3 Description
The TS3USB221 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 (1.1 GHz) of this switch allows signals to
pass with minimum edge and phase distortion. The
device multiplexes differential outputs from a USB
host device to one of two corresponding outputs. The
switch is bidirectional and offers little or no
attenuation of the high-speed signals at the outputs.
The TS3USB221 is designed for low bit-to-bit skew
and high channel to channel noise isolation. The
TS3USB221 is also compatible with various
standards, such as high-speed USB 2.0 (480 Mbps).
