FSA203 — Multimedia High-Speed USB, Video, and Negative Swing Audio Switch with Video Amp/Filter Features Description 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 and 2.5 x 4.5mm 20-Pin TSSOP 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.
