High-Speed USB2.0/Mobile High-Definition Link (MHL™) with Negative Swing Audio

The FSA3230 is a bi-directional, low-power, high-speed, 3:1, USB2.0, MHL™ and audio switch. Configured as a double-pole, triple-throw (DP3T) switch, it is optimized for switching between high- or full-speed USB, Mobile High-Definition Link sources (per MHL Rev. 2.0 specification) and negative swing capable audio. A Single-Pole, Double-Throw (SPDT) switch is provided for ID. This ID switch provides path to support On-The-Go (OTG) communication for the USB Path OR CBUS for the MHL Path. The FSA3230 contains special circuitry on the switch I/O pins, for applications where the VCC supply is powered off (VCC=0), 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.
