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
N.C. - No internal connection
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).
