The FSA223 is a Double-Poe, Double Throw (DPDT) multiplexer that combines a low-distortion audio and a USB2.O High-Speed (HS) switch path. This configuration enables audio axis USB data to share a common connector port. The architecture is designed to allow both audio and USB signals to swing EEIOW ground. This means a common USB and headphone jack can be used for personal media players and portable peripheral devices. Since USB2.O is an industry standard for shared data- path in portable devices, the FSA223 also incorporates a Vcc detection capability. The FSA223 includes a power-off feature to minimize current consumption when Vcc is not present. This power-off circuitry is available for the common D+/R, D-/L ports only. Typical applications involve switching in portables and consumer applications, such as cell phones, digital cameras, and notebooks “the hubs or controllers.
