FSA321 - USB2.0 Hi-Speed (480Mbps) and Audio Switches

Description

The FSA321 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

Audio: 1.8 Typical On Resistance.
HS-USB: 8 Typical On Resistance.
HS-USB: 5pF Typical On Capacitance.
USB Path -3db Bandwidth: > 720MHz.
Negative Swing Capable Audio Channel.
Power-off Protection on Common D+/R, D-/L Ports.
Automatic USB Detection (Configurable).
OVT on all I/O Ports.
Flow-Through Pin Out Eliminates PCB Vias.
Built-In Termination on Unselected Audio Paths to Inhibit Audio Pop.
