ALC5620 datasheet i 2 c + i 2 s audio codec + voice pcm interface 19 track id: jatr-1076-21 rev. 1.0 7.8. analog audio output data path the ALC5620 supports three an alog audio output paths: ? spk_out_l/r ? hp_out_l/r ? mono_out 7.8.1. speaker output spk_out_l/r provides two-channel differential output. the spk_out_l source is set in reg1c [15:14]. sources are shown below: ? vmid ? headphone left mixer ? speaker mixer ? mono mixer the spk_out_r source is set in reg1c [12:11]. sources are shown below: ? vmid ? headphone right mixer ? speaker mixer ? mono mixer the ALC5620 speaker supports class ab and class d type amplifiers (set in reg1c[13]:spk_out_sel). as the voltage of spkvdd is usually higher than avdd, the driver should set the class ab vmid ratio in reg40[5:3], and the class d vmid ratio in re g40[7:6] in order to extend the output level. in class ab mode, for l+r mono speaker solutions, spk_out_r can select a di fferent signal source (spkr volume output or spkl volume output by reg1c[14]) but spk_out_rn only outputs spkr volume negative output. the spk_out_l/r volume and mu te are controlled by reg02. reg3e[13]: pow_spk_r and reg3e[12]:pow_spk_rn can be used to power down spk output. reg3c[14]: pow_clsab is used to power down class ab output, and index 46[15:12] is used to power down each output channel of class d. spk_out_l/r supports the zero-cross detect f unction (enabled at re g02[6][14]: sp_l_dezero/ sp_r_dezero). www.datasheet.co.kr datasheet pdf - http://www..net/

ALC5620 datasheet i 2 c + i 2 s audio codec + voice pcm interface 21 track id: jatr-1076-21 rev. 1.0 7.9. avc control the automatic volume control (avc) function dynami cally adjusts the input signal quantized by the adc to an expected sound level by setting thmax and thmin. when the average level of input signal is higher th an thmax, the avc will decrease the selected analog gain to attenuate the quantized pulse code modula tion (pcm) signal to a lower amplitude than thmax. when the average level of input signal is lower th an thmin, the avc will incr ease the selected analog gain to amplify the input signal. the quantized pulse code modulation (pcm) signal is then set higher than thmin. the quantized pcm has an average level between thmin and thmax. the avc reference source channel and target ch annel can be individually set by index20[0] and reg5e[13:12]. the avc architecture is shown in figure 12 below: figure 12. auto volume control block diagram www.datasheet.co.kr datasheet pdf - http://www..net/
ALC5620 datasheet i 2 c + i 2 s audio codec + voice pcm interface 22 track id: jatr-1076-21 rev. 1.0 7.10. hardware sound effects the sound effect block is composed of pseudo ster eo, spatial 3d, and equalizer blocks. the pseudo stereo block is used to convert a mono source into virtualized stereo output. the spatial 3d block is a surround sound generator with adjustab le amplitude (gain) and surroun d depth (ratio). the equalizer block can be used to compensate fo r speaker response, or to make e nvironment sound effects, e.g., ?pub?, ?live? , ?rock?,? etc.. 7.10.1. equalizer block the equalizer block cascades 5 bands of equalizer to compensate for speaker response and to emulate environment sound. one high-pass filter cascaded in the front end is used to drop low frequency tone, which has a larger amplitude and may damage a mini speaker. the high-pass filter can also be used to adjust treble strength with ga in control. a low-pass filter with gain control can adjust the bass strength. three bands of bi-quad ban dpass filters are used to emulate environment sounds. to avoid pcm sample saturation, the digital volume control has up to 18db of attenuation before the equalizer. a 0~+18db digital gain after the equalizer is used to correct pcm output to a suitable level. 7.10.2. pseudo stereo and spatial 3d sound there are two spatial effects in post-processing; the ps eudo-stereo effect + spatial effect, and the stereo expansion effect. the pseudo-stereo effect + spatial effect convert s a mono signal to a stereo signal by changing the phase and amplitude of the original signal followed by enhancing the spatial effect. the stereo expansion effect enhances the spatial effect when the input signal is stereo. www.datasheet.co.kr datasheet pdf - http://www..net/
