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.
