Description
The PI3USB20 is a 8- to 4-Channel multiplexer/demultiplexer Video
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.
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, high channel-to-
channel noise isolation and is compatible with various standards,
such as high speed USB 2.0 (480 Mb/s).
