TUSB8041RGC REVD Evaluation Module
The Texas Instruments TUSB8041RGC REVD evaluation module (EVM) 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 TUSB8041.

Introduction
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.
NOTE: The EVM accommodates various lab test components; actual production implementations
can be much smaller.

Hardware Overview
The TUSB8041 EVM board hardware can be divided into the following functional areas:
2.1
TUSB8041RGC
The TUSB8041 on the TUSB8041 EVM (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 TUSB8041 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 TUSB8041 EVM limits the downstream connections
to that speed (SS, HS, and FS), or lower.

Hardware Overview
www.ti.com
The TUSB8041 requires a 24-MHz low-ESR crystal, Y1, with a 1-MΩ feedback resistor. The crystal should
be fundamental mode with a load capacitance of 12 to 24 pF and a frequency stability rating of ±100 PPM
or better. To ensure a proper startup oscillation condition, TI recommends a maximum crystal equivalent
series resistance (ESR) of 50 Ω.
The TUSB8041 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.
2.2
USB Port Connectors
The TUSB8041 EVM is equipped with five standard 9-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, J3, J4, and 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.
The USB ports can be attached through a standard USB cable to any USB 3.0 or legacy USB host, hub,
or device. The TUSB8041 will automatically connect to any upstream USB 3.0 host or hub at both SS and
HS. Using a legacy USB cable between the TUSB8041 EVM and a USB 3.0 host or hub forces it to HS
operation. The same is true if a legacy USB cable is used between the TUSB8041 EVM and a
downstream SS-capable device; operation will be limited to USB 2.0 HS.
2.3
USB Port Connector – Power
VBUS is received from the upstream host or hub on J1. The TUSB8041 is configured as a self-powered
hub, so there is not any significant current draw by the EVM from VBUS. The TUSB8041 does monitor the
VBUS input after filtering through a resistor divider network of a 90.9-kΩ, 1% resistor, R2, and a 10-kΩ,
1% resistor, R3. VBUS cannot be directly connected to the TUSB8041 device. A bulk capacitor of at least
1 μF is required on the upstream port VBUS input to comply with the USB specification. The
TUSB8041EVM uses a 10-μF capacitor, C35.
VBUS, sourced by the 5-V wall power input, J6, is provided to the downstream port connectors. 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 TPS2001C devices, U7, U8, U9, and U10, is 2 A to avoid any spurious overcurrent
events due to bus-powered HDD spin-up power fluctuations or unnecessary limiting during USB charging.
A production implementation could place stricter limits on this power consumption. An overcurrent event
on any of the downstream port connectors will be reported to the TUSB8041 through the OVERCURxZ
inputs.
2.4
USB Port Connector – Noise Filtering
Each downstream VBUS output has a 150-μF bulk capacitor (C70, C71, C76, C79) as recommended by
the TPS2001C 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 TUSB8041EVM also implements optional isolation using two small noise filtering capacitors and a 1MΩ resistor 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.
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.
2.5
Optional Serial EEPROM
Each TUSB8041EVM is equipped with an onboard EEPROM/socket placeholder, U2. A small I2C
EEPROM can be installed to set the configuration registers as defined in the TUSB8041 data manual. 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 TUSB8041.

