The FSUSB30 is a low-power, two-port, high-speed USB 2.0 switch. Configured as a double-pole double-throw (DPDT) switch, it is optimized for switching between two high-speed (480Mbps) sources or a Hi-Speed and Full-Speed (12Mbps) source. The FSUSB30 is compatible with the requirements of USB2.0 and features an extremely low on capacitance (C_ON) of 3.7pF. The wide bandwidth of this device (720MHz), exceeds the bandwidth needed to pass the third harmonic, resulting in signals with minimum edge and phase distortion. Superior channel-to-channel crosstalk minimizes interference.

The FSUSB30 contains special circuitry on the D+/D- pins which allows the device to withstand an overvoltage condition when powered off. This device is also designed to minimize current consumption even when the control voltage applied to the S pin, is lower than the supply voltage (V_CC). This feature is especially valuable to ultra-portable applications such as cell phones, allowing for direct interface with the general purpose I/Os of the baseband processor. Other applications include switching and connector sharing in portable cell phones, PDAs, digital cameras, printers, and notebook computers.
