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.
