Datasheet

7.5. Audio Data Path

7.5.1. Stereo ADC

The stereo ADC is a high performance ADC. The full scale input of ADC is 1Vrms at AVDD is 3.3V. In

order to save power, the left and right ADC can be powered down separately by setting the related

register. The volume control of the stereo ADC is also can set by registers.

7.5.2. Stereo DAC

The stereo DAC is a high performance DAC. The sampling rate can be configured by setting the stereo

I2S clock divider. The volume control of the stereo DAC is set by registers.

7.5.3. Mixers

There are seven analog mixers in ALC5633Q.

• Headphone mixer - HPMIXL/R

The stereo headphone mixer can do mixing for DAC outputs and analog inputs. The mixer output is

mainly for headphone output. Each input path has mute function to the mixer block.

At headphone output has another mixer for headphone volume output and direct DAC output. From

headphone volume output has it’s volume control and from DAC is also has it’s volume control –

digital volume. For different source and independent volume control, can use this mixer to implement.

• Speaker mixer – SPKMIX

The speaker mixer can do mixing for DAC outputs and analog inputs. The mixer output is for speaker

output. Each input path has it’s mute function to the mixer block.

• Aux Output mixer – AUXMIXL/R

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 path has individual mute function to the mixer

block.

• Record mixer – RECMIXL/R

The stereo analog mixer can do mixing for analog input and output mixer. The mixer output is for

ADC input. Each input path has it’s mute function to the mixer block.

# Each mixer has it’s power down control by register. And can power down single channel of stereo

mixer independent. It can easy to control the power management to achieve enhance power saving.
