Audio Front-End
6.1 Main MIC, Receiver, Headset and OPamp stage.
The audio front-end essentially consists of voice and audio data paths. Figure 29 shows the block diagram of the audio front-
end. All voice band data paths comply with the GSM 03.50 specification. Mono hands-free audio or external FM radio
playback paths are also provided. The audio stereo path facilitates CD-quality playback, external FM radio, and voice
playback through a headset. In SDP100, The Voice in normal mode is output to AU_Out0_N/P and voice in Headset
Mode/Loud Mode is output to AU_MOUTL/R . The Melody in Normal mode/Headset Mode is output to AU_MOUTL/R.
The Mic input in normal mode/Loud mode is to AU_VIN0_N/P and Mic input in headset mode is to AU_VIN1_N/P.
The below tables are shown the PGA gains of Mic, Voice and Melody. And the S/W control gain can be changed in Debug
Mode using *#110*01#
