35 / 66 page  Production Data WM9711L w PD Rev 4.1 April 2004 35 SPEAKER MIXER The speaker mixer drives the LOUT2 and ROUT2 output. The following signals can be mixed into the speaker path: • PHONE (controlled by register 0Ch, see “Audio Inputs”) • LINE_IN (controlled by register 10h, see “Audio Inputs”) • the stereo DAC signal (controlled by register 18h, see “Audio DACs”) • PC_BEEP (controlled by register 0Ah, see “Audio Inputs”) • the AUXDAC signal (controlled by register 12h, see “Auxiliary DAC”) In a typical smartphone application, the speaker signal is a mix of AUXDAC (for system alerts or ring tone playback), PHONE (for speakerphone function), and PC_BEEP (for externally generated ring tones). MONO MIXER The mono mixer drives the MONOOUT pin. The following signals can be mixed into MONOOUT: • LINE_IN (controlled by register 10h, see “Audio Inputs”) • the output of the Record PGA (see “Audio ADC”, “Record Gain”) • the stereo DAC signal (controlled by register 18h, see “Audio DACs”) • the MIC signal (controlled by register 10h, see “Audio Inputs”) • PC_BEEP (controlled by register 0Ah, see “Audio Inputs”) • the AUXDAC signal (controlled by register 12h, see “Auxiliary DAC”) In a typical smartphone application, the MONOOUT signal is a mix of the amplified microphone signal (possibly with Automatic Gain Control) and (if enabled) an audio playback signal from the stereo DAC or the auxiliary DAC. SIDE TONE CONTROL The side tone path is into the headphone mixer and is either from the MIC or ALC path (with no 20dB boost) REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION 15 STM 1 MIC side tone select 0: selected 1 : not selected (path muted) 14:12 STVOL 010 (0dB) MIC Sidetone volume 000 : +6dB (max.) 001: +3dB … (3dB steps) 111 : -15dB (min.) 11:10 ALCM 11 ALC side tone select 11: mute 10: mono – left 01: mono – right 00: stereo 14h Sidetone Control 9:7 ALCVOL 010 (0dB) ALC Sidetone volume Similar to STVOL Table 23 Side Tone Control |
