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 V
power-off feature to minimize current consumption when

for the common D+/R, D-/L ports only. Typical
applications
consumer applications, such as cell phones, digital
cameras, and notebooks with hubs or controllers.

... Functional Description The FSA201 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 full-speed USB signals and includes an automatic V -detection circuit. When a USB connector, rather BUS than a headphone, is connected to the ultra-portable device the switch is automatically configured for full- speed USB data transfer ...
