39 / 156 page  ALC5642-VF Datasheet Multi-Channel Audio Hub/CODEC with embedded Voice DSP and SounzReal TM Digital Sound Effect 27 Rev. 0.93 7.6.3. Mixers The ALC5642 has digital and analog mixers build-in. Output mixer - OUTMIXL/R The stereo analog mixer can do mixing for DAC output and analog input. The mixer output is mainly for headphone output and line output. Each input path has it’s mute control to the mixer block in MX-4D ~ MX-52. pow_outmixl and pow_outmixr can be used to power on/off OUTMIXL/R Speaker mixer – SPKMIXL/R The stereo analog mixer can do mixing for OUTMIX output, DAC output and analog input. The mixer output is for speaker output. Each input path has it’s mute control to the mixer block in MX-46 and MX-47. pow_spkmixl and pow_spkmixr can be used to power on/off SPKMIXL/R. Speaker_Out mixer – SPOMIXL/R The stereo analog mixer can do mixing for from speaker volume, DAC and analog input. The mixer output is direct to speaker output. E ach input path has it’s mute control to the mixer block in MX-48 and MX-49. LINE_Out mixer – LOUTMIX The stereo analog mixer can do mixing for analog input and DAC output. The mixer output is for line-out output for drive external amplifier. Each input has individual mute control to the mixer block in MX-53. pow_lout can be used to power on/off LOUTMIX. Record mixer – RECMIXL/R The stereo analog mixer can do mixing for analog input and OUTMIX output. The mixer output is for ADC input. Each input path has it ’s mute control to the mixer block in MX-3B ~ MX-3E. pow_recmixl and pow_recmixr can be used to power on/off RECMIXL/R. HP mixer – HPOMIXL/R The stereo analog mixer can do mixing for headphone volume and DAC output. The mixer output directly output to external headphone device. Each input path has it’s mute control to the mixer block in MX-45. Digital mixer There are ten digital mixers in ALC5642. Four digital mixers are assigned for ADC recording. These four mixers can mix analog line input, analog microphone input and digital microphone input then output to I2S interface to other device. Another four digital mixers are assigned DAC playback. These mixers can mix digital data from I2S interface or ADC data from external analog signal. The mixed data is output to analog DAC and output port to drive external device. The other two mixers are use for DA-AD processing. The incoming data from two I2S interfaces (DACDAT) uses these two mixers to do mixing and output to I2S interface (ADCDAT). |
