FSA3041: High-Speed 4:1 USB2.0 / Mobile High-Definition Link (MHL™) / Audio / UART Switch

The FSA3041 is a bi-directional, low-power, high-speed, 4:1, USB2.0, MHL™, UART, and audio switch. Configured as a Double-Pole, Four-Throw (DP4T) switch; it is optimized for switching between high- or full-speed USB, Mobile High-Definition Link sources (MHL Rev. 2.0 specification), UART, and negative-swing capable audio. In addition, either USB 2.0 path can be used as a UART path.

The FSA3041 contains circuitry on the switch I/O pins, for applications where the VCC supply is powered off (VCC = 0 V), that allows the device to withstand an over-voltage condition. This switch is designed to minimize current consumption even when the control voltage applied to the control pins is lower than the supply voltage (VCC). This is especially valuable in mobile applications, such as cell phones, allowing direct interface with the general-purpose I/Os of the baseband processor. Other applications include switching and connector sharing in portable cell phones, digital cameras, and notebook computers.
