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 V_avor V_busis 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
