Datasheet

7.7. Analog Audio Input Path

The ALC5624 supports four Analog Audio Input paths:

• Line_IN_L/R

• PHONEP/N

• MIC1

• MIC2

7.7.1. Line Input

Line_In_L and Line_In_R provide 2-channel stereo single-ended input that can be mixed into the MONO

mixer, Headphone mixer, Speaker mixer, or the ADC record mixer.

The Line_In_L/R volume and mute are controlled by Reg0A. Reg3E[7:6] can be used to power down the

Line_In volume control.

7.7.2. Phone Input

PHONEP/N provides one-channel MONO differential or single-ended input configured by Reg08[13]

that can be mixed into the ADC record mixer, or any analog output mixer except for the MONO mixer.

PHONEP is main input when differential mode is disabled.

The PHONEP/N volume and mute are controlled by Reg08.

Reg3E[5:4] can be used to power down PHONEP/N volume control and mixer.

7.7.3. Microphone Input

MIC1P/N and MIC2P/N provide two-channel stereo differential or single-ended input via Reg10[12], [4],

that can be mixed into the ADC record mixer, or any analog output mixer. MIC1P and MIC2P are main

inputs when differential mode is disabled.

The ALC5624 Microphone input boost provides 20/30/40dB boost, set by Reg22[11:10] (for MIC1), and

by Reg22[9:8] (for MIC2). The MIC1/2 volume and mute are controlled by Reg0E.

For detailed power management of MIC1/2, Reg3E[3][2] can be used to power down the MIC1/2 volume

control. Reg3E[1][0] can be used to power down MIC1/2 boost.
