Functional Description
The FSA110 is a combined USB and audio switch that
enables sharing the D+/D- lines of a USB connector with
stereo audio CODEC outputs. The /OE pin has an
internal pull-up resistor, which results in a default USB
mode configuration. This configuration provides built-in
mute on the audio path during system power-up and in
default USB mode allows the system to transmit USB
data regardless of the switch VCC supply. This
configuration allows the user to override the USB default
state and send analog audio on the USB path when the
USB cable is connected. In such a configuration, there
is no need for auto USB detection. The audio switch
path is capable of handling negative signals, eliminating
the need for large coupling capacitors and greatly
reducing the potential for audio pop. Termination
resistors on the audio R, L ports are enabled when the
switch is in USB mode; which reduces the incidence of
audio pop when enabling the audio path.
