A samples HS_SUSPEND_POLARITY at the deassertion of
reset to determine the polarity of the downstream port power switch enables. The TUSB8040A has an
internal pull down on this terminal to set the power enables to active low. Since the TUSB8040AEVM
implements power switches with active low enables, R97 is not populated.
SS_SUSPEND_SSC - The TUSB8040A samples SS_SUSPEND_SSC at the deassertion of reset to
determine if SSC is enabled. The TUSB8040A has an internal pull down on this terminal to enable SSC.
Since several devices and hosts in the USB 3.0 community have SSC locking issues, SSC is disabled on
the TUSB8040AEVM and R98 is populated.
3 SMBUS Support
The TUSB8040AEVM must be modified to support the SMBUS option:
SMBUSz (switch 1_2) must be set to the ON position.
SCL_SMBCLK (switch 1_3) must be set to the ON position to enable the pull-up.
SDS_SMBDAT (switch 1_4) must be set to the ON position to enable the pull-up.
SMBUS Address: 0x40:
FULLPWRMGMNTz_SMBA1– low on TUSB8040AEVM
GANGED_SMBA2 – low on TUSB8040AEVM
PORTINDz_SMBA3– low on TUSB8040AEVM
SMBUS Address: 0x41:
FULLPWRMGMNTz_SMBA1 (switch 1_1)– high on TUSB8040AEVM
GANGED_SMBA2 – low on TUSB8040AEVM
PORTINDz_SMBA3– low on TUSB8040AEVM
External connections to SDA_SMBDAT and SCL_SMBCLK can be made at the I2C EEPROM footprint.
4 EVM Installation
To install the EVM, perform the following steps:
1. Attach a 5-V wall power source to J6. LEDs D6 and D9 should be lit.
2. Attach a USB cable between J1 and a USB host. LEDs D5, D7, D8, D10 and D11 should be lit.
(a) If the TUSB8040AEVM is attached to a USB 3.0 host, D1 and D2 should be lit.
(b) If the TUSB8040AEVM is attached to a USB 2.0 host, D1 should be lit.

Case 1: Device function(s) are “banged out” in Device Manager.
• Make sure that the latest updates are installed for the operating system.
• Make sure that the latest drivers are installed for the host controller.
Case 2: The EVM does not work at all.
• Verify that all switches are in their default state and the EVM is powered on with a 5-V source with
adequate current.
• If installed, remove the serial EEPROM from the EEPROM socket. The EVM does not require an
EEPROM to operate.
• In the case where a 12-V power supply has been attached to the EVM, the fault is non-recoverable.

TI recommends using a R82 with a value of
2.49K to counter the IR drop of the ferrite bead,
FB2. If a ferrite bead with very low DC resistance
is used, R82 should be populated with a 1.87K
resistor.

Concerning EVMs including radio transmitters
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this
device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired
operation of the device.
Concerning EVMs including detachable antennas
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain
approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should
be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
This radio transmitter has been approved by Industry Canada to operate with the antenna types listed in the user guide with the maximum
permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain
greater than the maximum gain indicated for that type, are strictly prohibited for use with this device.
Cet appareil numérique de la classe A ou B est conforme à la norme NMB-003 du Canada.
Les changements ou les modifications pas expressément approuvés par la partie responsable de la conformité ont pu vider l’autorité de
l'utilisateur pour actionner l'équipement.
Concernant les EVMs avec appareils radio
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est
autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout
brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement.
Concernant les EVMs avec antennes détachables
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain
maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à
l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente
(p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante.
Le présent émetteur radio a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés dans le manuel
