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

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.

Features

  • 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.
  • Automatically Detects Vbus for Switch Path Selection.
