3. DIGITAL SIGNAL PATHS
The CS4205 includes a number of internal digital
signal path options. Figure 9 shows the principal
signal flow options through one channel of the de-
vice. Four commonly used signal flow modes are
detailed in the following sections. The signal flow
modes are controlled through the bits in the AC
uration for each detailed mode is listed in Table 1
3.1
Analog Centric Mode
Analog centric mode is detailed in Figure 10 on
page 18. In this mode, all the digital sources are
pre-mixed in the digital mixer and sent to the
DACs. The DAC outputs are mixed with the analog
sources in the analog mixer. The ADCs send cap-
tured data directly to the host. The ADC mux is
used to select a single source or the output of the in-
put mixer for capture. In the analog centric mode,
effects processing is only available on digital
sources.
