PI3USB304 3.3V USB 3.0 SuperSpeed Dual 2:1 Mux/DeMux Switch with Enable Features Description • • • • • • • • • • • • • Pericom Semiconductor’s PI3USB304 is a dual USB 3.0 2:1 switch. It can switch transmit and receive differential signals for two 5 Gbps SuperSpeed USB 3.0 lanes. Using advanced high-speed transmission gate technology, PI3USB304 is bidirectional and offers both excellent signal integrity and very low power. -3 dB bandwidth is 8.2 GHz. Insertion loss is extremely low, only 1 dB at 2.5 GHz. All other ac parameters – return loss, crosstalk, off isolation – lead the industry in performance. Power dissipation is very small -- 0.5 mW typical (0.15 mA @ 3.3V) Dual 2:1 USB 3.0 Switch Bi-directional Operation 5 Gbps Performance Very high -3 dB bandwidth: 8.2 GHz Low Insertion Loss: -1dB @ 2.5 GHz Excellent Return Loss: -29 dB @ 2.5 GHz Low Crosstalk: -37 dB @ 2.5 GHz Low Off Isolation: -25 dB @ 2.5 GHz Low Bit-to-Bit Skew, 10 ps max Low Channel-to-Channel Skew, 20 ps max Supply Voltage 3.3V Low power dissipation: 0.5 mW typ. Packaging (Pb-free & Green): – 42-contact, TQFN (ZH42) Application Routing USB 3.0 SuperSpeed signals.
