


USB: 3.5Ω Typical On Resistance
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.

Packaged in Pb-free 20-Lead DQFN
Video/Mic: 3Ω Typical On Resistance
Audio: 3.5Ω Typical On Resistance
USB: -3db Bandwidth at 0pF > 745MHz
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.
Video: -3db Bandwidth > 615MHz
Video: 1.0db Flatness > 6MHz
Low-Power Shutdown Mode: 1µA Maximum
Power-Off Protection on Common D+/R, D-/L,
Video/Microphone Ports
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.
Applications


Cell Phone, PDA, Digital Camera, and Notebook
LCD Monitor, TV, and Set-Top Box
Typical applications involve switching in portables and
consumer applications, such as cell phones, digital
cameras, and notebooks with hubs or controllers.

Pin Assignments
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
