Description

The PI3CSW12 is a high-bandwidth switch specially designed for

the switching of high-speed I3C signals in communication and

server applications, such as servers, workstations, and notebooks

with hubs or controllers with limited I3C I/Os. The wide bandwidth

(1.6GHz) of this switch allows signals to pass with minimum edge

and phase distortion. The device multiplexes differential outputs

from a I3C 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 and high channel-to-channel noise isolation, and is

compatible with various standards, such as high-speed I3C (up to

30Mbps).
