onsemi FSUSB43L10X

The FSUSB43 is a bi−directional, low−power, two−port, high−speed, USB2.0 switch. Configured as a double−pole, double−throw (DPDT) switch, it is optimized for switching between two high−speed (480 Mbps) sources or a high−speed and full−speed (12 Mbps) source. The FSUSB43 is compatible with the requirements of USB2.0 and features an extremely low on capacitance (C_ON) of 5.7 pF. The wide bandwidth of this device (720 MHz) 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 V_CC supply is powered−off (V_CC = 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 (V_CC). 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.
