Description
The PI3USB40 is a 16- to 8-channel multiplexer/demultiplexer
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 transceiver 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).
Applications
• Routes physical layer signals for high-speed, high
bandwidth differential protocols
