  • The FSUSB43 is a bi-directional, low-power, two-port, high-speed, USB2.0 switch. Configured as a double-pole, double-throw switch (DPDT) switch, it is optimized for switching between two Hi-Speed (480Mbps) sources or a Hi-Speed and Full-Speed (12Mbps) source. The FSUSB43 is compatible with the requirements of USB2.0 and features an extremely low on capacitance (CON) 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 also minimizes interference. The FSUSB43 contains special circuitry on the switch I/O pins for applications where the VCC supply is powered-off (VCC=0), which allows the device to withstand an over-voltage condition. This minimizes current consumption even when the control voltage applied to the SEL pin is lower than the supply voltage (VCC). This feature is especially valuable to mobile 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.
