Description

The PI3USB10M is a single differential channel 2:1 multiplexer/

demultiplexer USB 2.0 Switch. Industry leading advantages in-

clude 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 cor-

responding 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).
