Description
ThePI3USB20isa8-to4-Channelmultiplexer/demultiplexerVideo
Switch with Hi-Z outputs. Industry leading advantages include a
propagation delay of less than 250ps, resulting from its low channel
resistance and I/O capacitance.
ThedevicemultiplexesdifferentialoutputsfromaUSBHostdevice
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, high channel-to-
channel noise isolation and is compatible with various standards,
such as high speed USB 2.0 (480 Mb/s).
