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
Mode Control Register (Index 5Eh)
. The bit config-
uration for each detailed mode is listed in Table 1
on page 17.
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.
