Audio Interface
The audio solution on the ReadyBoard 620 is provided by the (Southbridge) I/O Hub (CS5536) and the on-
board Audio CODEC (ALC203). These two chips use a digital interface to communicate between the two,
which is defined by AC’97 and is revision 2.3 compliant. The input or output signals for the audio interface
go through the 16-pin connector (J15) to an external cable and/or board, which has the respective audio
connections. The PC Beep Speaker signal from the I/O Hub is also fed to the on board Audio CODEC to
provide a PC Beep signal for the stereo line out connections.
