PI3USB10M
4.2V, Wide Bandwidth, 2-Channel,
2:1 Mux/DeMux USB 2.0 Switch w/ Single Select
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).
