ALC5651-CGT Product Details
The ALC5651 is a high performance, low power, dual I²S interface audio CODEC. First I²S interface can support dual mode: normal I²S and I2S with TDM (Time Division Multiplexing) interface. The TDM interface can transmit/receive up to 8 channels data. The transmitted data can from analog input or digital microphone input. 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. 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 7-band parametric Equalizer contains 7 independent filters with programmable gain, center frequency and bandwidth to tailor the frequency characteristics of embedded speaker system according to user preferences.
For microphone recording, the DRC in ALC5651 can be used as AGC(Auto Gain Controller) to maintain a constant recording volume. Besides, a dynamic wind reduction filter is built in on recording path. The filter can detect the level of wind noise and on/off dynamically to keep the recording quality.
SounzRealTM digital sound effect technology is configurable to provide better listening experience. OminiSound EXPTM expands the sound field of embedded stereo speaker. BassBack EXPTM (low frequency effect) to listeners without subwoofer needed. TruTreble EXPTM adds processed harmonic tones at high frequency, bringing more melody and details for music listening.
ALC5651 only requires two voltage supplies and consume ultra low power, making it ideal for mobile devices.
