1 TUSB216EVM
The TUSB216 is a USB High-Speed signal conditioner, designed to compensate for ISI signal loss in a
transmission channel.
The TUSB216 design is agnostic to USB Low and Full-Speed signals and does not affect FS and LS
signaling. High-Speed signals are compensated along with programmable DC gain to fine-tune device
performance to optimize the High-Speed signals at the connector.
This EVM was designed to be used as a medium connection between a USB host and a USB device. The
EVM is designed to provide multiple connector options to help eliminate the use of adapters. The interface
to the EVM consists of three input connectors: a USB 3.1 Mini-B Receptacle, a USB 3.1 Type B
Receptacle, and a USB 3.1 Type-A Plug. The interface to the EVM consists of three a USB 3.1 Type-A
Receptacle output connectors. Each section of the EVM is detachable from the main board along the
board perforations. The EVM can be connected to the system in a similar fashion in Figure 1 .

3 Description of EVM Board
The TUSB216 EVM is designed to provide easy evaluation of the TUSB216 device. It is also meant to
serve as a reference design to show a practical example of how to use the device in a mass-production
system. Figure 2 highlights the jumpers and switch installed on this EVM .
Figure 2. TUSB216EVM
4 TUSB216EVM Jumper and Switch Configuration
The TUSB216 has three switches and six set of jumpers to facilitate configuration changes. The "BOOST"
and EX_ENA_HS jumpers are arranged in a plus shape to allow for easy configuration. Changing these
switch and jumpers settings without a complete understanding of the result is not recommended.
Configuration inputs are only read by the TUSB216 during power on reset or after de-asserting the RSTN
pin, changing these switch settings while the EVM is powered on has no effect. Refer to the device
datasheet for detailed pin descriptions and functionality along with EVM schematic for additional
information.
The switch definitions are as follows:
RSTN Push button Switch (SW1, SW2, SW3):
• Push button to place TUSB216 device in RESET
• Release to de-assert RESET
"BOOST" Jumper Settings:
1. Bottom position sets TUSB216 BOOST Level 0
2. Left position sets TUSB216 to BOOST Level 1
3. Top position sets TUSB216 to BOOST Level 2
4. No connect "BOOST" jumper sets TUSB216 to BOOST Level 3
Right Position of BOOST Jumper is short to GND.

"RX_ENA_HS" Jumper Settings:
1. Top position sets low RX sensitivity.
2. No connect RX_ENA_HS jumper sets mid RX sensitivity
3. Left position sets high RX sensitivity
4. Bottom position must be set to use ENA_HS LED indicator.
Right Position of RX_ENA_HS jumper is short to GND.
5 Selecting Equalization / Boost Level for TUSB216
The primary purpose of the TUSB216 is to restore the signal integrity of a USB High-Speed channel up to
the USB connector. The platform goal is to pass the USB Near-End or Far-End Eye Mask with the
TUSB216 in the best location.
A typical use case is to place the TUSB216 close to the USB connector on a Host platform to pass Near-
End Eye Mask testing. This includes systems where the USB connector may be placed at the Far-End of
a cable.
Typical EQ and Boost recommendations based on cable length (28 AWG USB Cable).
Table 1. EQ/Boost Setting Based on Cable Length
CABLE LENGTH TUSB216 BOOST TUSB216 RX SEN
0m - 1m EQ1 MID
1m – 2m EQ2 MID
2m – 3m EQ2 HIGH
3m – 5m EQ3 HIGH
6 EVM Operation
To install the EVM, perform the following steps:
1. Attach a USB2 or USB3 cable from a Host PC Type A connector to the Type B connector (P4) of the
TUSB216 EVM.
2. Attach a USB device either via cable or directly plugged into the Type A receptacle connector (P3) on
the TUSB216 EVM.
NOTE: TUSB216EVM does not include I2C pull-up resistors. If I2C access is desired external pull-
up resistor to 3.3V are required.

warranted for the remainder of the original warranty period. Replaced EVMs shall be warranted for a new full ninety (90) day
warranty period.
WARNING
Evaluation Kits are intended solely for use by technically qualified,
professional electronics experts who are familiar with the dangers
and application risks associated with handling electrical mechanical
components, systems, and subsystems.
User shall operate the Evaluation Kit within TI’s recommended
guidelines and any applicable legal or environmental requirements
as well as reasonable and customary safeguards. Failure to set up
and/or operate the Evaluation Kit within TI’s recommended
guidelines may result in personal injury or death or property
