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 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 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.

Notes: 1. ASel - 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. 2. H - Value is the threshold as defined to meet USB2.0 Vbus requirements and audio supply threshold in a system (see DC Tables).

FSA221 USB2.0 High-Speed and Audio Switches with Negative Signal Capability
Functional Description
The FSA221 is a combined USB and audio switch that enables sharing the D+/D- lines of a USB connector with stereo audio CODEC outputs. The switch is optimized for high-speed USB signals and includes an automatic Vbus-detection circuit. When a USB connector, rather than a headphone, is connected to the ultra-portable device the switch is automatically configured for highspeed USB data transfer. If no Vbus is detected, and yet VAUDIO is present, the switch is configured for the lowdistortion audio switch path. The audio switch path also handles negative signals (down to -2V), which eliminates the need for large coupling capacitors. For those applications where the Vbus is generated as a self-powered device or where Vbus is not removed, the ASel pin provides the ability to switch, under software control, to the audio path. The ASel pin is internally terminated by a resistor to GND (typical value 3M) and requires no connection for the standard ultra-portable (cell-phone, MP3, or portable media player). In an application where the supply to the FSA221 Vbus pin is not guaranteed to be removed, a GPIO pin can be used to switch out of high-speed USB mode into audio mode, using the ASel pin. The FSA221 Vbus pin must be connected directly to Vbus or a supply > 3.8V, not an LDO regulated down to 3.6V or a Vbat-generated supply that may fall below 3.8V in normal operation.

Absolute Maximum Ratings
The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The "Recommended Operating Conditions" table defines the conditions for actual device operation.
