Description

FSUSB20 is a low-power, high-bandwidth switch specially designed for switching high-speed USB 2.0 signals in handset and consumer applications; such as cell phone, digital camera, and notebook with hubs or controllers of limited USB I/O. The wide bandwidth (>720MHz) allows signals to pass with minimum edge and phase distortion. S uperior channel-to-channel crosstalk results in minimal in terference. It is compatible with the high-speed USB 2.0 standard.

The devic e may not function or be operable above the recommended operating c onditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Symbol Parameter Min. Max.

Measured by the voltage drop between the A and B pins at the indicated current through the switch. On resistance is determined by the lower of the voltages on the A or B pins. 4. Flatness is defines as the di fference between the maximum and the minimum value on resistance over the specified range of conditions.
