Audio Interface (J19)
The audio solution on the ReadyBoard 700 is provided by the Southbridge (VT82C686B) and the ion
board Audio CODEC (VT1612A). These two chips communicate through a digital interface, defined
by and compliant with AC’97 Rev 2.2. Input or output signals for the audio interface go through the 16-
pin connector (J19) to an external cable and/or board, which has the respective audio connections. The
PC-Beep Speaker signal from the Southbridge is also fed to the on board Audio CODEC to provide a
PC-beep signal for the stereo line out connections.
