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,
for applications where the V_CC supply is powered off
(V_CC = 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 (V_CC). 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.
