Description of the audioprocessor
4.1
Input stages
One quasi-differential stereo input, one full-differential stereo input and maximum five
single-ended inputs are available.
4.1.1
Quasi-differential stereo input (QD1)
The QD input is implemented as a buffered quasi-differential stereo stage with 100 k
Ω input-
impedance at each input. There is -3 dB attenuation at QD input stage.
4.1.2
Single-ended stereo input (SE1, SE2, SE3)
The input-impedance at each input is 100 k
Ω and the attenuation is fixed to -3 dB for
incoming signals.
4.1.3
Full-differential stereo input or single-ended input (FD1/QD2/SE4+SE5)
This device provides a full-differential stereo input stage (FD1) or 2nd quasi-differential
stereo input stage. The full differential is a buffered full-differential stereo stage with 100 k
Ω
input-impedance at each input. When using as QD2 application, it needs to connect the two
QD2G pins together from external and the input impedance at QDG becomes 50 k
Ω. This
stage can be also configured as 2 single-ended stereo input stages (SE4 and SE5). The
configuration is done with the input selector control bits and the selection of FD1 and QD2 is
controlled by a separate bit. There is -3 dB attenuation at the input stage. Figure 3 shows
the block diagram of this input stage.
