• Routes Signals for USB 1.0, 1.1, and 2.0

The TS3USB31 is a high-bandwidth switch specially

designed for the switching of high-speed USB 2.0

signals in handset and consumer applications, such

as cell phones, digital cameras, and notebooks with

hubs or controllers with limited USB I/Os. The wide

bandwidth (750 MHz) of this switch allows signals to

pass with minimum edge and phase distortion. The

switch is bidirectional and offers little or no

attenuation of the high-speed signals at the outputs. It

is designed for low bit-to-bit skew and high

channel-to-channel noise isolation, and is compatible

with various standards, such as high-speed USB 2.0

(480 Mbps).
