FSA223

FSA223 — USB2.0 High-Speed (480Mbps) and Audio Switches with Negative Signal Capability December 2008 FSA223 — USB2.0 High-Speed (480Mbps) and Audio Switches with Negative Signal Capability Features HS-USB: 4Ω Typical On Resistance HS-USB: 4.5pF Typical On Capacitance Audio: 3Ω Typical On Resistance -3db Bandwidth: > 720MHz Low Power Consumption Power-off Protection on Common D+/R, D-/L Ports Automatically Detects VCC for Switch Path Selection Description The FSA223 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 both audio and USB signals to swing below ground. This means a common 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 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 with hubs or controllers. Applications Cell Phone, PDA, Digital Camera, and Notebook LCD Monitor, TV, and Set-Top Box Related Resources Please refer to tape and reel specifications on www.fairchildsemi.com; http://www.fairchildsemi.com/packaging.
