PI3USB221
High-Speed USB2.0 1:2 Multiplexer/
DeMultiplexer Switch with Signal Enable
Description
The PI3USB221 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. 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).
