FSA203 — Multimedia High-Speed USB, Video, and
Negative Swing Audio Switch with Video Amp/Filter
Features
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.
USB: 3.5Ω Typical On Resistance
Video/Mic: 3Ω Typical On Resistance
Audio: 3.5Ω Typical On Resistance
USB: -3db Bandwidth at 0pF > 745MHz
Video: -3db Bandwidth > 615MHz
Video: 1.0db Flatness > 6MHz
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.
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.
Packaged in Pb-free 20-Lead DQFN and
2.5 x 4.5mm 20-Pin TSSOP
Typical applications involve switching in portables and
consumer applications, such as cell phones, digital
cameras, and notebooks with hubs or controllers.
Applications
Cell Phone, PDA, Digital Camera, and Notebook
LCD Monitor, TV, and Set-Top Box
