External Audio ADC/DAC, SPDIF input interface
Audio ADC/DAC interface provides a high quality multi resolution(16/18/20/24-bit) digital audio connection to external audio
devices. ADI interface supports I2S audio format as well as optional left-justified or right-justified audio format. ADI interface
produces one 64-bit frame at the audio sample frequency using a bit clock and frame sync signal in master mode. In slave mode,
ADI accepts one 64-bit frame in audio DAC or one 64/48-bit frame at the audio sample frequency using external generated
control signal. ADI interface supports several audio sampling frequency up to 96-kHz such as 32, 44.1, 48, 64, 88.2, or 96-kHz,
of which 256 or 384 times main clock can be generated from on-chip audio PLL or external clock signal by interface mode
programming. ADI interface contains dual on-chip FIFO which size contains maximally 2048 samples with 16-bit or 1024
samples with above 16-bit stereo audio data through YMEM2 shared with RISC/DSP processor.
