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.
