Description
The FSA221 is a Double-Pole, Double Throw (DPDT) multiplexer that bines a low-distortion audio and a USB2.0 High-Speed (HS) switch path. This configuration enables audio and USB data to share a mon connector port. The architecture is designed to allow audio signals to swing below ground. This means a mon USB and headphone jack can be used for personal media players and portable peripheral devices.
Since USB2.0 is an industry standard for shared datapath in portable devices, the FSA221 also incorporates a Vbus detection capability. The FSA221 includes a power-off feature to minimize current consumption when Vbus is not present. This power-off circuitry is available for the mon D+/R, D-/L ports only. Typical applications involve switching in portables and consumer applications, such as cell phones, digital cameras, and notebooks with hubs or controllers.
