Description
The FSA203 is a multimedia device that includes a
Double-Pole, Double Throw (DPDT) USB / audio
multiplexer, a video/microphone switch, and a video
amplifier / filter path. The DPDT path combines a low-
distortion audio and a USB2.0 switch path.
This configuration enables audio and USB data to share
a common connector port. The architecture is designed
such that audio signals are allowed to swing below
ground, enabling the use of a common USB and
headphone connector for personal media players and
similar portable peripheral devices.
The FSA203 includes a power-off feature to minimize
current consumption when V
av
or V
bus
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.
