Introduction
The Texas Instruments TUSB4020B evaluation module is a functional board design of a single device that
implements a USB 2.0 hub. The EVM can support 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 TUSB4020B.
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

Hardware Overview
The TUSB4020B EVM board hardware can be divided into six functional areas:
2.1
TUSB4020BPHP
The TUSB4020B EVM (U2 on the schematic) operates as a functional interconnect between an upstream
connection to a USB host or hub and up to two directly connected downstream devices or hubs. More
devices and hubs can be supported if arranged in tiers. The TUSB4020B is capable of supporting
operation at High-Speed (HS), Full Speed (FS) or Low Speed (LS). In general, the speed of the upstream
connection of the TUSB4020B EVM limits the downstream connections to that speed (HS and FS) or
lower.
The TUSB4020B 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 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 Ω is recommended.
The TUSB4020B 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
VBUS is received from the upstream host or hub on J3. The TUSB4020B is configured as a self-powered
hub, so there is not any significant current draw by the EVM from VBUS. The TUSB4020B does monitor
the VBUS input after filtering through a resistor divider network of a 90.9-kΩ, 1% resistor, R9, and a 10kΩ, 1% resistor, R10. VBUS cannot be directly connected to the TUSB4020B device. A bulk capacitor of
at least 1 μF is required on the upstream port VBUS input to comply with the USB specification. The
TUSB4020BEVM uses a 10-μF capacitor, C8.
VBUS, sourced by the 5-V wall power input, J5, is provided to the downstream port connectors. The USB
2.0 specification limits the current consumption of a USB 2.0 device to 500 mA at 5 V. The current limiting
parameter of the TPS2561 device, U3, is configured to 2.2 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 TUSB4020B via the OVERCURxZ inputs.
2.2.1
USB Port Connector – Noise Filtering
Each downstream VBUS output has a 150-μF bulk capacitor (C49, C51) as recommended by the
TPS2561 data manual (SLVS930) 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 TUSB4020BEVM 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.
2.3
Optional Serial EEPROM
Each TUSB4020BEVM is equipped with an onboard EEPROM/socket placeholder, U1. A small I2C
EEPROM can be installed to set the configuration registers as defined in the TUSB4020B 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 TUSB4020B.
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 TUSB4020B data sheet (#NUM#). In
addition, a Microsoft® Windows® based EEPROM utility is available upon request.

Hardware Overview
2.4
www.ti.com
Power
The TUSB4020B EVM operates from the power provided by a 5-V wall power adapter, J5, 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 (500 mA per port).
The TUSB4020B 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
TUSB4020B is sourced by the 3.3-V rail to reduce unnecessary heat dissipation. The TPS74801, U5, 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.
2.5
Hub Configuration
The TUSB4020BEVM can be configured by setting several inputs to the TUSB4020B 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 pull-up or pull-down resistor for each
configuration input or override it with an external pull-up or pull-down resistor. The settings can be
modified using SW1 on the EVM. Descriptions of the possible configuration changes are included in the
Configuration Switch section.
2.6
Optional Circuitry
The TUSB4020B EVM design implements a variety of LEDs, none of which are required by the USB
specification. The LEDs are provided for easier testing and debug.
• D1 – Indicates that the upstream USB port is connected at High-Speed
• D5 – Indicates that 5 V is being applied to the TUSB4020B 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

Hardware Set Up
3.1
Configuration Switch
The TI TUSB4020BEVM has a set 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 TUSB4020B during power on reset, changing the switch settings while the EVM is powered on
will have no effect. Please refer to the EVM schematic in Appendix B for additional information.
The switch definitions are as follows, with the standard setting in parenthesis:
SW1_1 (on):
SW1_2 (off):
SW1_3 (off):
SW1_4 (on):
SW1_5 (off):
SW1_6 (off):
SW1_7 (off):
SW1_8(off):
FULLPWRMGMTZ_SMBA1_SS Switch. The TUSB4020B has an internal pull up on
this terminal, so the TUSB4020B 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 TUSB4020B reports that it supports downstream
port power switching in the USB descriptors it sends to the USB host. Since the
TUSB4020B EVM does implement downstream port power switching, full power
management mode should be enabled.
PWRCTL_POL_SS_DN1 Switch. The TUSB4020B has an internal pull down on this
terminal, so port power control polarity defaults to active high. If the switch is set to the
ON position, the terminal is pulled high and the port power control polarity changes to
active low.
SMBUSz_SS_DN2 Switch. The TUSB4020B 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.
GANGED_SMBA2_HS Switch. The TUSB4020B has an internal pull up on this
terminal, so ganged mode is enabled by default. If the switch is set to the ON position,
the terminal is pulled low and individual port power control mode is enabled. Since the
TUSB4020B EVM does implement individual port power controls, this terminal should
be set high.
SCL_SMBCLK_SSCDIS Switch. The TUSB4020B 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).
SDA_SMBDAT_U1U2DIS Switch. The TUSB4020B 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).
PWRCTL1_BATEN1 Switch. The TUSB4020B 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.
PWRCTL2_BATEN2 Switch. The TUSB4020B has an internal pull down on this
terminal, so the 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.

www.ti.com
EVM Installation
Install the EVM with the following steps:
1. Attach a 5-V, 3-A wall power source to J5. LEDs D8 and D5 should be lit.
2. Attach a USB cable between J3 and a USB host. LEDs D1, D6, and D7 should be lit.
5
Troubleshooting
Use the following to troubleshoot issues:
Case 1: One or more device 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 (3A+)
• 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
