Description

Pericom Semiconductor’s PI3USB3102 USB3.0 and USB2.0 Com-

bo Switch is a complete 1:2 switching solution for SuperSpeed

USB 3.0 signals. PI3USB3102 provides differential high-speed

lanes for the USB3.0 4.8 Gbps TX and RX lanes as well as a differ-

ential lane for 480 Mbps USB 2.0 signals and the USB_ID signal.

PI3USB3102 can be used to connect two hosts to a single device

or a single host to two devices.

PI3USB3102 offers excellent signal integrity for high-speed sig-

nals and low power dissipation. Insertion loss is 1.7 dB and return

loss is -16 dB at 2.5 GHz. Power dissipation is 6.6 mW maximum.

Application

Routing of USB3.0 signals with low signal attenuation between

source and sink.
