Functional Description
PC_BEEP
12
I
This is a mono input which gets summed into the stereo line output after the National 3D
Sound block. The PC_BEEP level can be adjusted from 0dB to 45dB in 3dB steps, or
muted, via register 0Ah.
PHONE
13
I
This is a mono input which gets summed into the stereo line output after the National 3D
Sound block. The PHONE level can be adjusted from +12dB to 34.5dB in 1.5dB steps as
well as muted via register 0Ch.
CD_L
18
I
This line level input can be routed through the input mux and recorded by the left ADC. In
addition, this analog input gets summed into the left output stream. The amount of CD_L
signal mixed in the left output stream can be adjusted from +12dB to 34.5dB in 1.5dB steps
as well as muted via register 12h.
CD_GND
19
I
This input can be used to reject common mode signals on the CD_L and CD_R inputs.
CD_GND is an AC ground point and not a DC ground point. This input must be AC-coupled
to the source signal’s ground.
