3.12 Audio Front-End

Figure 3.12.1 Audio Section Overview

3.12.1 Functional Overview

The audio front-end of X-GOLD™213 offers the digital and analog circuit blocks for both receive and transmit

audio operation, from a mobile phone perspective (called audio-in and audio-out subsequently). It features a

high-quality, stereo digital-to-analog path with amplifier stages for connecting acoustic transducers to X-

GOLD™213. In audio-in path the supply voltage generation for electret microphones, a low-noise amplifier

and analog to digital conversion are integrated in X-GOLD™213. A more detailed functional description will

be given in the following sections.

The audio front-end itself can be considered to be organized in three sub-blocks:

• Interface to processor cores (TEAKLite® and - indirectly - ARM)

• Digital filters

• Analog part

The following figure shows an architecture overview of the Audio section.