Hardware Overview
www.ti.com
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 TUSB8041 data sheet. In addition, a
Windows® based EEPROM utility is available upon request.
2.6
Power
The TUSB8041 EVM operates from the power provided by a 5-V wall power adapter, J5, not bus power
supplied by a USB host. TI recommends to use a wall power adapter that is capable of sourcing 2 to 3 A
because the hub must be able to source significant power on its downstream ports (900 mA per port).
The TUSB8041 EVM uses a single-channel LDO voltage regulator to drop 5 V to 3.3 V. The TPS7A4533,
U4, is a 1.5-A output linear regulator (SLVS720). The 1.1-V core voltage required by the TUSB8041 is
sourced by the 3.3-V rail to reduce unnecessary heat dissipation. The TPS74801, U6, 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.
2.7
Hub Configuration
The TUSB8041EVM can be configured by setting several inputs to the TUSB8041 that are sampled at
power-on reset or using an optional serial EEPROM or SMBUS host. A production implementation without
EEPROM or SMBUS could either rely on the default internal pullup or pulldown resistor for each
configuration input or override it with an external pullup or pulldown resistor. The settings can be modified
using SW1 and SW2 on the EVM. Descriptions of the possible configuration changes are included in a
later section.
2.8
Optional Circuitry
The TUSB8041 EVM design implements a variety of LEDs, none of which are required by the USB
specification. They are provided to make testing and debugging easier.
• D1 – indicates that the upstream USB port is connected at HS.
• D2 – indicates that the downstream USB port 2 is connected at SS.
• D3 – indicates that the downstream USB port 1 is connected at SS.
• D4 – indicates that the upstream USB port is connected at SS.
• D5 – indicates that 5 V is being applied to the TUSB8041 EVM.
• D6 – indicates downstream USB port 1 power is on.
• D7 – indicates downstream USB port 2 power is on.
• D8 – indicates BOARD_3P3V is active.
The switches (SW1, SW2, and SW3) and headers (J7, J8, J9, JP6) present on the TUSB8041 EVM are
intended only for lab evaluation and are not required for production designs.

Hardware Setup
3.1
Configuration Switch
The TI TUSB8041EVM has a set of switches to facilitate configuration changes. TI does not recommend
changing these switch settings without a complete understanding of the result. Configuration inputs are
only read by the TUSB8041 during power-on reset, changing the switch settings while the EVM is
powered on will have no effect. For additional information, refer to the EVM schematic in Section B.1.
The switch definitions are as follows in Table 1.

install the EVM, perform the following steps:
Attach a 5-V 3-A wall power source to J5. LED D5 should be lit.
Turn on switch SW3, LED D8 should be lit.
Attach a USB cable between J3 and a USB host. LEDs D6 and D7 should be lit.
(a) If the TUSB8041EVM is attached to a USB 3.0 host, D1 and D4 should be lit.
(b) If the TUSB8041EVM is attached to a USB 2.0 host, D1 should be lit.
Troubleshooting
Case 1: Device function or functions 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 to support any bus-powered devices (3 A+).
• If installed, remove the serial EEPROM from the EEPROM socket. The EVM does not require an
EEPROM to operate.
• Make sure shunts are installed on J7, J8, and J9.
• In the case where a 12-V power supply has been attached to the EVM, the fault is non-recoverable.

