2.5.3. Audio Output Interface

The audio output interface of the MAS 3506D is a

standard serial audio interface. The interface is config-

urable by software to work in 16-bit/sample and 32-bit/

sample mode. The default setup is a 16-bit mode

which is also the default setting for the DRD 3515A.

The 32-bit/sample mode is provided for high-resolution

D/A converters that expect more than 16-bit/sample

input data. The embedded D/A-converter of the

DRD 3515A is also capable of decoding the 32-bit/

sample format and provides a slightly better S/N per-

formance in this mode1). The audio output interface

timing is shown in Figure 2–6 and Figure 2–7.

1) If the 32-bit mode is selected and the D/A converter

of the DRD 3515A is still connected, it also has to

be switched to 32-bit I2S mode.
