Description
The FSA321 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
audio 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, FSA321 can be configured for
automatic VBUS detection. The FSA321 includes a
power-off feature as well as over-voltage tolerance to
minimize current consumption when VSW exceeds VCC.
Typical applications involve switching in portables and
consumer applications, such as cell phones, digital
cameras, and notebooks with hubs or controllers.
Applications
ƒ MP3, Cell Phone, PDA, Digital Camera, and
Notebook
ƒ LCD Monitor, TV, and Set-Top Box
