FSA221 — USB2.0 High-Speed (480Mbps) and

Audio Switches with Negative Signal Capability

Features

Description

The FSA221 is a Double-Pole, Double Throw (DPDT)

multiplexer that combines a low-distortion audio and a

USB2.0 High-Speed (HS) switch path. This

configuration enables audio and USB data to share a

common connector port. The architecture is designed to

allow audio signals to swing below ground. This means

a common USB and headphone jack can be used for

personal media players and portable peripheral devices.

HS-USB: 4Ω Typical On Resistance

HS-USB: 4.5pF Typical On Capacitance

Audio: 3Ω Typical On Resistance

-3db Bandwidth: > 720MHz

Low Power Consumption

Power-off Protection on Common D+/R, D-/L Ports

Since USB2.0 is an industry standard for shared data-

path in portable devices, the FSA221 also incorporates

a V_busdetection capability. The FSA221 includes a

power-off feature to minimize current consumption when

V_busis 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.
