5 x 4.
5mm 20-Pin TSSOP 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 lowdistortion 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 Vav or 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.
Applications ƒ ƒ Cell Phone, PDA, Digital Camera, and Notebook LCD Monitor, TV, and Set-Top Box www.
