FSA3000: Two-Port, High-Speed, MHL Switch

The FSA3000 is a bi-directional, low-power, two-port, high-speed, USB2.0 and video data switch that supports the Mobile High-Definition Link (MHL) Specification Rev. 1.0. Configured as a double-pole, double-throw (DPDT) switch for data, FSA3000 is optimized for USB2.0 and MHL data sources.

The FSA3000 contains circuitry on the switch I/O pins that allows the device to withstand an over-voltage condition in applications where the VCC supply is powered off (VCC=0). The FSA3000 minimizes current consumption even when the voltage applied to the control pins is lower than the supply voltage (VCC). This feature 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.
