PI3USB304 3.3V USB 3.0 SuperSpeed Dual 2:1 Mux/DeMux Switch with Enable Features Description Dual 2:1 USB 3.0 Switch Pericom Semiconductor s PI3USB304 is a dual USB 3.0 2:1 switch. It can switch transmit and receive differential signals for Bi-directional Operation two 5 Gbps SuperSpeed USB 3.0 lanes. 5 Gbps Performance Using advanced high-speed transmission gate technology, Very high -3 dB bandwidth: 8.2 GHz PI3USB304 is bidirectional and offers both excellent signal Low Insertion Loss: -1dB 2.5 GHz integrity and very low power. Excellent Return Loss: -29 dB 2.5 GHz -3 dB bandwidth is 8.2 GHz. Insertion loss is extremely low, only Low Crosstalk: -37 dB 2.5 GHz 1 dB at 2.5 GHz. All other ac parameters return loss, crosstalk, Low Off Isolation: -25 dB 2.5 GHz off isolation lead the industry in performance. Power dissipation Low Bit-to-Bit Skew, 10 ps max is very small -- 0.5 mW typical (0.15 mA 3.3V) Low Channel-to-Channel Skew, 20 ps max Supply Voltage 3.3V Application Low power dissipation: 0.5 mW typ. Routing USB 3.0 SuperSpeed signals.
