FSA201 USB2.0 Full-Speed and Audio Switches with Negative Signal Capability Features 3Ω Typical ON Resistance -3db Bandwidth: > 250MHz Low Power Consumption Packaged in Pb-free 10-Lead MicroPak™ (1.6 x 2.1mm), 10-pin MSOP (Preliminary) Power-off Protection on Common D+/R, D-/L Ports Automatically Detects Vbus for Switch Path Selection Applications Cell Phone, PDA, Digital Camera, and Notebook LCD Monitor, TV, and Set-top Box Description The FSA201 is a Double-Pole, Double Throw (DPDT) multiplexer that combines a low-distortion audio and a USB2.0 Full-Speed (FS) 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 FSA201 also incorporates a Vbus detection capability. The FSA201 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.
