FSA203 — Multimedia High-Speed USB, Video, and Negative Swing Audio Switch with Video Amp/Filter June 2007 FSA203 — Multimedia High-Speed USB, Video, and Negative Swing Audio Switch with Video Amp/Filter Features 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 Low-Power Shutdown Mode: 1µA Maximum Power-Off Protection on Common D+/R, D-/L, Video/Microphone Ports Packaged in Pb-free 20-Lead DQFN and 2.5 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 Cell Phone, PDA, Digital Camera, and Notebook LCD Monitor, TV, and Set-Top Box IMPORTANT NOTE: For additional performance information, please contact analogswitch@fairchildsemi.com.
