LINE_IN_R
24
I
Right Line Input. The right line-level may be selected for recording via one of the stereo ADC’s via
the Input Mux. In addition, this input can be gained/attenuated from +12dB to -34.5dB in 1.5dB
steps and then summed with right line output (LINE_OUT_R).
CD_L
18
I
Left CD Audio Channel. This line-level input may be input to one of the stereo ADC’s via the Input
Mux. It can also be gained/attenuated from +12dB to -34.5dB in 1.5dB steps and then summed with
the Left Line Output (LINE_OUT_L).
CD_GND
19
I
CD Audio Analog Ground.
CD_R
20
I
Right CD Audio Channel. This line-level input is selected for input to one of the stereo ADCs via the
Input Mux. It can also be gained/attenuated from +12dB to -34.5dB in 1.5dB steps and then
summed with the Right Line Output (LINE_OUT_R).
VIDEO_L
16
I
Left Video Input. This line-level input is driven with the left channel audio track from a video source.
The signal is selected for input to one of the stereo ADCs via the Input Mux, and it can be gained/at-
tenuated from +12dB to -34.5dB in 1.5dB steps and then summed with Left Line Output
(LINE_OUT_L).
VIDEO_R
17
I
Right Video Input. This line-level input is driven with the right channel audio track from a video
source. The signal is selected for input to one of the stereo ADCs via the Input Mux, and it can be
gained/attenuated from +12dB to -34.5dB in 1.5dB steps and then summed with Right Line Output
(LINE_OUT_R).
AUX_L
14
I
Left Auxiliary Input. This line-level input is input to one of the stereo ADCs via the Input Mux. It can
also be gained/attenuated from +12dB to -34.5dB in 1.5dB steps and then summed with the Left
Line Output (LINE_OUT_L).
AUX_R
15
I
Right Auxiliary Input. This line-level input is input to one of the stereo ADCs via the Input Mux. It
can also be gained/attenuated from +12dB to -34.5dB in 1.5dB steps and then summed with the
Right Line Output (LINE_OUT_R).
LINE_OUT_L
35
O
Left Line Output. This line level output is the post-mixed output for the left audio channel. The audio out-
put passes through a Master Volume block that provides attenuation from 0dB to 45dB in 1.5dB steps.
LINE_OUT_R
36
O
Right Line Output. This line level output is the post-mixed output for the right audio channel. The
audio output passes through a Master Volume block that provides attenuation from 0dB to 45dB in
1.5dB steps.
MONO_OUT
37
O
Mono Output. This user selectable line level output is either the post-mixed output or the micro-
phone input. The mono output passes through a Mono Volume block that provides attenuation from
0dB to 45dB in 1.5dB steps.

REFOUT
27
O
Voltage Reference. Nominal 2.25V reference output. Should not be used to sink or source current.
28
O
Voltage Reference Out. Nominal 2.25V reference output with 5mA drive capability. Intended a
microphone bias.
AFILT1
29
O
Anti-Alias Filter 1 (Left Record Channel). This pin requires a 1nF capacitor to analog ground for
proper operation.
AFILT2
30
O
Anti-Alias Filter 2 (Right Record Channel). This pin requires a 1nF capacitor to analog ground for
proper operation.
AFILT3
31
O
Anti-Alias Filter 3 (MIC Record Channel). This pin requires a 1nF capacitor to analog ground for
proper operation.
CAP1, CAP2
33, 34
O
Left Channel DC Blocking CAP For proper operation connect a 1
μ
F capacitor between these two pins.
Right Channel DC Blocking CAP. For proper operation connect a 1
μ
F capacitor between these
two pins.
CAP3, CAP4
39, 40
O
XTL_IN
2
I
24.576MHz Crystal Input. Leave this pin unconnected when using an external clock source.
XTL_OUT
3
