GENERAL DESCRIPTION
First I2S interface can support dual mode: normal I2S and I2S with TDM (Time Division Multiplexing) interface. Also the received data can to headphone output, line output or PDM output. Asynchronous Sample Rate Converter (ASRC) provides independent and asynchronous connections to different processors, such as an application processor, baseband processor or wireless transceiver(BT). The Pulse Density Modulation (PDM) output interface can drive external PDM Class-D amplifier. The PDM interface is also build in 8-bits pattern control function for control external PDM amplifier. The ALC5651 features an ultra low power cap-free headphone amplifier. It consumes only less than 5.5mW power during playback, providing mobile system longer battery life under headphone listening mode. The integrated DRC(Dynamic Range Controller) and 7-band parametric Equalizer provide further digital sound processing capability of audio playback paths. The DRC in ALC5651 continuously monitors the DAC output level.
