FSA321 Description
The FSA321 is a Double-Pole, Double Throw (DPDT) multiplexer that bines a low-distortion audio and a USB2.0 High-Speed (HS) switch path. This configuration enables audio and USB data to share a mon connector port. The architecture is designed to allow audio signals to swing below ground.
