Description
The AC107 is a highly integrated 2-channel ADC with I2S/TDM output transition. It&＃39;s designed for multi-microphone array in high definition voice capture and recognition application platforms.
The integrated digital PLL supports a large range of input/output frequencies, and it can generate required system clocks from common reference clock such as 6-/12-MHz, 6.144-/12.288-MHz, 5.6448-/11.2896-MHz,
13MHz, 19.2MHz, 24.576MHz and other non standard audio system clocks. The audio sample 8kHz, 11.025kHz, 12kHz, 16kHz, 22.05kHz, 24kHz, 32kHz, 44.1kHz, 48kHz, 96kHz is supported.
The AC107 integrates stereo synchronized ADCs with independent programmable mic bias voltage and mic boost amplifier to deliver valid channel data that channel crosstalk can be eliminated. The analog input port MIC1P/N ~MIC2P/N is designed as two differential microphone pin or single-ended line-in pin. Independent digital volume controllers are provided in each channel.
The AC107 can transit its 2 channels output data over the I2S port by standard I2S or PCM format. Also, one to eight device can be combined to transit up to 16 channels output data by a single TDM line. Furthermore, A new format called encoding mode can be used to transit 16 channels data when the I2S format of AP is normal protocol types.
The AC107 is controlled through TWI (2-wire serial interface, I2C compatible). The clock supports up to 400 KHz rate. It works only in the slave mode.
