DESCRIPTION/ORDERING INFORMATION
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 V
CC(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.
