23 / 56 page  WM8731 Advanced Information WOLFSON MICROELECTRONICS LTD AI Rev 2.0 February 2001 23 ADC FILTERS The ADC filters perform true 24 bit signal processing to convert the raw multi-bit oversampled data from the ADC to the correct sampling frequency to be output on the digital audio interface. Figure 15 illustrates the digital filter path. FROM ADC DIGITAL HPF DIGITAL DECIMATION FILTER TO DIGITAL AUDIO INTERFACE DIGITAL DECIMATOR HPFEN Figure 15 ADC Digital Filter The ADC digital filters contain a digital high pass filter, selectable via software control. The high-pass filter response detailed in Digital Filter Characteristics. The software control is shown in Table 5. REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION 0000101 Digital Audio Path Control 0 ADCHPD 0 ADC High Pass Filter Enable (Digital) 1 = Enable High Pass Filter 0 = Disable High Pass Filter Table 5 ADC Software Control There are several types of ADC filters, frequency and phase responses of these are shown in Digital Filter Characteristics. The filter types are automatically configured depending on the sample rate chosen. Refer to the sample rate section for more details. DAC FILTERS The DAC filters perform true 24 bit signal processing to convert the incoming digital audio data from the digital audio interface at the specified sample rate to multi-bit oversampled data for processing by the analogue DAC. Figure 16 illustrates the DAC digital filter path. FROM DIGITAL AUDIO INTERFACE MUTE DIGITAL INTERPOLATION FILTER TO LINE OUTPUTS DIGITAL DE_EMPHASIS DEEMP DACMU Figure 16 DAC Filter Schematic |
