7.7. AVC Control

The Automatic Volume Control (AVC) function dynamically 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 than THmax, the AVC will decrease the selected analog

gain to attenuate the quantized Pulse Code Modulation (PCM) signal to a lower amplitude than THmax.

When the average level of input signal is lower than THmin, the AVC will increase 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 channel can be individually set by Index20[0] and

Reg5E[13:12].

The AVC architecture is shown in Figure 8 below:
