USB 3.2 Gen 2/Display Port 1.4 Crossbar Switch for Type-C


The PI3USB31532 is a 6:4 differential channel bi-directional Crossbar switch solution for switching USB 3.2 Gen 1/Gen 2 and/or  DP1.2/DP1.4 signals through USB 3.2 Gen 1/Gen 2 Type-C™ connector.
It multiplexes either 1 lane of USB 3.2 Gen 1/Gen 2, 1 lane of USB 3.2 Gen 1/Gen 2 and 2 channels of DP1.2/1.4 or 4 channels of DP1.2/DP1.4 to the USB Type-C™ connector.

In addition, AUX+/- channels are also multiplexed to the Type-C connector.  PI3USB31532 offers excellent signal integrity for high-speed signals and low power dissipation. Insertion loss is -1.7dB and return loss is  -15dB at 10Gb/s speed of USB 3.2 Gen 1/Gen 2 .
