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 data-
path 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.
