DESCRIPTION/ORDERING INFORMATION
TUSB2551
ADVANCED UNIVERSAL SERIAL BUS TRANSCEIVER
SCES667 – FEBRUARY 2008
www.ti.com
• Complies With Universal Serial Bus
Specification Rev. 2.0 (USB 2.0)
• Transmits and Receives Serial Data at Both
Full-Speed (12-Mbit/s) and Low-Speed
(1.5-Mbit/s) Data Rates
• Integrated Bypassable 5-V to 3.3-V Voltage
Regulator for Powering Via USB VBUS
• Low-Power Operation, Ideal for Portable
Equipment
• Meets the IEC-61000-4-2 Contact (±9KV) and
Air-gap (±9KV) ESD Ratings
• Separate I/O Supply With Operation Down to
1.65 V
• Very-Low Power Consumption to Meet USB
Suspend Current Requirements
• No Power-Supply Sequencing Requirements
• Cellular Phones
• Personal Digital Assistants (PDAs)
• Handheld Computers
The TUSB2551 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
TUSB2551 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 TUSB2551 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.
