PI3USB3102 USB3.0 and USB2.0 Combo Switch Features Description 1:2 mux/demux for USB 3.0SS, 2.0HS, and 2.0FS signals Pericom Semiconductors PI3USB3102 USB3.0 and USB2.0 Com- bo Switch is a complete 1:2 switching solution for SuperSpeed Switches Tx, Rx, Dx, and USB ID from USB3.0 connector USB 3.0 signals. PI3USB3102 provides differential high-speed Insertion Loss for superspeed channels 2.5 GHz: -1.7dB lanes for the USB3.0 4.8 Gbps TX and RX lanes as well as a differ - -3dB Bandwidth for superspeed channels: 4.7GHz ential lane for 480 Mbps USB 2.0 signals and the USB ID signal. Return loss for superspeed channels 2.5GHz: -16dB Low Bit-to-Bit Skew, 7ps max (between + and - bits) PI3USB3102 can be used to connect two hosts to a single device Low Crosstalk for superspeed channels: -25dB 5.0 Gbps or a single host to two devices. Low Off Isolation for superspeed channels: -25dB 5.0 Gbps V Operating Range: 3.3V +/-10% DD PI3USB3102 offers excellent signal integrity for high-speed sig - nals and low power dissipation. Insertion loss is 1.7 dB and return ESD Tolerance: 2kV HBM loss is -16 dB at 2.5 GHz. Power dissipation is 6.6 mW maximum. Low channel-to-channel skew, 35ps max Packaging (Pb-free & Green): 32 TQFN (ZL) Application Routing of USB3.0 signals with low signal attenuation between source and sink.
