PI3USB102 Datasheet | Pericom Semiconductor

PI3USB102 USB 2.0 High-Speed (480 Mbps) Signal Switch Targeted for Battery Powered Applications Features - USB 2.0 pliant (high speed and full speed) - RON is 5.5Ω typical @ VCC = 3.0V - Low bit-to-bit skew - Low Crosstalk: - 35dB @ 480 Mbps - Off Isolation: - 40dB @ 480 Mbps - Near-Zero propagation delay: 250ps - Switching speed: 9ns - Channel On Capacitance: 5.5pF - VCC Operating Range: 2.7V to 4.2V ±10% - Data pin I/O ESD: 8kV contact - 1,000 MHz Bandwidth - I/O pins have over-voltage protection and can tolerate a short to Vbus - Packaging (Pb-free & Green): 10-contact TQFN (ZL10) Description The PI3USB102 is a single differential channel 2:1 multiplexer/ demultiplexer USB 2.0 Switch. Industry leading advantages include a propagation delay of less than 250ps, resulting from its low channel resistance and I/O capacitance. The device multiplexes differential outputs from a USB Host device to one of two corresponding outputs. The switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. It is designed for low bit-to-bit skew, high channel-to-channel noise isolation and is patible with various standards, such as High Speed USB 2.0 (480 Mb/s). The PI3USB102 offers overvoltage protection per the USB 2.0 specification. With the chip powered on or off, all I/O pins can withstand a short to Vbus (5V +/-10%). This feature can only be offered if a 100-ohm pull up resistor is placed between VCC pin to the power supply.
