1.3. Application Overview

The following block diagram shows an example appli-

cation for the MAS 35x9F in a portable audio player

device. Besides a simple controller and the external

flash memories, all required components are inte-

grated in the MAS 35x9F. The MAS 35x9F supports

both speech and radio quality audio encoding, as well

as compressed-audio decoding tasks.

Fig. 1–1 depicts a portable power-optimized audio

application. The two embedded DC/DC converters of

the MAS 35x9F generate optimum power supply volt-

ages for the DSP core and also for state-of-the art

flash memories that typically require 2.7 to 3.3 V sup-

ply. The performance of the DC/DC converters

reaches efficiencies of up to 95%.
