GENERAL DESCRIPTION
Three I2S interface can connect to different devices and let the ALC5670 to be an Audio Hub. Asynchronous Sample Rate Converter (ASRC) provides independent and asynchronous connections to different processors, such as an application processor, baseband processor or wireless transceiver(BT). It consumes only less than 5mW power during playback, providing mobile system longer battery life under headphone listening mode. The integrated multi-section DRC(Dynamic Range Controller) and 14-band parametric Equalizer provide further digital sound processing capability of audio playback paths. The multi-section DRC in ALC5670 continuously monitors the DAC output level. When the power level is low, it increases the input signal gain to make it sound louder. At the same time, if a peaking signal is detected, it autonomously reduces the applied gain to avoid hard clipping. It ensures the maximum/consistent signal amplitude without producing audio clipping and speaker damage. The...
