Functional Description
The FSA321 is a combined USB and audio switch that
enables sharing the D+/D- lines of a USB connector with
stereo audio CODEC outputs. The USB Sel pin has an
internal pull-down resistor that results in a default audio-
mode configuration. The switch can be configured for
auto USB detection by connecting the VBUS pin to the
USB Sel pin. The audio switch path also handles
negative signals, eliminating the need for large coupling
capacitors and greatly reducing the potential for audio
pop. Termination resistors on the audio R and L ports
are enabled when the switch is in USB mode, this also
helps reduce audio pop when enabling the audio path.
The FSA321 allows for an audio override state by
forcing A/LP Sel high when USB Sel is high. This is
useful for USB car kit applications or if the device is in a
cradle charger
when “Send/End” is pressed.
