31 / 156 page  ALC5642-VF Datasheet Multi-Channel Audio Hub/CODEC with embedded Voice DSP and SounzReal TM Digital Sound Effect 19 Rev. 0.93 For ASRC function on Codec master mode, the Codec only support it on some conditions. These conditions are sample rate fix at 48KHz, MCLK fix at 19.2MHz and frame rate fix at 50FS. Some registers need to set for this mode as shown at Table 13. Table 13. Register Settings for ASRC Function on Master Mode Condition: Codec as Master Mode MCLK = 19.2MHz Frame Rate = 50*FS Target Sample Rate (FS) = 48KHz Item Register Settings Note I2S-1 to DAC1 MX-83 = 0x8000 ’h MX-84 = 0x0020 ’h MX-FB = 0x0004 ’h For DAC1 playback ASRC settings I2S-2 to DAC2 MX-83 = 0x1800 ’h MX-84 = 0xC000 ’h MX-FB = 0x0002 ’h For DAC2 playback ASRC settings AMIC to Stereo ADC Filter to I2S-1 MX-83 = 0x8000 ’h MX-84 = 0x0800 ’h MX-FB = 0x0004 ’h For AMIC to Stereo ADC Filter record ASRC settings AMIC to Mono ADC Filter to I2S-2 MX-83 = 0x1800 ’h MX-84 = 0x3800 ’h MX-FA = 0x0731 ’h MX-FB = 0x0002 ’h For AMIC to Mono ADC Filter record ASRC settings DMIC1 to Stereo ADC Filter to I2S-1 MX-83 = 0x8200 ’h MX-FB = 0x0004 ’h For DMIC1 to Stereo ADC Filter record ASRC settings DMIC2 to Mono ADC Filter to I2S-2 MX-83 = 0x1900 ’h MX-84 = 0x3800 ’h MX-FA = 0x0741 ’h MX-FB = 0x0002 ’h For DMIC2 to Mono ADC Filter record ASRC settings |
