FSA221 USB2.0 High-Speed (480Mbps) and Audio Switches with Negative Signal Capability Features Description HS-USB: 4Ω Typical On Resistance 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. Power-off Protection on Common D+/R, D-/L Ports D+/R, D-/L Ports: 8pf Typical On Capacitance Audio: 3Ω Typical On Resistance -3db Bandwidth: > 720MHz Low Power Consumption Packaged in Pb-free 10-Lead MicroPak™ (1.6 x 2.1mm), 10-pin MSOP (Preliminary) 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.

The ASel pin is internally terminated by a resistor to GND (typical value 3MΩ) 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 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. 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. 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 Application Diagram Vbus 3.0V– 3.6V Vaudio USB 2.0 - USB FS Source 5V D+/R Vbus Rpd D+ GND R D- Audio CODEC ASel Switch Select Control Circuitry L D-/L USB Mini-AB Connector ID FSA201 GND Figure 5. © 2006 Fairchild Semiconductor Corporation FSA221 Rev. 1.0.3 FSA221 Typical Application Diagram www.fairchildsemi.com 3 FSA221 USB2.0 High-Speed and Audio Switches with Negative Signal Capability Functional Description The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed.
