• 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).
