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).
