SCES790 – JUNE 2009 ADVANCED UNIVERSAL SERIAL BUS TRANSCEIVER • 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 is Ideal for Portable Equipment • Meets the IEC-61000-4-2 Contact Discharge (±9 kV) and Air-Gap Discharge (±9 kV) 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 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. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
