PI3CSW12 I3C 1:2 Multiplexer Diodes Incorporated PI3CSW12 I3C 1:2 Multiplexer 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 1.6GHz bandwidth of the PI3CSW12 allows signals to pass with minimum edge and phase distortion. The device multiplexes differential outputs from an 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 bitto-bit skew and high channel-to-channel noise isolation and is compatible with various standards, such as high-speed I3C (up to 30Mbps).
