• 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

operate at its core voltage without the addition of buffering logic, and also reduce system operating current.
