FSA3200: Two-Port, High-Speed USB2.0 Switch with Mobile High-Definition Link

The FSA3200 is a bi-directional, low-power, two-port, high-speed, USB2.0 and video data switch. Configured as a double-pole, double-throw (DPDT) switch for data and a single-pole, double-throw (SPDT) switch for ID; it is optimized for switching between high- or full-speed USB and Mobile Digital Video sources (MDV), including supporting the MHL™ Rev. 1.0 specification.

The FSA3200 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 feature is especially valuable to 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.
