Pericom Semiconductor’s PI3USB31532 is a 6:4 differential channel bi-directional Crossbar switch solution for switching USB3.1 Gen1/Gen2 and/or DP1.2/DP1.3 signals through
USB3.0 Type-C connector.
It multiplexes either 1 lane of USB3.1 Gen1/Gen2, 1 lane of USB3.1 Gen1/Gen2 and 2 channels of DP1.2/1.3 or 4 channels of DP1.2/DP1.3 to the USB Type-C™ connector.
In addition, AUXHPD 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 USB3.1.
