Description
Pericom Semiconductor鈥檚 PI3USB series of logic circuits are
produced using the Company鈥檚 advanced sub-micron CMOS
technology, achieving industry leading performance.
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).
Application
鈥?Routes signals for USB 2.0