ADDITIONAL TERMS AND CONDITIONS, WARNINGS, RESTRICTIONS, AND DISCLAIMERS FOR
EVALUATION MODULES
Texas Instruments Incorporated (TI) markets, sells, and loans all evaluation boards, kits, and/or modules (EVMs) pursuant to, and user
expressly acknowledges, represents, and agrees, and takes sole responsibility and risk with respect to, the following:
1.
User agrees and acknowledges that EVMs are intended to be handled and used for feasibility evaluation only in laboratory and/or
development environments. Notwithstanding the foregoing, in certain instances, TI makes certain EVMs available to users that do not
handle and use EVMs solely for feasibility evaluation only in laboratory and/or development environments, but may use EVMs in a
hobbyist environment. All EVMs made available to hobbyist users are FCC certified, as applicable. Hobbyist users acknowledge, agree,
and shall comply with all applicable terms, conditions, warnings, and restrictions in this document and are subject to the disclaimer and
indemnity provisions included in this document.
2. Unless otherwise indicated, EVMs are not finished products and not intended for consumer use. EVMs are intended solely for use by
technically qualified electronics experts who are familiar with the dangers and application risks associated with handling electrical
mechanical components, systems, and subsystems.
3. User agrees that EVMs shall not be used as, or incorporated into, all or any part of a finished product.
4. User agrees and acknowledges that certain EVMs may not be designed or manufactured by TI.
5. User must read the user's guide and all other documentation accompanying EVMs, including without limitation any warning or
restriction notices, prior to handling and/or using EVMs. Such notices contain important safety information related to, for example,
temperatures and voltages. For additional information on TI's environmental and/or safety programs, please visit www.ti.com/esh or
contact TI.
6. User assumes all responsibility, obligation, and any corresponding liability for proper and safe handling and use of EVMs.
7. Should any EVM not meet the specifications indicated in the user’s guide or other documentation accompanying such EVM, the EVM
may be returned to TI within 30 days from the date of delivery for a full refund. THE FOREGOING LIMITED WARRANTY IS THE
EXCLUSIVE WARRANTY MADE BY TI TO USER AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED, IMPLIED, OR
STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE. TI SHALL
NOT BE LIABLE TO USER FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES RELATED TO THE
HANDLING OR USE OF ANY EVM.
8. No license is granted under any patent right or other intellectual property right of TI covering or relating to any machine, process, or
combination in which EVMs might be or are used. TI currently deals with a variety of customers, and therefore TI’s arrangement with
the user is not exclusive. TI assumes no liability for applications assistance, customer product design, software performance, or
infringement of patents or services with respect to the handling or use of EVMs.
9. User assumes sole responsibility to determine whether EVMs may be subject to any applicable federal, state, or local laws and
regulatory requirements (including but not limited to U.S. Food and Drug Administration regulations, if applicable) related to its handling
and use of EVMs and, if applicable, compliance in all respects with such laws and regulations.
10. User has sole responsibility to ensure the safety of any activities to be conducted by it and its employees, affiliates, contractors or
designees, with respect to handling and using EVMs. Further, user is responsible to ensure that any interfaces (electronic and/or
mechanical) between EVMs and any human body are designed with suitable isolation and means to safely limit accessible leakage
currents to minimize the risk of electrical shock hazard.
11. User shall employ reasonable safeguards to ensure that user’s use of EVMs will not result in any property damage, injury or death,
even if EVMs should fail to perform as described or expected.
12. User shall be solely responsible for proper disposal and recycling of EVMs consistent with all applicable federal, state, and local
requirements.
Certain Instructions. User shall operate EVMs within TI’s recommended specifications and environmental considerations per the user’s
guide, accompanying documentation, and any other applicable requirements. Exceeding the specified ratings (including but not limited to
input and output voltage, current, power, and environmental ranges) for EVMs may cause property damage, personal injury or death. If
there are questions concerning these ratings, user should contact a TI field representative prior to connecting interface electronics including
input power and intended loads. Any loads applied outside of the specified output range may result in unintended and/or inaccurate
operation and/or possible permanent damage to the EVM and/or interface electronics. Please consult the applicable EVM user's guide prior
to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During
normal operation, some circuit components may have case temperatures greater than 60°C as long as the input and output are maintained
at a normal ambient operating temperature. These components include but are not limited to linear regulators, switching transistors, pass
transistors, and current sense resistors which can be identified using EVMs’ schematics located in the applicable EVM user's guide. When
placing measurement probes near EVMs during normal operation, please be aware that EVMs may become very warm. As with all
electronic evaluation tools, only qualified personnel knowledgeable in electronic measurement and diagnostics normally found in
development environments should use EVMs.
Agreement to Defend, Indemnify and Hold Harmless. User agrees to defend, indemnify, and hold TI, its directors, officers, employees,
agents, representatives, affiliates, licensors and their representatives harmless from and against any and all claims, damages, losses,
expenses, costs and liabilities (collectively, "Claims") arising out of, or in connection with, any handling and/or use of EVMs. User’s
indemnity shall apply whether Claims arise under law of tort or contract or any other legal theory, and even if EVMs fail to perform as
described or expected.
Safety-Critical or Life-Critical Applications. If user intends to use EVMs in evaluations of safety critical applications (such as life support),
and a failure of a TI product considered for purchase by user for use in user’s product would reasonably be expected to cause severe
personal injury or death such as devices which are classified as FDA Class III or similar classification, then user must specifically notify TI
of such intent and enter into a separate Assurance and Indemnity Agreement.
RADIO FREQUENCY REGULATORY COMPLIANCE INFORMATION FOR EVALUATION MODULES
Texas Instruments Incorporated (TI) evaluation boards, kits, and/or modules (EVMs) and/or accompanying hardware that is marketed, sold,
or loaned to users may or may not be subject to radio frequency regulations in specific countries.
