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 operate at lower input supply voltages (VCC = 1.65V), increasing power efficiency. The device also features low power consumption, making it ideal for portable equipment.
