The DIODES™ PI3USB31532 is a 6:4 differential channel, bidirectional, crossbar switch solution for switching USB 3.2 Gen 1/Gen 2 and/or DP 2.1 signals through USB 3.2 Gen 2 Type-C connector. It multiplexes either one lane of USB 3.2 Gen 1/Gen 2, one lane of USB 3.2 Gen 1/Gen 2, and two channels of DP 2.1 UHBR10 or four channels of DP 2.1 UHBR10 to the USB Type-C connector.

In addition, AUX± channels are also multiplexed to the Type-C connector. The 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 2 and DP 2.1 UHBR10.
