Description

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,

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

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.
