31 / 98 page  Product Preview WM8593 w PP Rev 1.0 January 2007 31 DE-EMPHASIS A digital de-emphasis filter may be applied to the DAC outputs when the sampling frequency is 44.1kHz. The de-emphasis filter for each DAC can be applied independently. The deemphasis filter responses and error can be seen in Figure 67 and Figure 68. REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION R2 DAC1_CTRL1 02h 6 DAC1 _DEEMPH 0 DAC1 De-emphasis 0 = No de-emphasis 1 = Apply 44.1kHz de-emphasis R7 DAC2_CTRL1 07h 6 DAC2 _DEEMPH 0 DAC2 De-emphasis 0 = No de-emphasis 1 = Apply 44.1kHz de-emphasis Table 20 De-emphasis Control ADC FEATURES The WM8593 features a stereo 24-bit sigma-delta ADC, digital volume control with zero cross, a selectable high pass filter to remove DC offsets, and support for both master and slave clocking modes. REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION R13 ADC_CTRL1 0Dh 6 ADC_EN 0 ADC Enable 0 = ADC disabled 1 = ADC enabled Table 21 ADC Enable Control DIGITAL VOLUME CONTROL The ADC digital volume can be adjusted between +30dB and -97dB in 0.5dB steps. Left and right channels can be controlled independently. Volume changes can be applied immediately to each channel, or volume changes can be written to both channels before writing to an update bit in order to change the volume in both channels simultaneously. Volume control includes optional zero cross functionality. When zero cross is enabled, volume changes are not applied until the output level crosses the DC level of the ADC output. Zero cross helps to prevent pop and click noise when changing volume settings. REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION R16 ADCL_VOL 10h 7:0 ADCL _VOL[7:0] 11000011 R17 ADCR_VOL 11h 7:0 ADCR _VOL[7:0] 11000011 ADC Digital Volume 0000 0000 = Digital mute 0000 0001 = -97dB 0000 0010 = -96.5dB …0.5dB steps 1100 0011 = 0dB …0.5dB steps 1111 1110 = +29.5dB 1111 1111 = +30dB R16 ADCL_VOL 10h 8 ADCL_VU 0 R17 ADCR_VOL 11h 8 ADCR_VU 0 ADC Digital Volume Update 0 = Latch ADC volume setting into Register Map but do not update volume 1 = Latch ADC volume setting into Register Map and update left and right channels simultaneously |
