DESCRIPTION/ORDERING INFORMATION
The TUSB2551A is a single-chip transceiver that complies with the physical-layer specifications of universal
serial bus (USB) 2.0. The device supports both full-speed (12-Mbit/s) and low-speed (1.5-Mbit/s) operation. The
TUSB2551A delivers superior edge-rate control, producing crisper eye diagrams, which ease the task of passing
USB compliance testing.
A dual supply-voltage operation allows the TUSB2551A to reference the system interface I/O signals to a supply
voltage down to 1.6 V, while independently powered by the USB VCC(5.0). This allows the system interface to
operate at its core voltage without the addition of buffering logic, and also reduce system operating current.

SCES790 – JUNE 2009...................................................................................................................................................................................................... www.ti.com
Power-Supply Configurations
The TUSB2551A can be used with different power-supply configurations, which can be dynamically changed. An
overview is given in Table 1.
• Normal mode – Both VCC(I/O) and VCC(5.0) or VCC(5.0) and Vreg(3.3) are connected. For 5-V operation, VCC(5.0) is
connected to a 5-V source (4 V to 5.5 V). The internal voltage regulator then produces 3.3 V for the USB
connections. For 3.3-V operation, both VCC(5.0) and Vreg(3.3) are connected to a 3.3-V source (3 V to 3.6 V).
VCC(I/O) is independently connected to a voltage source (1.65 V to 3.6 V), depending on the supply voltage of
the external circuit.
• Disable mode – VCC(I/O) is not connected; VCC(5.0) or VCC(5.0) and Vreg(3.3) are connected. In this mode, the
internal circuits of the TUSB2551A ensure that the D+ and D– pins are in 3-state, and the power consumption
drops to the low-power (suspended) state level. Some hysteresis is built into the detection of VCC(I/O) lost.
• Sharing mode – VCC(I/O) is connected; VCC(5.0) and Vreg(3.3) are not connected. In this mode, the D+ and D–
pins are made 3-state, and the TUSB2551A allows external signals of up to 3.6 V to share the D+ and D–
lines. The internal circuits of the TUSB2551A ensure that virtually no current (maximum 10 mA) is drawn via
the D+ and D– lines. The power consumption through VCC(I/O) drops to the low-power (suspended) state level.
Both the VP and VM pins are driven HIGH to indicate this mode. Pin RCV is made LOW. Some hysteresis is
built into the detection of Vreg(3.3) lost.

Power-Supply Input Options
The TUSB2551A has two power-supply input options.
• Internal regulator – VCC(5.0) is connected to 4 V to 5.5 V. The internal regulator is used to supply the internal
circuitry with 3.3 V (nominal). Vreg(3.3) becomes a 3.3-V output reference.
• Regulator bypass – VCC(5.0) and Vreg(3.3) are connected to the same supply. The internal regulator is bypassed,
and the internal circuitry is supplied directly from the Vreg(3.3) power supply. The voltage range is
3 V to 3.6 V to comply with the USB specification.
The supply-voltage range for each input option is specified in Table 3.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,
and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a
warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual
property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied
by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
