Description
The FSA221 is a Double-Pole, Double Throw (DPDT) multiplexer that combines a low-distortion audio and a USB2.0 High-Speed (HS) switch path. This configuration enables audio and USB data to share a common connector port. The architecture is designed to allow audio signals to swing below ground. This means a common USB and headphone jack can be used for personal media players and similar portable peripheral devices. Since USB2.0 is an industry standard for shared data- path in portable devices, the FSA221 also incorporates a V bus 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 common 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.

- A Sel - Internal resistor to GND provides auto-Vbus detect if there is no external connection. Forcing ASel HIGH
when VAUDIO is present overrides the USB path even if Vbus is present.
- H - Value is the threshold as defined to meet USB2.0 V bus requirements and audio supply threshold in a system
eliminates the need for large coupling capacitors. Figure 5. FSA221 Typical Application Diagram
