Diodes Incorporated PI3USB30532 is a 6:4 differential channel
bi-directional matrix switch solution for switching USB3.0 and/or
DP1.2 signals through USB3.0 Type-C connector.
It multiplexes either 1 lane of USB3.0, 1 lane of USB3.0 and 2 channels
of DP1.2 or 4 channels of DP1.2 to the USB Type C connector.
In addition, AUX± channels are also multiplexed to the Type C
connector. PI3USB30532 offers excellent signal integrity for
high-speed signals and low power dissipation. Insertion loss is
-1.2dB and return loss is -21dB at 5Gb/s speed of USB3.0.
