PI3USB31531

Description

The PI3USB31531 is a 6:4 differential channel bidirectional Crossbar switch solution for switching USB3.1 Gen1/Gen2 (-3db @ 10Gb/s) and/or DP1.2/DP1.4 (-3.7db @ 8Gb/s) signals through USB3.0 Type-C connector.

It multiplexes either one lane of USB3.1 Gen1/Gen2, one lane of USB3.1 Gen1/Gen2 and two channels of DP1.2/1.4, or four channels of DP1.2/DP1.4 to the USB Type-C connector.

In addition, AUX+/- channels are also multiplexed to the Type-C connector. PI3USB31531 offers excellent signal integrity for high-speed signals and low power dissipation. Insertion loss is -3dB, and return loss is -15dB (TBD) at 10Gb/s speed of USB3.1.
