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).
