7 Detailed Description
7.1 Overview
The TUSB213 is a USB High-Speed (HS) signal conditioner, designed to compensate for ISI signal loss in a
transmission channel. TUSB213 has a patent-pending design which is agnostic to USB Low Speed (LS) and Full
Speed (FS) signals and does not alter their signal characteristics, while HS signals are compensated. In addition,
the design is compatible with USB On-The-Go (OTG) and Battery Charging (BC) specifications.
Programmable signal AC boost through an external resistor on EQ pin permits fine tuning device performance to
optimize signals helping to pass USB HS electrical compliance tests at the connector. Additional DC Boost
configurable by three level input DC_BOOST pin helps overcoming the cable losses.

7.3 Feature Description
7.3.1 EQ
The EQ pin of the TUSB213 is used to configure the AC boost of the device. The four levels of AC boost are set
through different values of an external pulldown resistor at this pin.
7.3.2 DC BOOST
The DC_BOOST pin of the TUSB213 is a tri-level pin, used to set the DC gain of the device according to 表 1.

Device Functional Modes (接下页)
7.4.3 High Speed (HS) Mode
TUSB213 automatically detects a HS connection and will enable signal compensation as determined by the
configuration of the DC_BOOST pin and the external pulldown resistance on its EQ pin. CD pin asserted high.
7.4.4 Shutdown Mode
TUSB213 is disabled when its RSTN pin is asserted low. In shutdown mode, the USB channel is still fully
operational but there is neither signal compensation nor any indication from the CD pin as to the status of the
channel.
7.4.5 I2C Mode
TUSB213 support 100 kHz I2C for device configuration, status readback and test purposes. This controller is
enabled after SCL and SDA pins are sampled high shortly after de-assertion of RSTN. In this mode, the register
as described in 表 2 can be accessed by I2C read/write transaction to 7-bit slave address 0x2C. It is necessary to
set CFG_ACTIVE bit and reset it to zero after making changes to the EQ and DC Boost level registers to restart
the state machine.
注
All registers or fields in 表 2 which are not specifically mentioned are considered reserved.
The default value of these reserved registers or fields must not be changed. It is
suggested to perform a read-modify-write operation to maintain the default value of the
reserved fields.

8 Application and Implementation
注
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The primary purpose of the TUSB213 is to re-store the signal integrity of a USB High Speed channel up to the
USB connector. The loss in signal quality stems from reduced channel bandwidth due to high loss PCB trace and
other components that contribute a capacitive load. This can cause the channel to fail the USB near end eye
mask. Proper use of the TUSB213 can help to pass this eye mask. Additionally the DC Boost helps overcoming
DC losses from cables and traces.
A secondary purpose is to use the CD pin of the TUSB213 to control other blocks on the customer platform if so
desired.
8.2 Typical Application
A typical application is shown in 图 6. In this setup, D2P and D2M face the USB connector while D1P and D1M
face the USB host or hub. If desired, the orientation may be reversed [that is, D2 faces transceiver and D1 faces
connector].

8.2.2 Detailed Design Procedure
TUSB213 requires a valid reset signal as described in the power supply recommendations section. The capacitor
at RSTN pin is not required if a microcontroller drives the RSTN pin according to recommendations.
VREG pin is the internal LDO output that requires a 0.1-μF external capacitor to GND to stabilize the core.
The ideal AC boost setting is dependent upon the signal chain loss characteristics of the target platform. The
general recommendation is to start with AC boost level 0, and then increment to AC boost level 1, etc. if
permissible. Same applies to the DC Boost setting where it is recommended to plan for the required pads or
connections to change boost settings, but to start with DC boost level 1.
In order for the TUSB213 to recognize any change to the AC and DC Boost settings, the RSTN pin must be
toggled. This is because the configuration is latched on power up and the inputs are ignored thereafter.
注
The TUSB213 compensates for DC attenuation in the signal path according to the
configuration of the DC_BOOST pin. This pin is not 5V tolerant and therefore when
selecting the highest DC boost level, the voltage level at DC_BOOST pin must be less
than 3.6V.
Placement of the device is also dependent on the application goal. 表 4 summarizes our recommendations.

8.2.2.1 Test Procedure to Construct USB High Speed Eye Diagram
注
USB-IF certification tests for High Speed eye masks require the mandated use of the
USB-IF developed test fixtures. These test fixtures do not require the use of oscilloscope
probes. Instead they use SMA cables. More information can be found at the USB-IF
Compliance Updates Page. It is located under the ‘Electricals’ section, ID 86 dated March
2013.
The following procedure must be followed before using any oscilloscope compliance software to construct a USB
High Speed Eye Mask:
8.2.2.1.1 For a Host Side Application
1. Configure the TUSB213 to the desired AC and DC Boost settings
2. Power on (or toggle the RSTN pin if already powered on) the TUSB213
3. Using SMA cables, connect the oscilloscope and the USB-IF host-side test fixture to the TUSB213
4. Enable the host to transmit USB TEST_PACKET
5. Execute the oscilloscope USB compliance software.
6. Repeat the above steps in order to re-test TUSB213 with a different settings
8.2.2.1.2 For a Device Side Application
1. Configure the TUSB213 to the desired AC and DC Boost settings
2. Power on (or toggle the RSTN pin if already powered on) the TUSB213
3. Connect a USB host, the USB-IF device-side test fixture, and USB device to the TUSB213. Ensure that the
USB-IF device test fixture is configured to the ‘INIT’ position
4. Allow the host to enumerate the device
5. Enable the device to transmit USB TEST_PACKET
6. Using SMA cables, connect the oscilloscope to the USB-IF device-side test fixture and ensure that the
device-side test fixture is configured to the ‘TEST’ position.
7. Execute the oscilloscope USB compliance software.
8. Repeat the above steps in order to re-test TUSB213 with a different settings

9 Power Supply Recommendations
On power up, the interaction of the RSTN pin and power on ramp could result in digital circuits not being set
correctly. The device should not be enabled until the power on ramp has settled to 4.4 V or higher to ensure a
correct power on reset of the digital circuitry. If RSTN cannot be held low by microcontroller or other circuitry until
the power on ramp has settled, then an external capacitor from the RSTN pin to GND is required to hold the
device in the low power reset state.
The RC time constant should be larger than five times of the power on ramp time (0 to VCC). With a typical
internal pullup resistance of 500 kΩ, the recommended minimum external capacitance is calculated as:
CRSTN = [Ramp Time × 5] ÷ [500 kΩ]

10 Layout
10.1 Layout Guidelines
To avoid the need for signal vias, it is highly recommend to route the High Speed traces on the same surface
layer than the TUSB213 is placed. shows an example how one could layout the PCB for TUSB213.
The layout should use impedance controlled traces to maintain 90 Ω differential impedance for the whole signal
path as required per USB 2.0 specification. General guidelines for highspeed signal routing apply.
